Worm gear winch 250 – 1,500 kg
The worm gear winch with a load capacity of 250 to 1,500 kg has a gear unit consisting of a worm shaft and a wheel. Due to the fact that this gear causes friction losses, it already delivers 50% of the braking effect. The load pressure brake delivers the other 50%. The combination of braking system and robust design results in a very safe manual hoisting and pulling winch.
Product features:
- Robust construction
- Mainly used for lifting, including pulling loads
- The braking mechanism consists of 50% friction in the worm gear and 50% a load pressure brake
- Static minimum safety factor 4
- Adjustable and recoil-free crank
- All rotating parts run in maintenance-free bearings
- The numbers in the product name correspond to the lifting capacities on the first cable layer
- The pulling force is approx. 2.5 times the lifting capacity
- Cable exit up, down and back possible
- Standard paint in gray (RAL 7035) and black (RAL 9005) according to DIN 12944, C1M
