  • Product Structure

This series of hydraulic winches are composed of a planetary gearbox, hydraulic motor, wet-type brake, valve block, drum, frame, and hydraulic control clutch. The system allows for two-speed operation when equipped with a variable displacement hydraulic motor. When fitted with a hydraulic axial piston motor, the working pressure and power can be significantly enhanced. The final stage includes a hydraulic clutch to enable free fall functionality when the hook is empty, improving overall efficiency.

  • Main Features

1. Compact design, easy to install

2. High starting and working efficiency

3. Reliable operation with minimal noise

4. Long service life

5. Low maintenance requirements

6. Cost-effective solution

  • Application

Used in compactors, pipe layers, crawler cranes, vehicle cranes, grab bucket cranes, crushers, and more. These winches are widely applied in construction equipment, mining industry, deck machinery, truck cranes, and other light, medium, and heavy-duty applications.
