Dumbwaiter Lift

Dumb waiters have been used for hundreds of years in homes, castles, and mansions. Dumbwaiters are small elevators (or lift) not intended to carry people or live animals, but objects. Dumbwaiters found within modern structures, including both commercial and private buildings, are often connected between two floors. When they are located in restaurants or in private homes, the lifts generally terminate in a kitchen. Until recently, most dumbwaiter systems involved a rope and pulley with a guide rail to prevent the cab from hitting the wall. In extreme cases in which the load carried was hundreds of pounds, many of people would be used to move a dumbwaiter. Modern dumbwaiters are electric but still use guide rails and need a straight shaft for transporting. The cab in the dumbwaiter should be no more than two feet wide by two feet long. Dimensions can vary for customized dumbwaiters. Electric dumb waiters operate by a series of call buttons to call and send between floors and can support more weight than a manual dumbwaiter is able. At home dumbwaiters typically hold up to 50 kg, while commercial dumbwaiters hold up to 300kg. Although the commercial size can be comparable to a residential elevator, it is still not meant for human or animal transport. However, a dumbwaiter can be configured like a residential or commercial elevator in that it can open from different sides on different floors. But, because only one opening faces outward on a certain floor, the dumbwaiter will only open from one side on a certain floor, such as the ground floor or a kitchen, and will open from another direction on another floor, such as the basement or a second floor, depending upon where the dumbwaiter shaft is designed.
