Load cell for Liebherr LTM1400

The load cell, part number 100-060-071-741, functions as an electronic transducer that measures the force or weight applied to the crane and converts it into an electrical signal. Within the Liebherr LTM1400, this component is integrated into the crane's safety and overload control systems. By providing real-time data on the weight being hoisted, it allows the control system to calculate the load moment and alert the operator to potential instability or capacity limit violations during lifting operations.

This specific 170-ton unit, designated as 01 KMD, is engineered for fitment on the Liebherr LTM1400 all-terrain crane. It is typically installed at critical structural points, such as the boom cable anchorage or the hook attachment point, to monitor the mechanical stress exerted on the equipment. The sensor utilizes internal strain gauges that change electrical resistance when deformed under load, providing the precise feedback required for the crane's onboard management system.

In heavy machinery, load cells serve as the primary input for safety systems that prevent structural failure. By continuously monitoring the tension or compression forces acting on the boom and rigging, these sensors ensure that the crane operates within its load chart parameters. Proper calibration and monitoring of these sensors are necessary to maintain the accuracy of the crane's safety indicators.
