Drum hoists are the simplest and most widely used motorized hoists. They are usually a dead haul type of hoist, where the entire load is supported by the hoist, without the use of counterweights.

The hoist has a drum long enough to accommodate all of the lift lines required for that particular set. The drum is helically grooved so that the lift lines wrap neatly in a single layer, to avoid damage to the wire rope. The drum can be oriented either horizontal or vertical depending on project requirements.
Drum hoists can be located on the grid, galleries, or in a separate motor room. A head block and loft blocks may be used to route the lift lines to the batten.
Fixed and variable speeds are available.
The motor, brake, and gearbox are an integrated unit from a single manufacturer, for quality assurance. A continuous shaft links the brake, motor armature, and the first stage pinion gear without the need for couplings, for added reliability and safety.
The motor brake is spring applied and electrically released, for "fail safe" operation.
The drum is helically grooved to carry a single layer of cable, for long cable life and reliable operation.
Four limit switches are provided for normal end of travel and over travel protection. The two circuits operate separately for added safety.
