Worm gear winch 2,000 – 5,000 kg with overrunning clutch

These worm gear winches with a load capacity of 2,000 to 5,000 kg have a gearbox 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.

The special feature of this design is the additional overrunning clutch, which makes it possible to detach the drum from the gearbox in order to unwind the (wire) rope from the rope winch without resistance.

Product features:

  • Robust construction
  • Primarily used for pulling
  • One-way clutch on the rope drum to pull the rope from the winch by hand
  • 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
