AI Technical Summary

Technical Problem

In existing fork grounding control systems, insufficient grounding can lead to continuous high tension in the cable used for raising and lowering forks, causing potential damage.

Method used

A loading and unloading machine with a cable tension detection system that issues warnings or automatically adjusts the fork position to maintain tension below a threshold, ensuring the cable is not overstretched during rest or idle states.

Benefits of technology

Reduces cable tension during rest, thereby extending the lifespan of the cable and preventing damage.

Abstract

To provide a cargo handling machine capable of loosening a tension acting on a funicular body in a resting condition.SOLUTION: A cargo handling machine (100) is one which transmits power for elevating to a fork (104) via a funicular body (113). An operation control or an operation supporting control is performed to lower the fork (104) so that the tension on the funicular body (113) is equal to or less than a threshold in the resting posture with the fork (104) grounded.SELECTED DRAWING: Figure 1
