Gebuwin "WW Series" Hand Operated Worm Gear Winch, Range from 250kg to 1500kg

Worm gear hand winch, with single or double drum. Optional painted/zinc plated finish and Atex rating.

Model: 

WW / GHOW-4752


The Gebuwin range of hand driven worm gear winches are known for their robust construction. The hoisting capacities are calculated according to the first cable layer on the cable drum.

The worm gear winches are more safe than the spur gear winches, due to the fact that 50% of the braking is done by the friction loss in the transmission. Subsequently, the load on the pressure brake is greatly reduced. Due to the higher friction loss in the transmission, the worm gear winches have a lower performance efficiency than the spur gear winches.

All of the worm gear winches are equipped with a load pressure brake. This brake holds the load at any required height during hoisting and lowering. The winches have a static safety factor of  minimum 4. The cranks can be adjusted in length and are recoil-free. All rotating parts run in maintenance free bearings. From the 2000 kg capacity winch and up, the winches are fitted with a second drive shaft, which makes it possible to work with two speeds. Most parts are made from steel and have been either painted or zinc plated.

Product Features

  • Robust construction.
  • Primarily used for hoisting, also possible for pulling loads.
  • The braking mechanism consists of 50% by the friction in the worm gear transmission and 50% by a load pressure brake.
  • Static safety minimum factor 4.
  • Adjustable crank and recoil free.
  • All rotating parts run in maintenance free bearings.
  • Easy to grease worm-worm wheel transmission.
  • The numbers in the product name correspond with the hoisting capacities on the first cable layer.
  • Pulling capacity is approx. 2.5 times the hoisting capacity.
  • Cable outlet possible upward, downward and at rear.
  • Standard paint finish in grey RAL 7035 (Winch) and black RAL 9005 (Drum) according to DIN 12944, C1M.
  • WW1000 and WW1500 are suitable to be used with winch power tool AM5000.
  • Also available with grooved drum, twin drum, Zinc plated (6-8 micron) finish and ATEX certified, or with a slipping crank to limit a maximum load.
