Device to permit trouble-free movement onto and over a ramp

摘要

The invention relates to a device to permit movement onto and over a ramp which is mounted on passenger vehicles, such as buses or trams. The said ramp is accommodated in a flat casing which is pivotably articulated, on its side opposite the extension side, in the lower floor region of the vehicle. The extension side of the casing is resiliently supported and the pivot region of the casing is limited with a stop. A limit switch which can be actuated during pivoting of the casing acts, by means of its control signal, on the control circuit provided for retraction and extension of the ramp.
