Since the driver's seat with an operator located thereon can be moved vertically on the mast together with the load-bearing device, such material handling equipment is also referred to as man-up vehicles or man-up industrial trucks. In various types of man-up trucks, the mast is telescopically extendable and retractable, the driver's seat is fixed in height adjustable at the highest extendable telescopic stage of the mast.
