INTRODUCTION The information on this document could be subject to change without notice. The constructor is not responsible for possible content mistakes or misprints that could be present in this manual. Any reproduction, translation or copy of parts of this manual is forbidden without prior written authorization by The constructor. .

WARNINGS The load limiting device, is an electronic control device, designed to help the operator in the safe use of the machine, warning him by means of visual and audible alarms when approaching a dangerous condition. However, this device won’t replace the good experience of the operator in the proper use of the crane. The responsibility of the operations in safety conditions of the machine is on operator care, as well as the fulfilment of all safety rules prescribed. The operator must be able to recognize if the data transmitted by the system is correct and coherent with the real conditions. He also must be able to utilize the data in order to operate in safe conditions. The limiter is an electronic device with several components and could be subject to failures or defects. The operator must recognize these events and must act consequently (to proceed to repair, if possible, or to call the constructor assistance). Before starting the operations with the machine, user must fully read and understand this manual and follow the instructions written in it.

IMPORTANT NOTES The limiter has a powerful FAIL-SAFE self-diagnostics program suitable to verify the good operation of its circuits and measuring transducers. In case of a failure is detected, the limiter puts itself in emergency status by blocking the manoeuvres. Nevertheless, the operator, before starting the operation of the machine, must secure that the limiter functions correctly. To do this, he must verify the accuracy of the displayed values by performing some tests. He must also verify that there are not messages or alarm indications, and verify the correct operation of shut down function. Generally, the limiter does not automatically change the operating conditions of the machine (tables). The operator is responsible for the proper setting of the operating conditions of the machine and the correct use of the device

About this, follow the indications given forwards in the manual and concerning the operating modes. An incorrect setting of the tables can cause an incorrect operation of the limiter , will create a dangerous situation in the crane operating.

For this reason it is essential to set the correct operating mode.

These operating conditions generally vary when: a) outriggers are extended or retracted. b) switching, the operation from outrigger mode to on tires mode. c) further equipment (jib, ext, etc.) are installed or not. d) the number of parts of line is properly selected.

In general, it is mandatory to follow the instructions given by the crane manufacturer.

SYSTEM OPERATION DESCRIPTION The Load Limiting Device is designed to aid the operator in safefunctions of the crane. The limiter compares automatically the lifted load to the maximum one supplied by load table providing the necessary information to the user in order to work in safety condition.

The main readings are:

- actual lifted load - maximum admitted load - tilting percentage - operating radius - boom angle - boom extension (length) - working mode ( Operating mode) - warning lights (green, yellow, red) and audible alarm

The system determines the lifted load by computing it from the relevant sensing devices signals (pressure or load cell), and by means of the measures of boom angle and extension operating radius is computed too. The lifted load is continuously compared with the maximum allowable load obtained from the load tables.

Consequently three possible situations can occur:

Safety :

green lamp is on, no presence of acoustic signal : lifted load is lower than 90% of the maximum load.

Warning:

yellow lamp is on and audible alarm intermittently sounds; this is the warning situation. The signal occurs when the lifted load is more than 90% and less than 100% of maximum load.

Alarm:

red lamp is on and audible alarm sound continuously: lifted load exceeds the allowable load so that the control functions shut down is activated. In the alarm situation, only control function operations to allow the machine in a safe working condition are enabled.
