Free fall winch is our patent product.
This series hydraulic winches consist of planetary gearbox, hydraulic motor, wet type brake, valve block, drum, frame and hydraulic control clutch.
The winches can get two speed if fitted with variable displacement hydraulic motor.
When fitted with hydraulic axial piston motor, the working pressure and power can be greatly improved.
The final stage of the series is fitted with a hydraulic clutch to get free fall function when the hook is empty. So the working efficiency can be improved.
1. Safe and reliable performance
2. high starting& working efficiency
3. Reliable operation with little noise
4. long lifetime
5. Low maintenance relieves your anxiety
