INI Invention patent hydraulic free fall winch
- Product Structure
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.
- Main Features
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
- Application
compaction machine, pipe layers, crawler cranes, vehicle cranes, grab bucket cranes, crushers and so on
- Specification (can be revised to meet customer's specific needs.)
Features
1 Heavy duty high torque hydraulic motor.
2 Extremely watertight with good quality internal seal.
3 Free spooling clutch-Rotation (normal manual clutch).
4 Compact structure, easy for mounting by two angle bar.
5 Fast line speed provide high efficiency for recovery
6 With cable tensioner
7 Integrated mechanical brake.
8 Winch can be mounted on wrecker, recovery truck, or other vehicles
