A ramp for use in loading off road vehicles on pick up trucks. The ramp includes a number of ramp panels joined at lateral edges by hinges for foldably connecting the panels and longitudinal hinge means for foldably connecting support panels at or adjacent to both side edges of the ramp panels so that the support panels fold with ramp panels. In use the ramp panels are coplanar and the support panels are normal to the ramp panels to support a load on the top surface of the ramp panel.
