Length and angle transducer LWG 308 for Grove

The LWG 308 length and angle transducer, part number 9333103306, serves as a sensor within the control and safety systems of Grove cranes. It functions by measuring the extension length of the boom and its current angle of inclination. This data is transmitted to the load moment indicator system, which uses these inputs to calculate the safe lifting capacity of the machine in real time to assist in preventing overloads and maintaining operational stability.

This component is designed for integration into Grove mobile cranes. It utilizes internal mechanisms, such as a retractable cable for linear position sensing and an encoder or potentiometer for angle detection, to track the geometry of the boom assembly. Regular calibration and maintenance of this sensor are necessary to ensure the accuracy of the load calculations provided to the operator.

Length and angle transducers are used in heavy machinery to provide continuous feedback on the position of the boom. By converting physical movement into electrical signals, these sensors allow the crane control system to monitor the configuration of the boom at all times, which is a requirement for the proper function of safety limiters and load monitoring software.
