Worm gear winch 2,000 – 7,500 kg

The worm gear winch with a load capacity of 2,000 to 7,500 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. A second drive shaft on these hand rope winches also offers the user two speeds.

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
  • A second drive shaft enables work at two speeds
  • 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
