Abstract

An appts. is used for handling of heavy loads on a discontinuous surface. It consists of a motorised trolley which is able to ascend stairs. It comprises wheels each of which is equipped with feelers (51, 52) which when discontinuity is detected automatically prevent further rotation of the wheel. The feelers (51, 52) are the lower ends of levers (41, 42) whose upper ends (47, 48) are urged together by a spring (49). The levers (41, 42) have hub portions screw-threaded one upon the other, so that when a discontinuity is detected the resulting angular deflection causes axial movement apart of the hubs into engagement with grooved friction surfaces on the wheel and a frame member of the trolley.
