ABSTRACT:
A foldable ramp having an improved hinge construction to increase load capacity. The foldable ramp overcomes the disadvantages of the prior art by providing a ramp having a first ramp section and a second ramp section, pivotable relative to each other between a folded storage position and an open working position wherein the ramp sections are prevented from pivoting to a coplanar position relative to each other in the working position so as to increase load capacity.
