Length transmitter for Liebherr LTM-1090-2

The length transmitter 571251408 acts as a sensor within the crane control system to track the extension of the telescopic boom. By monitoring the boom position, it supplies the necessary feedback to the Load Moment Indicator (LMI) system, which calculates safe load capacities and operating radii based on the current boom configuration.

This component is compatible with the Liebherr LTM-1090-2 all-terrain crane. It is designed to integrate with the crane's existing electronic architecture to ensure accurate monitoring of boom length during lifting tasks.

Length transmitters in heavy machinery typically function as cable-encoder or linear potentiometer devices. They convert the physical extension of the boom sections into an electrical signal that the crane's computer interprets. Consistent and accurate position data is required for the LMI to maintain safe operating parameters and prevent overloading the crane structure.
