GENERAL INFORMATION

021517>01

Notes The LIEBHERR overload safety device LICCON is a safety device for cranes which assists the driver to operate the crane safely by displaying important data for lifting loads in the driver's cabin, announces any approaching overload conditions and shuts down all crane movements which may increase the load torque if overloading occurs. DANGER The existence of the overload safety device does not free the crane driver of his duties as far as safety is concerned because the device is not able to register all influences that can have an effect on the crane. For that reason it is possible that a crane, in spite of a functioning and correctly adjusted overload safety devi> ce, can topple or be destructed if, for example, 1. the ground under the supports gives way, 2. the crane is not set up horizontally and the load is slewed towards the gradient, 3. when carrying out disassembly work a heavy load is slung on to which, after unscrewing or cutting free, is hanging free in the crane, 4. a fixed load is drawn which suddenly becomes free, 5. excessive forces occur by moving the load too quickly or suddenly, 6. high winds occur, 7. pulling at an angle is carried out, etc. The crane driver must be acquainted with such situations and take them into account when setting up and operating the crane. Only in this manner can the overload safety device fulfill its purpose and help to make operation of the crane safer.

1.2

Instructions In the Federal Republic of Germany the directives of the VDI (Verein Deutscher Ingenieure = Associa> tion of German Engineers) 3570 are valid for working with overload safety devices for cranes. These con> tain reference to the meaning and limits of the overload safety device: ∫Overload safety devices are constructed, where possible, to prevent accidents and danger to persons, things, the load and the crane as a result of overloading during the operation of cranes. Operators and crane drivers must take into consideration that an overload safety device cannot register all dangers at the right time and that a disturbance can be caused by influences not readily recognisable. For this reason circumspection and responsibility for the observance of the operating regulations and loa> ding of the crane still lie in their jurisdiction. Overload safety devices may not be used for directing general operation. They exist for emer> gencies. The load carrying capacity of the lifting apparatus should not be decreased by an over> load safety device∫.

GENERAL INFORMATION

1.3

Information for overload safety devices of boom cranes Publisher: VDMA > January 1970

021517>01

The boom crane which has been delivered to you is equipped with an overload safety device (overload shutdown device) according to ß24 of UVV 'Boom cranes' by which the hoisting gear and the boom luffing gear of the crane is switched off if the allowable load torque is exceeded. To relieve the overload after a signal from the overload safety device the contra>rotating motion must be able to be carried out. That means, for example, that the load must be able to be released after shutting down the hoisting gear. Installing the overload safety device (overload shutdown device) should prevent the crane taking loads which endanger its stability. The overload safety device (overload shutdown device) is an emergency shutdown which shut downs all motion which increases the load torque in case of overloading and thus prevents possible damage or an accident. The following must be observed so that the overload safety device can fulfill its function: 1.

The overload safety device (overload shutdown device) may not be used in course of operation for shutting down the hoisting device or boom luffing gear. The crane driver must always be convinced of the fact that the load to be lifted does not exceed the load carrying capacity of the crane. Loads which are too heavy, which exceed the load carrying capacity of the crane may not be lifted even if the overload safety device is installed. It may on no account be used as scales or the crane be loaded over its allowable load.

2.

Tearing loose of fixed loads may only be done with the agreement of the manufacturer of the crane and only with such cranes which are constructed for this purpose. In such cases the overload safety device (load torque limiter) may not be used as operational device for measuring power.

3.

The built>in overload safety device must be serviced regularly and checked before starting use so that the safety of function is ensured. According to ß 35 of UUV 'Boom cranes' regular checking of the overload safety device is included in servicing the crane.

4.

In general the overload safety device does not change>over automatically to the different operational conditions of the crane. For this reason the crane driver has the responsibility, if the operational condition of the crane is changed, to change>over the overload safety device to the changed carrying power or load torque range. The manufacturer's operating instructions for the built>in overload safety device must be observed. Safe functioning of the device and unendangered working of the crane is largely dependent on this regulation being observed carefully. An overload safety device which is not correctly adjusted, e.g to large load torque with retracted supports, is much more dangerous than a crane without overload safety device for the reason that the crane driver has a false feeling of security which can lead to serious accidents.

5.

The built>in overload safety device (overload shutdowndevice) must be changed>over by the crane driver, if the operational condition of the crane is changed, to the changed carrying power or load torque range, e.g. a) when the supports are extended or retracted (change>over to large or small load torque) b) if the boom length is changed by > extension or retraction (telescoping) manually, > assembly and disassembly of intermediary pieces, c) when rotating or slewing the crane into the range of larger or smaller datum torque (change>over to large or small load torque) d) when transferring to a different load carryingcapacity range by multiple reeving in of the cable lines of the hoisting device or boom luffing gear.

6.

It is most important to note that incorrect operating ofthe crane means that the overload safety device is not effective or that the driving unit is not shut down quickly enough. In this case accidents can occur in spite of an overload safety device. This is particularly true, for example, for > latching down of the load or lifting tackle, > excessive decelerating power, > load falling into cable > pulling at an angle > moving crane into an area of large gradient, > earth giving way, > high wind.

7.

If a device for shutting down or bypassing theoverload safety device (load torque limiter) is existent, this may only be used taking special precautions in the presence of the crane supervisor, e.g. when carrying out the crane check and in times of use stated by the crane manufacturer.

At no time may the overload safety device be switched off or bypassed during operation for taking up loads any of which exceed the allowable load carrying capacity of the crane. Careful observance of these instructions and those contained in the manufacturer's operating instructions is a precondition for the safe functioning of the overload safety device (overload shutdown device). In any case of doubt the manufacturer's operating instructions should be consulted. If this is not sufficient the company concerned should be consulted. Any measures undertaken by the operator as far as the mechanical system of the overload safety device result in the loss of guarantee.

SYSTEM DESCRIPTION

3.1

General

024110>00

The LICCON overload safety device functions according the principle of rated and actual value comparison . Rated (preset) values The crane data, such as load capacity charts, boom weights and geometrical parameters are stored in the central data memory of the LICCON safe load indicator (overload safety device). This data forms the reference information used to calculate the overload conditions, the rated values, which must be compared with the constantly determined actual values. Actual values: The actual crane load is determined through the registration of changing values, such as: 1. The load of the crane, which is a combination of load momentum and boom momentum, creates a certain hydraulic pressure in the boom luffing cylinder ( or in the luffing cylinders), and this pressure is measured by a pressure sensor. 2. The boom radius (reach) is determined by measuring the boom length and the boom angle in relation to the horizontal line. The flexure of the boom , which is caused by its own weight and the weight of the load, is also taken into consideration. In a microprocessor > electronic systemπs central processing unit , part of the electronic component group (4), the rated and the actual values are being compared. As soon as the rated and preset limits are approached, an initial warning is given; when the limit values are reached or exceeded, the overload safety device is triggered and any crane movements, which would increase the load momentum, are shut down.

THE ∫SET UP∫ PROGRAM > THE EQUIPMENT SET UP VIEW

024112>00

The ∫SET UP∫ program offers the crane operator the possibility, to adjust the LICCON on the screen via the equipment set up view and control elements to the actual current operating mode, the actual current equipment configuration and the reeving number of the hoisting cable on the screen the control elements. The operator presses the appropriate function key or enters a short code, which allows him to view the data on the load capa> city chart and, if necessary, passed on to other programs, such as the ∫OPERATION∫ program. After the system is turned on it runs through a self test, and then starts the ∫SET UP∫ program automatically. The screen shows the view of the last equipment set up configuration and the last hoisting cable reeving confi> guration. When the unit is turned on for the first time, or after a data memory loss (COLD START), the first valid equip> ment configuration and the first valid operating mode is automatically set and displayed. CAUTION:

The hoisting cable reeving number is set to ∫0∫ in this case !

In the ∫SET UP∫ program > equipment set up view, the screen is divided into three sections: 1. General information line 2. Display area for the values of the load capacity chart 3. Function keyboard

Note:

The views shown in this chapter are only examples. The displayed values in the different symbols and charts might not necessarily correspond to your crane model .

4.1.1

General information line

024112>00

The following symbols and information are found in this line, from left to right: 1)

∫Telescoping boom length ∫ symbol (has the same appearance for all operating modes)

2)

Abbreviations for the programmed units of length (LE) and units of weight (GE). LE units are either gi> ven in meters [m] or in foot [ft]. GE units are either given in tons [t] or [lbs].

3)

Next to the word ∫CODE∫ is the 3 digit short code. Every short code describes the set up condition of the crane. The valid set up conditions for the crane and the corresponding short code numbers are found in the load capacity chart.

4)

An 8 digit organizational number (Taxx yyyy) depends on the operating mode of the adjusted load capa> city chart. This organizational number begins with the letter T (=Tabelle ( =chart). The letter in the 2nd place shows the calculation basis of the load capacity chart according to the country (for example: ∫B∫ = DIN, BS 75%), the following number combination (xx) describes the crane type (for example ∫80∫ = LTM 1300) . The 4digit character block (yyyy) defines the operating mode.

5)

The page number of the currently displayed part of the load capacity chart is shown separated from the organization number by a period ( ∫.∫ ) , behind it in parenthesis ( ) is the total number of pages of this load capacity chart (see also description of the F1 function key in chapter 4.1.3).

4.1.2

Display area for the values in the load capacity chart

024112>00

This area is divided in the following sections: 1)

Telescopic boom lengths in length units (LE), either in meters ([m] or in feet [ft]) in max. 7 columns per page. They form the horizontal axis of the fields of the load capacity chart.

2)

The ∫Working radius / reach ∫ symbols,which depends on the operating mode, in units of length (LE), either meters ([m] or feet [ft]) , below it, a maximum of 10 lines of working radius values. The form the vertical axis of the fields of the load capacity chart .

3)

Load capacity value field In the columns below the telescopic boom lengths and the lines to the right of the working radius values are the load capacity values dependent on the boom length and the working radius.

4)

Line ∫n∫ = Hoisting cable reeving The numbers in this line show how often the hoisting cable must be reeved between the boom head and the hook block in order to lift the maximum load of the corresponding load capacity chart column. If a lo> ad capacity value in the column exceeds the load which can be lifted with the max. possible cable ree> ving, then an exclamation mark (!) next to the reeving number shows that a special attachment is requi> red to lift this load.

5)

Line for special displays If a load capacity chart consists of more than 7 columns, then it cannot shown completely on the screen, due to its size. In this case, arrows in the 1st field () of this line show that to the left or right of this chart are additional columns, which can be viewed by pressing the keys ∫∫ (see section E in chapter 3.2). In addition, column numbers can appear in this line, which can give indications later in the crane operating view to the interpolation of the maximum load calculation.

6)

∫Extension condition of telescopic section in percentages [%]∫ In the first column is the ∫boom length ∫ symbol [%]. Next to it are 4 lines for the extension condition of the telescopic section. They are filled with values depending on the number of telescopic sections (de> pending on the type of crane) and possibly with a status indicator (such as . ∫+∫ = pinned) . The num> ber in the symbol column describes the corresponding telescopic section (the higher number is for the outermost telescopic section) and the value in the ∫Boom length∫ column shows the extension condition in percentages, which must be retained for the corresponding boom length. The status indicator, if shown, is directly next to the percentage value.

4.1.3 The function keyboard The function keyboard contains 8 FK symbols, which correspond to the function keys below them, which means they either mark a function, which can be selected with the function key (F1 and F8) , or they change their ap> pearance or their content and indicate a change in operating mode or equipment configuration . F1 Vertical paging Due to the size of the monitor screen, no more than 10 load capacity chart lines can be shown at the sa> me time. If the chart consists of more than 10 lines, then the view is divided into several pages (see also point 4.1.1 , paragraph 5). By pressing the key, the next page of the load capacity chart appears and the number of the current page shown in the ∫General information lines∫ increases by 1. When the last page has been reached, and the F1 key is pressed, page 1 reappears. F2 Setting the operating mode (main boom) The different main boom operating modes of the crane, if installed, can be set here. The different modes are abbreviated, with length data, support base or tires dimension in the symbol .

Hoisting cable reeving The number of hoisting cable lines (reeving) shown in the symbol can be increased by one by pressing the key until a predetermined maximum value has been reached, which depends on the operating mo> de; then the counter starts over again at the minimum value. If the adjusted value is within this range when changing the operating mode (minimum value e actual value e maximum value), then is re> mains valid. Otherwise it will be set tot he maximum value for the new operating mode.

024112>00

Note: After a ∫cold start∫ , for example after a data memory loss ) the display for the hoisting cable ree> ving is on ∫0∫. F8

O.K. > Confirmation of adjusted equipment configuration The crane operator pressed the ∫O.K.∫ key to confirm the correct equipment configuration (corresponds to the actual crane equipment configuration or set up mode) and transfers the parameter to the ∫OPE> RATION∫ program. Note the following: a) The adjustment of the equipment configuration must be completed, that means a valid short code is displayed and there are load capacity values in the table field (OERROR 50). b) The external conditions for this configuration, if necessary, must be set (for example: superstructu> re locked ) (OERROR 51) c) In its previous equipment configuration, the crane may not have been loaded in excess of 20% and the load suspended from the hook may not be heavier than 0.5 t. (OERROR 52). In this case a changeover to the ∫OPERATION∫ program can only be made via the P1 program key. The adjusted equipment setup will not been taken over in this case. d) The required number of central processing units must be inserted and operative (OERROR 499). Note:

After changing over to the ∫OPERATING VIEW∫ the crane operator must ensure in every case that the equipment setup (short CODE) and the hoisting rope reeving value are taken over. (see 4.1.2).

4.1.4 Other operating elements The remaining operating elements for the display and control unit for the LICCON system in the ∫SET UP∫ program have the following functions: 1

Alpha numerical keyboard By pressing the alpha numerical keys 1..9, it is possible to write directly into the short code field of the general information line. All operating and set up dependent data disappears from the screen. The keys ∫p∫ and ∫.∫ doe not have any function in the ∫SET UP∫ program.

2

Program keys With the program keys you can choose from the individual programs. However, you still must observe the program specific peculiarities (for example, from ∫SET UP∫ you must always press 1¥ the O.K. key to switch to ∫OPERATION∫). The presently running program cannot be recalled via its program key.

3

∫ENTER∫ key Press the ∫ENTER∫ key to confirm an entry of a short code or a change of the equipment configuration via the function keys. When pressing ∫ENTER∫ after the short code entry, it searches for the short code in all stored load capa> city charts.

THE ∫OPERATION∫ PROGRAM > THE CRANE OPERATING VIEW

024113>00

The LICCON ∫OPERATION∫ program supports the crane operator by constantly displaying the relevant data for the crane operation on the screen (crane operating view). In addition, the crane operator is made aware of approaching overload conditions. In overload or error situations, which could lead to dangerous movements, any movements which would increase the load momentum are shut off. For the crane operating view, the screen is divided into six sections: 1. Information about crane geometry and load 2. Alarm functions 3. Special functions 4. Additional monitoring functions, divided on 2 pages 5. Cable winches 6. Function keyboard

Note: The pictures in this chapter are used only as examples. The values shown in the different symbols might not necessarily fit to your crane model. In addition, the sample pictures show the maximum pos> sible number of symbols on the LICCON screen. For normal crane operation, an identical view such as this sample would not appear on your LICCON screen.

Information regarding crane geometry and load

024113>00

1) Maximum load capacity This symbol shows how much load in GE ([t] or [lbs]) can be lifted in the current crane operating condition. In the same symbol, the reeving number of the hoisting cable is noted as ∫n = ∫ (it was entered previously in the equipment set up program). The maximum permissible load capacity depends on the cho> sen equipment configuration (load capacity chart), on the telescoping condition of the boom, on the working radius and the reeving of the hoisting cable.

2) Current load capacity (actual load display) This symbol shows how much load in GE ([t] or [lbs]) is currently suspended from the crane. The total load is displayed, including the weights of the carrying, lifting and / or tackle. By using the ∫NET LOAD CAL> CULATION∫ function (refer to description F7 in chapter 4.2.6), the display can be changed over to display the net load. The symbol then displays the word ∫net∫, the character for the weight unit (for example ∫t∫ for ton) is shown next to the load symbol.

3) Boom radius (reach) and main boom angle This symbol shows the working radius or reach in units of length, such as meters [m] or feet [ft]. The boom radius (reach) is determined by measuring the horizontal center of gravity of the load from the axis of rota> tion of the crane superstructure, measured at the ground. The flexure of the boom due to its own weight and the weight of the load is also taken into consideration. In addition, the momentary angle position of the main boom to the horizontal line is displayed in degrees ( ∞ ).

4) Length of the main boom This symbol shows the total length of the main boom in units of lengths, as meters ([m] or feet [ft]) in large letters. The extension condition of the individual telescopic sections is shown in percentage [%] in normal sized letters. The number of percentage values, separated by diagonal lines ( / ) depends on the number of telescopic sections installed in the crane model.

5) Height of the pulley head This symbols shows the vertical distance of the boom pulley head from the base of the crane in units of length, in meters ([m] or feet [ft]).

6) Crane capacity and operating mode This symbol shows at what percentage of its capacity the crane is being used, this percentage is shown in the form of a bar, which changes in length. This bar indicator moves along a scale, the most important points are marked by percentage values. The 8>digit organization number and the short code (CODE >number THE CRANE OPERATING VIEW

4.2.2 Alarm functions The crane movements are monitored in their limit ranges and as soon as the limits are reached, the crane operator is alerted to that fact by symbols, which appear on the monitor.

1) Boom limit The luffing range of the telescopic boom is limited upward as well as downward. As soon as the limit posi> tion during luffing of the telescopic boom has been reached, this symbol appears. One or two arrows poin> ting to the top or to the bottom show which limit position has been reached. This means: one arrow shows that the limit is being determined by the selected load capacity chart, two arrows show that the mechanical stop of the boom has been reached.

2) Upper limit of hoisting movement on main boom The upward movement of the hook block (of the load hook) is monitored by the upper hoist limit switch . If this limit switch actuates, the crane movements ∫ spool up winch ∫, ∫ luffing the boom∫ and ∫ extending the boom∫ are shut down and this symbol appears on the screen (for bypass possibility, refer to description ∫key operated switch, chapter 4.2.7, section 6. )

3) Upper limit of hoisting movement on auxiliary boom The same as noted in section 3) is valid for the auxiliary boom.

4) Pre>warning A preliminary warning stage is programmed into the crane capacity monitoring system, which actuates be> fore the load limit is reached. If this limit is exceeded, this symbol appears on the screen.

5) STOP If the crane capacity is being exceeded, the STOP symbol appears and the horn sounds an audible alarm. All crane movements which would increase the load momentum are shut off. (For bypass possibility, refer to description ∫keyed switch, chapter 4.2.7, section 6.)

4.2.4.1 Additional function (Crane inclination∫ This symbol shows the incline of the crane to the horizontal line in longitudinal and transverse direction. The indication is shown graphically as well as numerically. The graphic view has the shape of a bubble gauge with a moving point (small square(, which represents the air bubble. The center of the point shows the exact value. In the numerical part of the symbol, three numerical values appear with the following meaning (from top to bot> tom): 1st value

This value shows the code for the graphical view, the distance of 2!lines (longitudinal and transver> se) of the gauge. it is shown in units (degrees) and can only take on the two values ∫0.2∫ or ∫1∫. The range change over occurs automatically. If the crane inclination is in transverse direction rection of inclination: Arrow to the top > the crane leans to the rear .

Note:

All indicators in the crane inclination symbol refer to the position of the crane chassis accor> ding to the below listed ∫supporting force monitor∫, which means the crane operator always views the instruments against the direction of travel (in main working direction ∫to the re> ar∫.

4.2.4.2 Additional function (Wind speed (velocity)∫ The wind speed is shown either in meters [m/s] or in foot [ft/s] , depending on the measuring units used in the load capacity chart. The below listed maximum permissible wind speed (same measuring unit) is dependent of the operating mode, the equipment configuration and the boom length. If the actual value of the wind speed ex> ceeds t the maximum shown value, then the symbols will start to blink and the acoustical alarm ∫SHORT BEEP∫ will sound. However, the crane movements are not shut off. 4.2.4.3 Additional function (Supporting force monitor∫ During crane operation, the LICCON supporting force monitor constantly monitors the actual hydraulic pres> sure in all 4 support cylinders with a pressure sensor and calculates the supporting force in tons (t) for each out> rigger. These supporting fores can be checked by the operator as needed, in the ∫crane supported™ mode, or they are displayed automatically, in case a critical situation arises. a) Display of actual supporting force Press the F3 function key to show the (Supporting force monitor∫ symbol , next to the crane symbol, the supporting force for every outrigger is shown. The symbol appears automatically with the alarm signal (short beep∫, if one of the supports either reaches or exceeds the maximum force, or if it reaches the minimum force or falls below it. The value or values which triggered the warning are blinking . The crane movements are not shut off. CAUTION:

Blinking question marks (???∫ instead of a value figure,along with an error number 62 / 63 in the FK6 ERROR symbol point to an error in the corresponding pressure sensor or in the connecting line to that sensor .

b) To program the maximum and minimum supporting force values Depending on the crane model, the same maximum and a combined minimum supporting force value has been preprogrammed at the factory. However, with the (SUPPORTING FORCE LIMIT VALUE MODIFI> CATION ∫ program, the crane operator can change these 5 values if needed (refer to chapter 4.4).

4.2.5 Cable winches The function of a maximum of 2 cable winches is monitored for hook path and direction of rotation. Depending on the operating mode, different cable winches can be switched to these two indicators. The cable winches are marked in the symbol by a number. The 4 or (5) digit number on top of the symbol shows the completed hook path, as calculated from a preset zero point in units of length units, meters ([m] or feet [ft]) . (Refer also to chap> ter 4.2.6 for the description of the F1 and F2 function keys). The arrow in the symbols shows the direction of the hook movements in relation to the zero point (if arrow points to the top = hook has moved upward from the zero point). the two blinking arrows in the winch cable sketch (hoisting cable) show the direction of movement of the cable during the winding process. For the calculation of the completed path, the hoist cable reeving is taken into consideration (a prerequisite for the correct calculation is of course that the entered value matches the actual number of cable sheaves between book head and hook block). The following factors are not taken into consideration: > Flexure > Cable expansion > Position jump if the zero point of the cam limit switch of the corresponding cable winch has not been correct> ly adjusted. The hook path calculation only works accurately if the load hangs freely, and no luffing or telescoping move> ment takes place if during the hoisting procedure. An adjustment of the hook path display can be made by spoo> ling the cable out until the cam limit switch actuates ( lower limit of the boom). Note:

In multiple winch operation, an exact hoop path calculation can only be made for that hoi> sting winch, whose hook block was reeved to match that the hook block configuration of the equipment mode. If the reeving of the winch does not match this pre>entered value, then the correct hook path can be calculated according to the following formula:

displayed hook path ¥ preadjusted reeving correct hook path= actual reeving

4.2.6 Function keyboard (FK) The function keyboard contains up to 8 FK symbols, which correspond to the F1 ... F8 function key below it, which means they characterize either a function, which can be triggered with the corresponding key and / or they can change their appearance and meaning by pressing the key . F1 Zero point for hook path indication > winch (L = left) If monitoring is intended in the left winch field, then the symbol (Set winch zero∫ appears above this key and the function is active, which means that if the key is pressed, the hook path indication in the winch symbol above it is set to ∫00000∫ and the hook path is measured from this point. F2 Zero point for hook path indication > winch (R = right) As for F1 for the right winch field. F3 Monitor ON / OFF With the F3 function key (∫Caution∫ symbol in the FK frame), the crane operator is able to turn all additio> nal monitoring symbols, which are available for his crane, on or off. The appearance of the FK symbol changes accordingly: (Thick frame∫ = Monitoring function is OFF (Thin frame™ = Monitoring function is ON F4 Change monitoring side This function key only becomes active and the FK symbol (arrow in FK frame) only appears, if the triggered function makes sense (refer to paragraph 4.2.4 (Monitoring additional functions∫). The following criteria applies: a) Symbol not displayed > No additional function to be monitored is defined on page 2 , > Monitoring function is turned off via F3 and there are no errors in additional functions, or there is an error in not more than one monitoring side. b) Symbol displayed > Monitoring function is turned on via F3 and there are no errors in additional functions of the currently not displayed monitoring side. c) Symbol blinks > Monitoring function is turned off via F3 and there is an error in the additional function of both monitoring sides. > Monitoring function is turned on via F3 and there is an error in the additional function of the currently not displayed monitoring side.

F5 Bypass selection With this key operated switch (refer to description in chapter 4.2.7 , section 4) any LICCON shut off mecha> nisms, which would restrict crane movement, can be bypassed. The cause of the shut off, which is to be bypas> sed, is selected with the F5 key > by pressing the key, the next FK symbols appears via F5 > and is triggered by holding the keyed switch (4) in ∫right positionπ. The FK symbol begins to blink. Two shut off mechanisms can be bypassed by preselection: 1. Overload shut off (Crane at 100% capacity) In the FK symbol appears the text ∫100%∫, which is crossed out diagonally. This is also be basic adjustment. 2. Upper hoist limit shut off In the FK symbol appears a load hook with arrow on ∫top∫ stop, crossed out diagonally.

F6 ERROR In case of an operational problem occurs ( = a problem which does not immediately shut down the system) , the FK symbol frame with the word ∫ERROR∫ appears in the F6 key, along with a 3 digit error code number . As soon as the problem has been remedied, the symbol disappears from the screen. The F6 key only triggers reac> tivation of the acoustical warning signal, which may have been turned off.

F7 Net load calculation The load hook symbol and the number ∫0∫ in the FK symbol frame describes the function. When the F7 key is pressed, the actual load indicator (refer to paragraph 4.2.1, section 2) is set to ∫zero∫ . At the same time, the word ∫net∫ appears in the symbol of the actual load value (paragraph 4.2.1, section 2) . Due to this function, it is possible to eliminate the weights of the hoisting cable, tackle, lifting and slinging devices and to indicate only the weight of the load to be lifted (net load). This calculation can be canceled by three ac> tions: 1. Pressing the F7 again, 2. Telescoping the boom by more than 3 units of length ( dm or 1/10 ft ), 3. Luffing by more than 4 ∞ (degrees). The word ∫net∫ disappears from the actual load indicator symbol (4.2.1, section 2) and the gross load value is indicated again.

F8 Horn OFF The diagonally crossed out horn symbol in the FK frame above the F8 key describes the function. The acoustical HORN and SHORT BEEP warning signals can be turned off by pressing the key. A new error will turn the acoustical warning on again. Special function of the F8 FK symbol When the crane is put in service, the user has a special program available on the LICCON system. In order to prevent any erroneous functions, only especially trained LIEBHERR personnel may access the system. The user must lock the program after completion of work. The condition of the program, when it is taken over, is marked in the FK symbol ∫HORN OFF∫ . An additional mark (claw) in the symbol indicates that the original program, as it was taken over when the machine was put in service, has not yet been blocked.

Key operated switch The key operated switch (4) has 2 shift position. The position ∫Center notch∫ is active during crane opera> tion. In this ∫right notch∫ position, the shut off mechanismsfor restricting crane movementcan be bypassed. After preselection via the F5 key (refer to description in chapter 4.2.6), the overload shut off or the upper hoist limit shut off limit can be bypassed. a) To bypass the overload shut off As soon as the maximum permissible load momentum is being exceeded, the LICCON safe load indica> tor shuts off all crane movements which would increase the load momentum. This shut off function can be bypassed by moving the keyed switch (4) to ∫ ∫right notch ∫ position. However , this function may on> ly be bypassed in presence of the crane supervisor and then only with utmost care and caution. All LIC> CON safe load indictors remain functioning. However, now no other additional protection against over> loading the crane is available. An external red flashing light on the crane operatorπs cab signals that the crane operator has bypassed a shut off function.

DANGER:

If the overload shut off is bypassed, there is an INCREASED RISK OF ACCI> DENTS !! UTMOST CAUTION is necessary!!

b) To bypass the upper hoist limit shot off If, during the upward movement, the hook block touches the weight of the hoist limit switch, the hoist limit switch actuates. The crane movements ∫winch in∫ , ∫extend telescopic boom™ and ™lowering teles> copic boom are turned off. These shut off function can be bypassed by turning the keyed switch (4) to ∫right notch ∫ position (preselection via F5) . However , this function may only be bypassed in presence of the crane supervisor and then only if the crane operator is in direct contact with another person who constantly monitors the distance of the hook block and the boom head. The crane should only be moved with utmost caution and at the slowest possible speed. An external red flashing light on the crane ope> ratorπs cab signals that the crane operator has bypassed a shut off function. DANGER:

If the upper hoist limit shut off is bypassed, there is an INCREASED RISK OF AC> CIDENTS !! UTMOST CAUTION is necessary!!

The ∫HORN∫ is a half a second beeping sound, which is re> peated in one second intervals. Monitored sensors are: > Hoist limit switch > Pressure sensor > Length sensor > Incline sensor > Wind velocity sensor > Battery voltage > Supporting force sensor > Winch winding sensor > Load sensor Operational errors are : > Boom outside of the angle range of the load capacity chart > Boom outside the working radius of the load capacity chart > Extension condition of the telescopic sections does not correspond to the load capacity chart > Control input word does not exist (possible external signals !).

4.2.8.2 ∫Short beep∫ Any error message, which do not directly lead to a shut down the crane movement via the LICCON overload sa> fety device, are reported by an acoustical signal ∫SHORT BEEP∫, in addition to the optical display . The SHORT BEEP∫ is a 0.1 second long beeping sound, which is repeated in two second intervals. Monitored errors are: > max.permissible wind velocity has been exceeded (only if wind velocity sensor is active) > max. supporting force has been exceeded, or the minimum supporting force has not been reached (only if supporting force monitor is active) > ∫CAUTION∫ > the crane works at 90% of its capacity . The ∫HORN∫ alarm has a higher priority, which means it is louder than the ∫SHORT BEEP∫.

4.4.1

Display of actual supporting force The monitored additional function ∫supporting force monitor™ constantly monitors the actual hydraulic pressure in all 4 support cylinders with a pressure sensor and calculates the supporting force in tons (t) for each outrigger. These supporting fores can be checked by the operator as needed, in the ∫crane sup> ported™ mode, or they are displayed automatically, in case a critical situation arises. The minimum and maximum values, which trigger the alarm, depend on the crane model and have been preprogrammed at the factory. The LICCON ∫SUPPORTING FORCE LIMIT VALUE MODIFICATION∫ program al> lows the operator to change these values, if necessary, to adapt them to his particular situation.

4.4.2

To program the maximum and minimum supporting force values Prerequisite to start the ∫SUPPORTING FORCE LIMIT VALUE MODIFICATION∫ program : > the crane must be supported during operation > the assembly switch may not be actuated. As an additional safety measure, this program also monitors the assembly switch. If assembly opera> tion is attempted, the program returns to the LICCON Operation view.

024114>00

By pressing the P3 key, the view of the ∫SUPPORTING FORCE LIMIT VALUE MODIFICATION∫ program appears. In the right window ((DISPLAY window) all current supporting force values are dis> played. If one or more of these values are below the adjusted minimum or above the adjusted maximum values, they are blinking. In the left window ( (EDIT window, the programmed maximum and mini> mum values are shown. Two double arrows show first to the DISPLAY window, the program therefore urns in the DISPLAY mode.

Any new value entered is checked by the LICCON safe load indicator for its validity and is then adopted directly by the LICCON Supporting force monitor, or rejected as an error value (either too large or too small). In the DISPLAY mode (OF8), the reaction of the LICCON supporting force monitor tot he altered valu> es can then be checked.

4.4.3

Notes In order to assure proper function of the LICCON Supporting force monitor, the outrigger cylinders may not be moved to ™block down∫ nor to ∫block up™. Being able to determine the value limits by himself enables the crane operator to use the LICCON Sup> porting force monitor as a pre>warning system. Example: When using the crane below a certain surface condition : > the maximum permissible supporting force = 50 t > the operator desires a pre>warning at 10% before the maximum permissible suppor> ting force has been reached, which means, > the programmed limit value should be maximum 45 t. Due to fraction in different directions and non>measurable transverse forces in the outrigger cylinder, it is possible, depending on the machine type, that measurement values can fluctuate up to ± 2% of the maximum load capacity of the crane. D A N G E R : The LICCON supporting force monitor is only an additional aid. It does not pre> vent crane overload! Under no circumstances may the LICCON supporting for> ce monitor be used to utilize the crane until it reaches its the tipping or stability limit!!

MAINTENANCE / SERVICING

021528>01

The maintenance work on the overload safety device LICCON are confined to checking: 1.

Cabling, which connects the various parts of the system. If a cable is damaged, it must be replaced immediately.

2.

Insulation of the length sensor cable and the cable guides. If the insulation is worn or the cable guides damaged, these parts must be replaced.

3.

Checking the hoisting limit switch for accessibility and function identification by ∫LICCON∫.

4.

The cable drum must have sufficient mechanical prestressing in order to function correctly.

5.

Checking the pressure absorber on the luffing ram and the connecting hoses for leaking oil.

6.

Checking whether the display of the main boom length corresponds to the actual boom length. Apart from eliminating the disturbances which are listed in the disturbance table and replacing defecti> ve mechanical parts and cable, no other maintenance or service work needs to be carried out.

LICCON ERROR DETECTION

024116>00

The LICCON system performs a self test right after it is turned on. First, it checks the connection between the microprocessor central unit (ZE) and the control and indicator unit (monitor). The monitor shows the view as shown on the upper left page. If the test shows no problems with the connection, it runs through a system test . If the system test passes, the view as shown on the lower left page appears.

If no error was found in the system test, the view, as shown on the upper left page appears on the monitor for a short time. Then the set up view appears, with the equipment figuration as was used during the last working cycle. This view also appears for a short time anytime you switch between the various LICCON programs.

The 7 segment indicator of the power supply unit displays the number ∫7∫ if no error is found. The microprocessor unit, installed to the right, shows the number ∫0∫,∫1∫, and/or ∫2∫, depending on the type of crane. An error was found if anything else appears on the display.

However, it is possible that errors arise on the LICCON during the starting procedure or during crane operation. Possible errors are divided into 3 error categories: 6.1 6.2 6.3

Initializing error System errors Application errors.

All 3 types of errors are recognized by the system and are displayed on the screen as a series of numbers or as text or on the 7 segment indicator of the central unit. This enables the crane operator to localize any arising errors and decide if he can eliminate the error himself or if he must call a LIEBHERR customer service representative. If LIEBHERR customer service must be called, you must supply the following information: > Type of crane > Crane serial number > Error number > Error text > Application conditions.

69

6.1

INITIALISING ERRORS

021525>01

Initialising errors are hardware errors which are detected during the self>test of the LICCON. The 7>segment display of the microprocessor central unit blinks and displays the error no. If possible the error is also displayed on the screen. Additional to the error no., the error text and a closer description of the error is displayed. If a hardware error arises during operation, e.g. ∫EPROM defective∫, first a system error is displayed and then a display appears on the screen. Fatal system error Error no.

00/0 Program no.

If the monitor is dark, see error diagram ∫Monitor error∫.

.

On the microprocessor central unit ∫E ∫ is displayed. If the LICCON is then switched off and restarted (5 minutes waiting>time between switching off and on), the in> itialisation error is displayed on the screen and on the display of the microprocessor central unit, e.g. on screen: ∫Error F: INCORRECT EPROM>TYPE ...........∫ In the display of the central display only the letter ∫F∫ appears. This display blinks. IMPORTANT: A waiting>time of 5 secs. must be adhered to between switching the LICCON off and on. An error which can only be partially attributed to the initialisation errors is a defective connection between mo> nitor and microprocessor central unit (ZE). When switching the LICCON on the connection between the moni> tor to central unit (ZE) is checked first. If this connection is defective, the message ∫Data line failure∫ is displayed on the monitor. If the connection is in order, the following message is displayed on the monitor: ∫Data Line Check Passed OK!∫

Application errors are errors which can arise during crane operation due to external influences. The error numbers appear in the FK symbol ∫ERROR∫ via the F8 function key in the set up view or via F6 in the operation and telescoping view. The crane functions are continuously monitored by the following sensors. > Hoist limit switch > Length sensor > Angle sensor > Pressure sensor. The limits of the sensor are monitored by several programs in the micro processor central unit for the following limit errors: > Broken wire > Short circuit after ( > ) ground > Short circuit after (+) system voltage. The following application errors are differentiated: > Error due to technical defect > Error due to crane operation > Error due to external influences Errors, which occur due to crane operation, are differentiated: a) Errors , which are dangerous for the operation of the crane and lead to shut down. The shut off is always indicated by the shut off symbol . b) Errors, where the permitted limits for operation of the crane are being exceeded. The crane operator is warned, however, the system is not shut down. With exception of Error No. 000, an acoustical signal sounds for any error message, this acoustical signal can be turned off with the corresponding function key. CAUTION:

> > > >

There are three dangerous operating conditions,which are indicated by a blinking warning symbols, but without an Error No.

Elimination of the overload con> dition depends how the overload situation occurred and elimina> tion must be decided by the cra> ne operator according to each in> dividual situation. Basically, it is only permitted to use that cra> ne movement bypassing the overload safety device, which counters the movement which led to overload cut off . Some measures are: a) Lower load with hoisting ge> ar. b) By releasing the luffing mo> vement via the additional switch on left arm rest and therefore reducing the load momentum. c) By retracting the telescopic section and simultaneously luffing , the load momentum can be reduced. This move> ment however, depends on the type of crane

If possible, set operating mode and set up configuration to a more favorable load capacity chart, otherwise discontinue crane operation. If necessary, take down crane.
