Length sensor for Grove LG152/352

The length sensor, part number 9333101961, is an electronic component used to measure the extension of the telescopic boom on Grove cranes. This sensor integrates with the LG152/352 slipring assembly, which features a 2-core configuration for electrical signal transmission. By tracking the boom length, the sensor provides necessary input for the crane's load moment indicator (LMI) and safety systems to determine the safe lifting capacity during operation.

This component is engineered for compatibility with Grove machinery utilizing the specified LG152/352 slipring systems. It functions as a position transducer, often utilizing a cable-actuated mechanism to monitor the physical extension of the boom sections. The 2-core slipring allows the sensor to transmit electrical signals from the moving boom sections to the crane's stationary control systems without cable interference or entanglement.

Length sensors serve as critical inputs for crane safety systems. By providing continuous, real-time measurements of the boom's extension, they allow the LMI to calculate the current load moment accurately. This data ensures that the operator receives correct information regarding the crane's stability and lifting limits, which is necessary for maintaining safe operation within the machine's load chart parameters.
