Hydraulic Winch PDA Series

We have been manufacturing this type of PDA series planetary winches for more than ten years, these PDA hydraulic winches feature is as below:

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-stan- dards 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.
