Worked in both Lift and Crane Industries since 1960 A goods lift is a lift with no floor call buttons in the the cage and can't take passengers, a passenger lift can take goods also, that is why the contract load plate in the car states both the number of Passengers and and the max load it can carry eg 8 persons or 630kg. A service lift is a small lift that can carry documents, crockery and cutlery etc between floors. A dumb waiter was a small lift that was operated by hand with via a rope. Await your comments.
