What is an elevator?

An elevator is a platform or compartment housed in a shaft for raising and lowering people or things to different floors or levels.

What are the parts of the elevator and how does it work?

Most elevators work just like a pulley. A very strong metal rope is joined to the top of the elevator car and goes up through a “sheave” in the engine room above the elevator. The sheave is like a pulley wheel with grooves in it to hold the rope tightly.
