Over Head: The distance measured from the upper landing floor to the top of the elevator hoistway
Travel: This is the distance measured from the bottom landing to the top landing.
Rails: These are the metal tracks that guide the elevator up the hoistway. Look for elevators using solid steel T-rails, as these will give the smoothest ride.

Sling: The heavy Duty metal support frame that carries the elevator car.
Car: The finished portion of the elevator that people ride in.
Car Gate: Door or gate that is attached to the elevator car and travels with the car.
Hoistway Door: Door that guards the opening in the hoistway at each landing.
Electromechanical interlock: Electrically wired lock attached to the hoistway door that prevents the door from opening when the elevator is not stopped at the landing. The elevator will not move unless all doors are closed and locked.
