A forklift truck, a lift truck or a forklift is a powered industrial truck used to lift and transport materials, normally by means of steel forks inserted under the load. Forklifts are most commonly used to move loads stored on pallets. It has since become an indispensable piece of equipment in manufacturing and warehousing operations. In a typical warehouse setting, most forklifts used have load capacities of around one to five tons, tough machines of over 50 tonnes capacity have been built and operated. An important aspect of forklift operation is that many have rear-wheel steering. While this increases maneuverability in tight cornering situations, it differs from a driver's traditional experience with other wheeled vehicles as there is no caster action, it is unnecessary to apply steering force to maintain a constant rate of turn.
