A dumbwaiter is a small freight elevator used to transport food, dishes, or other items between different floors of a building. Typically found in restaurants, hotels, and private homes, it helps reduce the need for staff to carry heavy loads up and down stairs. Dumbwaiters are usually operated manually or with a simple pulley system. They can be installed in walls or as standalone units, making them a convenient solution for moving items efficiently without the need for a full-sized elevator.
