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. The mast, which is the vertical assembly that does the work as a height controller for raising, lowering, and tilting the load, the mast is either hydraulically operated consisting of one or two cylinders and interlocking rails for lifting and lowering operations and for lateral stability, or it may be chain operated with a hydraulic motor providing motive power.
