 Hydraulic winches manufacturer-Ningbo Bonny Hydraulics Transmission Co.,Ltd

we are hydraulic winches manufacturer and we have set up hydraulic winch research team specialised in manufacturing all kinds of hydraulic winches to meed different industries request.

We currently have hydraulic hoisting winch,hydraulic pulling winch,recovery winch,truch winch,4X4 winch,free fall hydraulic winch.

Our hydraulic winches are widely applied in drilling rig,mobile crusher,mobile crane,excavator,bulldozer,marine ship,off-shore crane etc machinery area.

Our winches have been exporting to Australia,German,Swithertland,Polland,Singapore,etcs.

We have 30 patent and 80 kinds of products enjoy high reputation in the global market.

If you are interested in our hydraulic iwnches,please kindly contact with me.

With brake in the last stage, free fall hydraulic winch can realize the emergency rapid free fall function. Thus it is widely used in pipe layer, crawler crane, auto crane, engineering driller, grab windlass, gravity crusher and any other hoisting equipment.

Features:
1. One-or two-stage planetary gearboxes, smooth operation and reasonable structure.
2. Normally closed friction type brake, high braking torque, safe and reliable operating.
3. Small volume, compact structure and high transmission efficiency.
4. Radial piston hydraulic motor with long life operating.
5. Mounting frame is available on request.
6. Balance valve, shuttle valve, limit switch and other accessories are also available on request.
7. With brake in the last stage, it can realize the emergency rapid free fall function.

PRODUCT STRUCTURE

• 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 

• Compact design, easy to install

• high starting& working efficiency

• Reliable operation with little noise

• long lifetime

• Low maintenance relieves your anxiety

• cost saving

 APPLICATION

 • compaction machine, pipe layers, crawler cranes, vehicle cranes, grab bucket cranes, crushers and so on.
