Length sensor for Grove cranes

The length sensor 9333101617 serves as a precision electronic component within the control systems of Grove cranes. It functions by measuring the extension of the telescopic boom, providing data that is processed by the load moment indicator and overload protection systems. This information allows the crane control system to calculate the safe lifting capacity based on the current configuration of the boom. The assembly integrates a printed circuit board with a potentiometer, which converts the linear movement of the boom into an electrical signal proportional to its length.

This component is compatible with various Grove telescopic crane models. It is manufactured by Grove and is designed to provide accurate feedback to the crane's onboard computer to ensure operational parameters remain within safe limits.

In telescopic crane systems, length sensors are used to monitor the physical position of the boom sections. By translating mechanical extension into an electrical resistance change, these sensors provide the necessary input for the crane's safety systems to determine the load chart limits. Maintaining accurate sensor readings is a standard requirement for the safe operation of hydraulic lifting equipment.
