Hydraulic winch

摘要

A hydraulic winch (1) in which a piston rod of a brake cylinder (11) constituting a hydraulic winch (1) is connected in a state capable of being moved only in a range fixedly controlled in axial and diametral directions relative to a pressure plate (10) to control an axial movement of the piston (11P) alone when a mode is switched and not to exert an unreasonable load to the connected portion. Thereby, it is possible to prevent an overstroke of the piston (11P) of the brake cylinder (11) and to improve the switching responsiveness when switched to the brake release state again. <IMAGE>
