Lifting equipment includes any equipment or machinery used at work for lifting or lowering loads or people, including accessories and attachments used for anchoring, fixing or supporting the equipment . There is a wide range of lifting equipment in the construction industry. A hoist: is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fibre or wire rope as its lifting medium. A crane: is a type of machine, generally equipped with a hoist, wire ropes or chains, and sheaves, that can be used to lift and lower heavy materials and to move them horizontally. Different types that can be found in construction are: A tower crane: is a balance crane that consists of the same basic parts.

Fixed to the ground on a concrete slab, tower cranes offer height and high lifting capacity. The base is then attached to the mast which gives the crane its height. Telescopic crane: has a boom that consists of a number of tubes fitted one inside the other. A powered mechanism extends or retracts the tubes to increase or decrease the total length of the boom. These types of booms are highly adaptable, are often truck mounted and used for short term construction projects. A mobile crane: is a cable-controlled crane mounted on crawlers or rubber-tired carriers or a hydraulic-powered crane with a telescoping boom mounted on truck-type carriers or as self-propelled models. They are designed to easily transport to a site and use with different types of load and cargo with little or no setup or assembly. All terrain crane: is a mobile, truck mounted crane with the necessary equipment to travel at speed on public roads, and on rough terrain at the job site using all-wheel and crab steering. They need little set-up and can travel with a load but are very heavy and cannot easily be moved from one job site to another.
