Abstract: A trolley intended for a medical apparatus and comprising wheels for displacement on a floor surface. In order to push aside cables running on the floor of the working environment, the wheels are provided with a cable pusher having a pushing edge. The plate constituting the cable pusher is provided with approximately triangular cut-outs which receive stationary cams. If no external forces act on the plate, it is pressed onto the cams by springs in such a manner that the apex of the triangular cut-outs bears on the cams. The springs are proportioned so that an obstructing cable is pushed aside by the plate; however, when this plate comes into contact with a fixed obstacle, for example a threshold, the plate is pushed upwards. Damaging of the cable pusher is thus avoided and the risk of overturning of the trolley is reduced.
