Gebuwin "WW-D-FS / WW-D-FSB" Free Spool Hand Operated Worm Gear Winch, Range from 2000kg to 5000kg

The Gebuwin range of hand driven worm gear winches are known for their robust construction. This range of winches are used for both hoisting and pulling of loads. These worm gear winches are equipped with a cable drum free spool, making it possible for the cable to be easily pulled from the drum, due to the fact that the cable drum can be detached from the transmission.

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. As well as this, these winches can be mounted in such a way that allows for the cable to come free from the winch horizontally.

The listed capacities refer to the hoisting capacities which are calculated according to the first cable layer on the cable drum. In the case of these winches being used for the pulling of loads, the hoisting capacity should be multiplied roughly by a factor of 2.5.

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 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 and the restraint is divided over two systems. 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 2000kg 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
