AI Technical Summary

Technical Problem

Existing detection devices have unreasonable detection methods for the extension length of movable outriggers, resulting in low reliability and failing to meet the requirements of high reliability in working scenarios.

Method used

The system employs a pull-wire detection component and redundant detection components, including a pull-wire sensor, multiple detection plates, and a position sensor, to detect the extension of the movable outrigger in real time through multiple methods, ensuring that the extension can be accurately obtained even if one detection method fails.

Benefits of technology

Redundant detection of the extension of the movable outriggers is achieved, which improves the reliability and accuracy of the detection and is suitable for working scenarios with high reliability requirements.
