The winch is powered by a hydraulic motor and drives the drum through a planetary reducer. It winds a steel wire rope to drive heavy objects, achieving traction and lifting of heavy objects. It has the characteristics of large power to volume ratio, good stability, low noise, high efficiency, long service life, easy commutation, stepless speed regulation, easy automation control, and overload protection. It is suitable for oil fields, coal mines, ports, geological drilling, mining, and explosive and flammable gas locations.Technical characteristics

1) The hydraulic motor, planetary reducer, and drum body of this winch are coaxial connected structures. Simple and compact structure, easy to maintain2) This winch adopts Italian technology, and the hydraulic motor is an imported radial swing plug motor from Italy. It has high transmission torque, high efficiency, compact structure, long service life, and high reliability3) This winch adopts a planetary reducer, with a compact structure, large bearing capacity, and high accuracy and efficiency. The gearbox is equipped with a normally closed wet pad hydraulic brake, which is connected to the control oil circuit. The opening/closing of the brake is associated with the start/stop of the motor, making the control automatic and convenient4) This winch integrates the directional valve, street valve, pressure gauge, inlet/outlet, and other components onto the hydraulic motor. Users only need to equip the pump station and hydraulic pipeline, simplifying the hydraulic system and improving the reliability of the transmission device, making it easy to operate and control.5) The directional valve of this winch is a self resetting proportional directional valve, which can accurately control the speed of the motor while ensuring safety6) The lifting oil circuit of this winch is equipped with a balance valve, which ensures stable and controllable lifting and unloading of heavy objects by the hydraulic winch, playing a buffering and pressure maintaining role. Even in special working conditions such as pipeline explosion and brake failure, there will be no sudden stall and descent, ensuring safetyThis winch adopts a balance valve imported from the United States, combined with the volumetric efficiency characteristics of hydraulic motors, to solve the problems of secondary sliding and empty hook shaking that commonly occur in winches
