Abstract: According to the structure and performance characteristics of the Underground Shovel Plate Carrier used in the coal mine, an U-shaped arrangement of vehicle hydraulic winch was designed in the paper. Under the control of the driving unit which integrated by the rotary reducer and the POSI-STOP type anti-drag locking device, the vehicle hydraulic winch which driven by the Underground Shovel Plate Carrier's hydraulic system could transfer power to the lateral arrangement transmission reducer. Meanwhile, through the application of a new type material rope which made by the UHMWPE (ultra high molecular weight polyethylene)and aramid fiber, the inapplicability and the insecurity problems of steel wire rope used in the situation of small curvature radius roller were solved fundamentally. In order to acquire technical parameters of the vehicle hydraulic winch, the dynamometer tests under various sustained load were carried out though the hydraulic test bed and the transmission test bed. As a result, the structural correctness of the hydraulic winch's design and the thermal equilibrium of each element were proved.
