dredger winch, marine winch, hydraulic winch, compact winch, mini crane winch, drilling rig hydraulic winch

We have been manufacturing planetary winches for more than ten years,this type of hydraulic iwnch are widly applied to crane and drilling rig.

Wide Range of Pulling Force
Hoisting application, line pull 13 kN to 650 kN. Controlled free fall application, line pull 6,5 kN to 325 kN.

Calculation according to FEM
The output torques T, is based on FEM-standards I and IX as well as DIN 15020. Load conditions L3,
running time classification T5, according drive unit group M5. Ambiant temperature + 20°C.

Gear tooth forms
Selected for optimum tooth flanks and root strength and also for minimum sliding velocity, as per DIN 3990. External gear teeth are case hardened and ground, internal gears are annealed and nitride hardened.

Bearings
All gearbox elements are fitted with anti-friction bearings, needle roller or cylindrical roller bearings for the planetary gearboxes.

We promise continuous improvement, always surpassing your expectations, and helping you to achieve greater heights of product performance. In short, all the benefits of a dynamic organization that you will be happy to work with.
Our HW series hydraulic winches in the following categories:
Hydraulic winches in the range of 6.5 KN to 325KN for lifting purpose with all components integrated in the winch except the rope under standard products.

We currently aid industrial and construction hoisting equipments like:

*Pick & carry cranes
*Truck mounted cranes.
*Self propelled cranes (crane hoists)
*Mining rigs
*Off shore drilling rigs
*Other assorted rigs

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.

Free fall brake
The free fall brake housing must be filled with hydraulic oil. In all applications, the circulation of hydraulic oil through the free fall brake housing is necessary. The circulating oil should be lead back to the reservoir without back pressure.
