Axles The axles are welded of high-tensile grain refined structural steel and almost maintenance -free. 1st axle : single tyres, steerable, driven via planetary gears in the wheel hubs.
1.3.4
2nd axle
:
single tyres, steerable, driven via planetary gears in the wheel hubs, with through-drive, differential lock for longitudinal lock.
3rd axle
:
single tyres, steerable and non driven.
4th axle
:
single tyres, steerable, driven via planetary gears in the wheel hubs, with through-drive, differential lock for longitudinal lock.
5th axle
:
single tyres, non steerable, driven via planetary gears in the wheel hubs.
6th axle
:
single tyres, non steerable and non driven.
7th and 8th axle
:
single tyres, non steerable and non driven.
Cardan shafts All cardan shafts are maintenance-free with 70° diagonal toothing. Just 4 fixing screws enable a particularly faster mounting and dismounting.
1.3.5
Axle suspension with „Niveaumatik Suspension“ All axles are optimally directed by longitudinal and transverse pull rods. The axles are hydropneumatically suspended by hydraulic rams and vertically adjustable and hydraulically lockable. Due to the formation of axle pairs, the suspension of the axles, dependent on the travel condition, can be activated independent from one another or with axle equalization. The travel conditions suspension locked or activated are fixedprograms and are remote-controlled from the driver's cabin: Program 1.1 Serves for supporting the crane. All axles are locked. Pressure equalization exists only between both axles within the axle pairs 1+2, 3+4, 5+6 as well as 7+8. Program 1.2 Serves for travelling with equipment on even ground. All axles are locked, pressure equalization between all axles within the axle blocks 1-4 and 5-8. Program 2 Serves for road travel. The suspension of all axles is activated. In travel condition, the suspension range is: Tyres 14.00 R25: 150 mm upwards and 150 mm downwards Tyres 16.00 R25: 200 mm upwards and 100 mm downwards For the improvement of the fording ability, the entire carrier can be lifted. For the reduction of the overhead clearance, the entire carrier can be lowered. For travelling along slopes, the entire carrier can be inclined by +/- 9°. When cornering, the lateral stability of the vehicle is optimally assured by the hydropneumatic suspension.

BASIC CONCEPT OF THE LSB DATA BUS SYSTEM (LSB - Liebherr System Bus) 1 GENERAL The automotive industry employs increasingly bus systems in order to reduce manufacturing costs. Various users (actuators, sensors or other LSB users) are interconnected by a data line. This excludes cost intensive wiring work and reduces the number of plug-and-socket connections frequently liable to failures. Each bus user is provided with its own intelligence in form of a microcontroller. A communication between the individual users is realized by the bus.

address2
user 1 e.g. CU 0
user 2 e.g. angle sensor
transmitter receiver address3
user 3 e.g. length sensor
address4

user 4 e.g. hoist limit switch
The above fig. demonstrates the communication of the individual bus users by an example of a simplified bus circuitry. The switches represent the transmitter function, the lamps represent the receiver. Each user has its own address which is available just once within the system. The user 1 (CU0) has the address 1 and a master function, the user 2 (angle sensor) has the address 2, etc. A maximum of 30 users can be connected to the bus. The bus line is fed by a constant power source with 300 mA. Its object is to supply a limited current of 300 mA against frame in the event of a short circuit. In order to ensure that the individual users come to an understanding with one another, each of them should speak or understand the same language. In respect to the above example, this language could be the Morse alphabet. When the system is switched on, the power source receives 24 V and supplies the bus line. All receiver lamps light up. Each user is activated. The user 1 with the address 1 (master function) starts to address the user 2 by actuating its momentary-contact actuator by the Morse code. All users receive this message. The receiver lamps are flashing. User 2 recognizes that it is being addressed by decoding the message and returns its reply by actuating its momentary-contact actuator.

BASIC CONCEPT OF THE LSB DATA BUS SYSTEM The manner according to which the communication on the line takes place is defined by a transmission protocol according to which all users operate. When user 1 has received an answer from user 2 (software handshake), it can address another user or enable the bus for other users. In that case, user 1 switches itself into the listening mode and another user occupies the bus. The transmission speed adapts itself automatically to the user with the lowest transmission speed (baud rate). In practical operation, the lamp and switch are replaced by a power transistor and comparator in the bus interface circuit. The activation or evaluation of the bus signals is performed by a microcontroller which processes the TXD (transmitter) or RXD (receiver) signals of the bus interface circuit.

BASIC CONCEPT OF THE LSB DATA BUS SYSTEM 2 BUS INTERFACE
The bus interface circuit has been developed for 2-wire or 3-wire bus systems. The circuit is incorporated into the input board of the CUs as well as into every bus user. power supply +24V for 3-wire-system data line and +24V power supply for 2-wire-system data line frame 0(24)V

microcontroller for application
In case of the 2-wire system, the power supply of the application electronic (sensor) is performed by clocked bus signals. If the bus signal is ”high”, the current passes via the fuse F1, through the diode V1, to the storage capacitor C1. The capacitor is charged by the bus voltage (24V). By means of this voltage, the connected electronic modules can be fed. If the bus signal passes to ”low”, the diode prevents a discharge of the capacitor. The voltage divider R1, R2 determines the LOW threshold of the connected comparator, which transforms the digital bus signals into defined switch signals. The bus signal is always greater or smaller than the signal at the negative input of the comparator. The comparator is switching according to a defined manner and transmits this signal to the application electronic. The operating point of the ”low-high” transition is defined to 1/3 of the bus supply voltage. The switching hysteresis is between 1/3 and 2/3 of the bus voltage. The transmitter (TXD) consists only of a power transistor which is short-circuiting the bus signal against the frame. Since the bus is fed by a constant power source, a defined current of 2A passes via the transistor to the frame. The information, which is transmitted on the bus line, consists of a pulse train of highlow signals. All bus users connected are hearing this information simultaneously. If one of the bus users is defective, which would cause a short-circuit on the bus, the bus will not be operational. The application of 24V directly to the bus line causes the fuse F1 to respond. The defective user will be separated from the Bus. A new system start recognizes, that the defective user(s) do not respond and thus reacts application-controlled.

BASIC CONCEPT OF THE LSB DATA BUS SYSTEM 3 BUS PROTOCOL The serial data protocol, explained with the Morse code in the example, consists of a certain number of pulse trains in practical operation. The information is transmitted within a 10 bit wide data format, in the following referred to as character frame. Each frame starts with a start bit, followed by 8 data bits and ending with 1 stop bit. The users connected are synchronized by the break signal. The break signal consists of one start bit, the following 8 data bits and 1 stop bit are low. An attempt to synchronize the bus users can be recognized by an equal flicker of the bus LED on the input board (bus interface circuit). (The bus master is transmitting break characters). character frame

The communication on the LICCON system bus can take place by 7 different types of messages: 1. TRANSMISSION OF A COMMAND WITH ANSWER The master transmits a command and a data block of variable length to a slave. The slave executes that command and returns an answer 2. TRANSMISSION OF A COMMAND WITHOUT ANSWER The master transmits a command and a data block of variable length to a slave. The slave executes that command but does not return a confirmation (e.g. commands to all bus users) 3. INQUIRY WITH ANSWER The master transmits an inquiry to a slave and expects a certain answer. (this is specially designed for a quick scan of 1- or 16-bit sensors) 4. 1-BIT ANSWER The slave returns a 1-bit answer (e.g. hoist limit switch – lift top) 5. 16-BIT ANSWER The slave transmits a 16-bit answer (e.g. digitalized analog-value length sensor) 6. BLOCK ANSWER OF VARIABLE LENGTH The slave returns a data block of variable length to the master 7. SYNCHRONIZATION (BREAK SIGNAL) The master or the slave can transmit a BREAK signal in order to signalise an error during the communication. The running communication is terminated and all users are synchronized.

BASIC CONCEPT OF THE LSB DATA BUS SYSTEM The above schedule shows that a message can consist of different message types. Each message consists of protocol-, data- and check-sum frames. The shortest message consists of a protocol frame with 1-bit data and a check sum frame. The 1st protocol frame contains the address in bit 0 to 4, bit 5 to 7 contain the message type identifier. The following 2nd frame contains the statement of the consecutive data frames in bit 0..2, and bit 3 to 7 the function identifier of the message. Dependent on the type of message employed, a different number of frames is transmitted.
