A hydraulic winch is a type of winch that operates a hydraulic motor directly or through a reduction gearbox. When using the analogy method, the design pressure of the actuator is extracted according to the type of the host. . The pneumatic winch needs to be equipped with a compressed air station: the pneumatic system has a lower working pressure, the air motor has a larger outer shape, and the overall weight of the pneumatic system is heavier; it is sensitive to the premise of the situation. In a low temperature environment, there may be moisture condensation. In pneumatic piping and components; noise muffler is required for noise. In the measurement technique, the line speed and the retracting distance of the cable are tested by using the proximity sensor and the optical encoder, and the line tension of the cable is measured by a strain gauge installed on the axle of the winch pulley, and the above information is received and applied through the pc and the plc. The electric proportional pumping system controls the displacement and pressure of the hydraulic pump and hydraulic motor.
