For light, small loads handled manually — food trays, files, pharmacy items, laundry — a dumbwaiter is considerably less expensive, requires a fraction of the space and is quicker to install. It is loaded at waist height and sized for small items rather than palletised goods.
The distinction extends beyond weight. A dumbwaiter is not designed to be entered by a person and must not be specified on the assumption that it could be. Where a person needs to travel with the load, a goods lift is the correct equipment, and where operators must accompany the load routinely, a goods-cum-passenger configuration should be specified.
