3.1. Function description
The WW type winches are drum winches with a worm gear transmission. The load is held at each required height by a built in load pressure brake. The worm
shaft and cable drum run on bearings. The housing is made of plate steel and is suitable for mounting on walls, masts and the like. The crank is adjustable in
length and detachable. The winches with hoisting loads of 2000, 3000, 4000, 5000 and 7500 kg are fitted with a second drive shaft with another transmission.
3.2. Mounting instructions
The winch must be mounted with the bolts as set out in the corresponding chart. To avoid tension build up in the winch housing, pay attention to the following:
- there must be a smooth surface at the mounting bolt position;
the wall or other construction must have sufficient carrying power;
-
the level of the mounted winch must be checked with a spirit level in order to ensure good cable movement.

All the nuts of the mounting bolts must be evenly fastened and secured.
3.3. Cable mounting
For the choice of cable, chart 1 must be consulted. The cable must run-off upwards from behind the drum. The cable is allowed to run-off backwards horizontally
from underneath the drum with the WW series as well as with some of the models in the TL series.
Be careful! The brake does not work in the case of an incorrect cable run-off.
The cable length must be of sufficient length to allow for 3 windings to remain on the drum when in the lowest position. The cable mounting is done by means of
the fixed cable clamp.
Be careful! If you use a Dyneema/HMPE cable, you must take into account 10 safety windings instead of 3.
