Hoists are used on construction sites to vertically transport materials and/or passengers. They are most commonly powered by diesel engines or electric motors that rotate a drum around which a wire rope is wound. Hoists may also be hydraulically powered, and may use chains as the lifting mechanism rather than wire rope.
The landing area must be fitted with some form of guard, usually sliding gates, and the base of the hoist, where the winch is situated, should be well guarded to prevent injury. There must be a risk assessment undertaken prior to hoisting, and subsequent lifting operations should be properly planned and carried out in accordance with the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER).
Hoists differ from cranes in that cranes move items vertically and horizontally. Hoists differ from lifts in that they are generally used for industrial purposes and are not publicly accessible. Winches are typically used to pull or drag items along level surfaces, rather than lifting them vertically.
Mobile hoists are commonly found on construction sites, and are capable of lifting material loads to heights of up to 30 m. They are designed to be dismantled, folded onto the chassis and moved to another location with relative ease, either under their own power or towed by a haulage vehicle.
The mast and winch unit is mounted on a platform, typically with a load capacity of 500 kg. This is then stabilised using jacks or outriggers. Extending upwards, a lattice hoist mast is constructed to which sections can be added depending on the height required, together with tie supports fixed to scaffolding or the building frame. A protective screen is placed around the hoist mast, fitted with gates at least 2 m high at all landing levels.
These are designed to lift passengers, although they can also be used for materials as long as the weight is kept within the loading capacity. The type of hoist can vary from a single cage with rope suspension to twin cages with rack and pinion operation mounted on two sides of a static tower. They are usually controlled from within the cage, and there must be additional safety devices to prevent over-run or free-fall.
A typical passenger hoist cage is 2.7 m high and capable of carrying 12 passengers at a total weight of 1,000 kg. Typical speeds are 40-100 m/min. The hoist tower is generally assembled from 1.5 m-long sections and tied at 12 m centres to the face of the structure.
