圧シリンダの駆動装置。[Scope of Claim for Utility Model Registration] A supplementary jib that is attached to the tip of a telescoping boom that is attached to the swivel base of a crane so that it can be raised and lowered, particularly a hydraulic cylinder for tilting in a supplementary jib that can variably adjust the tilt angle with respect to the telescopic boom using a hydraulic cylinder for tilting. A drive device comprising: a hydraulic oil tank, a hydraulic pump, and a hydraulic pressure generating section including an internal combustion engine for driving the hydraulic pump; and a switching valve interposed between the hydraulic pressure generating section and the tilting hydraulic cylinder. In addition to being attached to the tip of the telescopic boom or the base of the extension jib,
Driving a hydraulic cylinder for tilting in a supplementary jib, characterized in that the switching valve is configured to be switched from the swivel base side by an electric cable that is freely wound up by being fed out to a cord winder or by wireless operation. Device.
