The Gebuwin range of hand driven worm gear winches are known for their robust construction. The listed capacities refer to the hoisting capacities which are calculated according to the first cable layer on the cable drum.
The winches are equipped with a load pressure brake. This brake holds the load at any required height during hoisting and lowering. 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
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. The winch with 7500 kg capacity has the worm-worm gear transmission completely protected by a sealed cover.
As an extra option, it is possible to have an adjustable slipping brake on the cable drum which allows for a controlled release of the cable.
