Hoist atop an elevator. 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, fiber or wire rope as its lifting medium.
Chain hoists are ceiling-mounted engine cranes that are often slower than hydraulic hoists and electric chain hoists. [4] Chain hoists utilize a system of gears and chains to multiply forces that are produced when the operator is pulling the chain to lift the engine. A braking system prevents the engine from unintentionally lowering by the user ...
A jack which can lift a mobile home. A jack is a mechanical lifting device used to apply great forces or lift heavy loads. A mechanical jack employs a screw thread for lifting heavy equipment. A hydraulic jack uses hydraulic power. [1] The most common form is a car jack, floor jack or garage jack, which lifts vehicles so that maintenance can be ...
Some portable gantry cranes are equipped with an enclosed track, while others use an I-beam, or other extruded shapes, for the running surface. Most workstation gantry cranes are intended to be stationary when loaded, and mobile when unloaded. Workstation Gantry Cranes can be outfitted with either a wire rope hoist or a lower capacity chain hoist.
Cranes provide less flexibility in movement than industrial trucks because they only can operate within a restricted area, though some can operate on a portable base. Most cranes utilize trolley-and-tracks for horizontal movement and hoists for vertical movement, although manipulators can be used if precise positioning of the load is required.
Such systems operate between 4,000 to 5,800 psi (28,000 to 40,000 kPa). The North American market developed low pressure / high volume systems, which allowed operators to share the hoist's hydraulic system with other hydraulically powered devices. These systems typically operate with a larger gear pump and larger hydraulic reservoir. Operating ...
