What are the basic components of a building hoist?

The basic components of a building hoist include the hoist machine, mast or tower, guide rails, lifting cage, counterweight system, safety devices, electrical control system, and communication system. The hoist machine powers the lifting and lowering of the cage, while the mast provides structural support. Guide rails ensure the cage moves vertically, and the counterweight balances the cage's weight. Safety devices protect against accidents, and the electrical control system manages operations. The communication system allows for coordination between the hoist operator and other construction personnel.
