Dumbwaiters Elevators - types of elevators / lifts



                      They are small freight elevators intended to carry objects rather than people , Whenever groceries or laundry need to be sent up and down the stairs without making unnecessary trips that can quickly tire people , people can simply place what needs to be transported in the dumbwaiter and press the button to send it up or down stairs. Dumbwaiters are most often built into or adjacent to a wall. 

A simple dumbwaiter is a movable frame in a shaft, dropped by a rope on a pulley, guided by rails; most dumbwaiters have a shaft, car, and capacity smaller than those of passenger elevators, usually 100 to 1000 lbs
