ABSTRACT:
A mobile inclined ramp having longitudinal members that are disposed at the sides and are connected by transverse members that have a U-shaped cross-sectional configuraiton, with the cross parts of the transverse members being directed downwardly. To increase the load-carrying capacity of the tranverse members and to increase the traction of the travel surface of the ramp, plates are disposed between the cross parts of the transverse members. At the top, these plates end approximately at the level of anti-slip or traction elements of flanges of the transverse members. The plates are securely clamped between adjacent transverse members by bolt connections.
