Dumbwaiter elevators are food service elevators used mostly in multi-storey restaurants, villa-type residences, dormitories and dining halls where service products such as plates and trays are transported. Car dimensions are much smaller than the cars of other elevator types in parallel with the intended use. Automatic guillotine type doors are generally used for such elevators. Due to the characteristics of the materials carried inside, the cars are made of materials suitable for hygienic sensitivities.
