Dumb-waiter elevator

---

A dumbwaiter elevator is a small, freight-only vertical transportation system used primarily for transporting goods or small items between different levels of a building. Unlike passenger elevators, dumbwaiters are not intended for transporting people and are typically smaller in size. Dumbwaiter elevators are commonly used in residential homes, restaurants, hotels, hospitals, and other commercial or institutional settings where there is a need to transport small items or supplies between different levels. The dumbwaiter cab is a small, enclosed compartment designed to carry goods or items between floors.
