Abstract
A trolley supports a person on a platform (1) and moves as a result of his changing weight distribution so that he can conveniently perform tasks above his normal reach. The platform (1) is supported on springs (2) on a frame (3) with castor wheels (4). Rods (6) are suspended from the platform at an angle, extend to the ground and are arranged so that when one side of the platform is depressed a rod engages the ground and moves the trolley in that direction. By changing his weight distribution the person on the platform causes other rods to brake or drive the trolley in other directions.
