The modular design of hydraulic winch series, by a hydraulic motor, multi-plate friction brake, planetary gear reducer, drum, and support other components to the overall form. Hydraulic winch comes with shuttle valve and balance valve, shuttle valve to control brake balance valve to prevent the winch both body weight and because of the whereabouts of the work, but also enhance the stability of the winch or fall, a unique groove design to ensure the level does not change chaos rope, providing the security. 
 Nitride hardened gears and ring gear of the winch used to ensure low noise operation, has an excellent load capacity and operational reliability, while an internal planetary gear installed in the drum, saving space, with a compact structure. Therefore, this series has a good start of, smooth operation, high efficiency, high carrying capacity, compact, low noise, easy to install and so on. Widely used in construction, petroleum, coal, geological drilling, marine ports, railways and other equipment
