Electric hoists may be used as stand-alone equipment or mounted structural frames and tracks as a part of a lifting system. These types of lifting systems are:
Engine Hoists
Engine hoists, or engine cranes, are used to assist the workers in the installation and maintenance of engines of automobiles. They are designed to lift the engine under the automobile hood. Their electric hoists are mounted on top of the rigid and portable structural frame. The structural frame has wheels installed at its base to easily maneuver the hoist over the automobile, as well as to transport it around the machine shop. Its portability makes it suitable for outdoor applications. The structural frame of some engine hoists is foldable, so it can save space when it is stored.
Jib Cranes
A jib crane has a lifting fixture that primarily consists of two large beams constructed to form a cantilever. The mast, or pillar, is the vertical beam of the fixture that supports the reach. The reach, or boom, is the horizontal beam of the fixture wherein the electric hoist travels to position the load. There are three types of jib cranes:
Wall-Mounted Jib Cranes
Wall-mounted jib cranes are mounted on a wall or columns that are structurally rigid to support them. The rotation of their reach is limited to 2000. There are two types of wall-mounted jib cranes. Cantilever wall-mounted jib cranes offer the greatest amount of clearance above and below the boom and exert less force on the building column. Tie-rod supported wall-mounted jib cranes are supported using a wall bracket and a tie rod. Since there is no support structure under the boom, the electric hoist is allowed to travel fully along the length of the reach.
