Builder's hoists facilitate vertical transportation of materials and personnel on construction sites. Consist of components like mast, platform, hoist motor, wire rope/chain, safety devices, and controls. Hoist motor powers the lifting mechanism, typically electrically operated. Safety features include limit switches, overload protection, and emergency stop buttons. Operators control hoist movement using buttons or levers. Loading materials or personnel onto the platform occurs at ground level. The hoist motor lifts the platform vertically along the mast. Platforms can be unloaded at desired levels, enhancing construction efficiency. Different types include single mast, twin mast, material hoist, and rack and pinion hoist. Regular maintenance and operator training are essential for safe and efficient operation.
