Drum-type winches

Drum-type winches are mechanisms for moving loads in a horizontal plane. The design includes a reducer (worm or gear type) and a drum onto which a wire rope or strap is wound. Drum-type winches are also used as additional equipment on vehicles.

Design features

Worm-gear drum-type winches are widely used thanks to their simplified drum-stopping mechanism, which improves operational safety. The reliability of the design and the mounting method allow the mechanism to be fixed to a stationary element.

Disadvantages of worm-gear drum-type winches: large dimensions, reduced load-moving capacity, and more complex operation.

Gear-type drum winches have a simplified design and are easier to repair. A high-reliability ratchet is used to secure the wire rope. The reducer of these models is easier to maintain. The disadvantage is the difficulty of winding the wire rope due to the risk of the strap or flexible element getting into the reducer housing. The smaller drum diameter reduces the winding speed of the wire rope and increases its bending, which accelerates wear of the rigging element.

Selection

The choice depends on operating conditions and tasks. Drum-type winches are used in garage conditions or as stationary installations. Worm-gear models are suitable for open terrain, for example when towing a stuck vehicle.

The operating load on the wire rope and other structural elements of the winch must not be exceeded.
