ABSTRACT:
A roll up ramp system facilitates transition between a first elevation and a second, higher elevation. The roll up ramp system includes a securement device temporarily connecting a roll up ramp to the second, higher elevation. Further included by the roll up ramp system are a plurality of links formed by a set of parallel plates interconnected by a central support rod and a pair of lateral locking rods. Each of the locking rods is provided with a plurality of selvedge linking units having a locking portion and a pivot portion. The links are interconnected by a plurality of linking support rods, which are accommodated by each of the selvedge linking units to form a roll up ramp. A rigid, durable ramp configuration is thereby achieved. The roll up ramp system is lightweight, strong, conveniently stored in a rolled up condition and readily deployed in an unrolled, ramp-like configuration to facilitate loading and unloading of equipment from a hauling vehicle.
