A hoist supplier is a company that assembles temporary hoists (construction elevators) used to lift construction materials or site personnel during a building's construction phase. It is not necessarily the manufacturer of the parts of the hoist. Construction hoists are often installed on the side of a building, outside of its footprint. However they can also be installed inside a structure, as long as the machinery is specific to the construction phase and is not simply a future elevator being used for construction.
