チの制御装置。[Scope of Claim for Utility Model Registration] A wire rope that is pulled out from a hydraulic winch that is driven and controlled by a manually operable hydraulic control device and passes through the telescopic boom end, attaches a hook to the telescopic boom end directly or through a jib. A control device for a winch in a suspended telescopic boom type crane, comprising: a selection switch; a rope length sensor that detects the amount of extension and contraction of the wire rope from the winch; a boom length sensor that detects the amount of extension and contraction of the telescoping boom; receiving signals from a selection switch, the rope length sensor, and the boom length sensor;
A signal corresponding to the amount of expansion and contraction of the telescopic boom detected by the boom length sensor and a signal corresponding to the amount of expansion and contraction of the wire rope detected by the rope length sensor are compared, and the amount of expansion and contraction of the telescoping boom and the amount of expansion and contraction of the wire rope are determined to be the same. 1. A winch control device for a telescopic boom type crane, characterized in that the winch control device comprises a calculation unit that issues a control signal to the winch hydraulic control device so that the following is achieved.
