DUMBWAITERS

A dumbwaiter is a semiautomatic electro-mechanical hoist operating in a structural trunk. The car of a dumbwaiter is arranged to carry ship’s stores of varying weights and package sizes. Figure 8-10 illustrates the parts and controlling mechanisms of a dumbwaiter.

You should inspect the dumbwaiter car and hoist every 3 months. Check the condition of the load cable (it could be a chain or wire rope cable), motor brake, friction clutches, overtravel limit devices, door interlock control switches, and safety devices. You must follow the manufacturer’s manual or the procedures specified by the PMS when making repairs. You are required to complete a PQS for this equipment. For more general information, read NSTM, Chapter 572, “Shipboard Stores and Provision Handling.”
