摘要

PROBLEM TO BE SOLVED: To provide a detection device for derailment of a crop car and the occurrence of wire trouble which can predetect derailment of a crop car and the occurrence of wire trouble.SOLUTION: The detection device for derailment of a crop car and the occurrence of wire trouble is installed in a crop discharger of a tilt hoisting system which hoists a plurality of wires connected to a crop car and moves the crop car along an inclined plane, and has a load cell which detects a load applied onto a wire sheave for hoisting each wire thereby detecting a hoisting state of the wire, and a control device which detects whether an abnormality occurs or not in hoisting of the wire on the basis of a difference load between the load cells provided in the plurality of wire sheaves.SELECTED DRAWING: Figure 1
