This type of hydraulic winch is composed of a variety of flow apparatus, XHBD double speed hydraulic motor, flake wet brakes, planetary reducer drum, rack and other components, consisting of one way or two way balance valve( United States import) and control brake with high pressure shuttle valve. The user is only equipped with pump station and reversing valve. However, because the winch has its own valve set, it not only simplifies the hydraulic system, but also improves the reliability of the transmission device. This type of hydraulic winch has successfully solved the two technical problems of air hook jitter and lifting in the general hydraulic winch. This type of hydraulic winch is quite balanced in the operation of lifting and lowering. At the same time, a fast to slow switching can be realized by the way of an external oil control road, with high operating and working time, less energy consumption and noise. Low sound, compact size, beautiful appearance, good economy and so on, can be widely used in railway and automobile crane, ship, oil field, coal mine, port and other lifting equipment.
