ABSTRACT:
Several elongated tread plates are pivotally connected together to form the central load-bearing portion of a ramp. Rigid side rails can be latched to the assembly of tread plates to maintain the tread plates with their upper surfaces coplanar. The side rails can be unlatched from the tread plate assembly, whereupon the tread plate assembly can be rolled to compact condition for storage.
