Abstracts: An overhead hoist is a type of crane where the hook and line mechanism runs along a horizontal beam that runs along two widely separated rails. Often it is in a factory building and runs along rails the building’s two long walls. An overhead crane typically consists of three important parts: 1. The hoist, providing up/down motion to lift items. 2. The trolley, providing left/right motion for the hoist and load. 3. The bridge, providing back/forward motion for trolley, hoist and load. This is permanently installed in a factory, shop, or warehouse to move items not moveable by humans or forklifts. The most common overhead hoist use is in the industry. Every step of steel, until it leaves a factory as s finished product, the steel is handled by an overhead hoist. Raw materials are poured into a furnace by hoist, hot steel is stored for cooling by an overhead hoist, the finished coils are lifted and loaded onto trucks and trains by overhead hoist, and the fabricator or stamper uses an overhead hoist to handle the steel in his factory. The automobile industry uses overhead hoist for handling of raw materials. Smaller workstation hoist handle lighter loads in a work-area, such as CNC mill or saw
