The platform lift for ships shifts cargo vertically between decks. It operates hydraulically or electrically. Unlike an elevator, it does not use a system of cables and counterweights.
Platform lifts transfer from one deck to another bulky cargoes too big for an elevator. They can be used to move cars on Ro-Ro ships.
Most platforms are hydraulically powered, though some use an electric motor.
Choice will depend on platform size and the volume and weight of the cargo to be handled. Another factor is the choice between hydraulic and electric power.
