- The drum is supplied as standard non-grooved, can however be supplied grooved (see Ill. 3-6) All drums have two cable fixtures.
- Twin-cable, non-grooved designs as shown in Ill. 3 - 7 available.
Both cables are attached to the same drum flanged pulley and are wound from that point parallel onto the other flanged pulley. On this drum grooving arrangement the cable can only be wound on in the layer No.1. If two cable layers are required, the grooving should be in accordance with Ill. 5 and 6.
The cable is attached at the centre of the drum. From there the two strands in the first layer are wound onto the two flanged pulleys. In the case of the 2nd cable layer, the two strands run back from the flanged pulleys to the drum centre.
A separation bar located at the centre of the drum can be fitted for larger cable take-ups on twin-cable operation.
Additional special designs
- Winches are also available for special applications where opposite turning direction is required i.e. the direction of rotation for “lifting” is not clockwise but anti-clockwise. The cable is then also wound on the opposite side.
