AI Technical Summary

Technical Problem

Existing technologies cannot effectively identify and reduce the lateral bending and deflection of the crane boom, which leads to the risk of the crane boom bending to the left, bending to the right, tilting upwards or downwards during the extension and retraction process, affecting safety.

Method used

By acquiring the state parameters of the operating machinery, the lateral bending and deflection of the crane boom are identified using encoders and tilt sensors. The current of the winches is adjusted through a PID adaptive intelligent algorithm, and the current of the first and second winches is controlled in real time to reduce the lateral bending and deflection of the crane boom.

Benefits of technology

It enables real-time identification and adjustment of lateral bending and deflection of the crane boom, reducing the risk of lateral bending and deflection of the crane boom and improving the safety of the crane boom.
