Dumbwaiters are small freight elevators (or lifts) intended to carry objects rather than people. Dumbwaiters found within modern structures, including both commercial, public and private buildings, are often connected between multiple floors. When installed in restaurants, schools, kindergartens, hospitals, retirement homes or in private homes, the lifts generally terminate in a kitchen. They have a carrying capacity of upto 450kgs. Such lifts can be installed using both traction and hydraulic lifts depending upon the application and number of floors.
