Dumbwaiter Elevator

Elevator, also called lift, car that moves in a vertical shaft to carry passengers or freight between the levels of a multistory building. Most modern elevators are propelled by electric motors, with the aid of a counterweight, through a system of cables and sheaves (pulleys).A dumbwaiter is a small freight elevator or lift intended to carry food. Dumbwaiters found within modern structures, including both commercial, public and private buildings, are often connected between multiple floors.Arguably, the most significant difference between dumbwaiters and elevators is that they serve completely different functions. Elevators primarily carry passengers while dumbwaiters solely carry items between floors while unattended.
