The 8” H Guardian Rubber Dual Wedge Container Ramps with Wheel Riser Levelers create an easy ground-to-container transition for forklifts as they unload or load shipping containers with an 8” high lip. Each ramp is manufactured from molded rubber with a traction surface, and they won't shift or move during use. Sold as a pair, each ramp is comprised of one 4” H approach ramp, two 6” H container ramps, one 2” H container ramp riser pad, 4” H wheel riser leveler with two 2” H riser pads. The wheel riser leveler is designed to reduce the loading and unloading angle of your forklift. Both ramps have a lip that passes over shipping container locks so that they can be positioned anywhere along the container's edge. Dog bone connectors allow you to easily gang the ramps together if you wish to use them as a curb ramp or with a hand truck. The dual-width, modular design means that these ramps can be positioned as far or as close as needed, depending on the spread of your equipment wheels. Each ramp can support up to 20,000 pounds.
