"This 30,000 lb. portable aluminum yard ramp system is the perfect solution for creating a portable loading dock for access to trucks and trailers. The 101” extra wide modular ramp system can easily be set up by two people in less than 15 minutes without any tools. The 6"" high rail guards are integrated into the ramp for added safety and maximum structural support. The modular design consists of eight ramps and three adjustable height support stands. The upper ramps feature a plate end for a smooth ramp to truck transition, the center ramps have pin ends that secure to the stands, and the lower ramps terminate in a knife foot for a smooth ground to ramp transition. The ramp system can be used in different configurations from 8' to 30' L, and will accommodate docks, trailers or trucks from 15"" to 60"" H. The entire system will fit in a pickup truck bed or a 4 x 8 trailer, and ships economically on one pallet via common carrier. US Patent #10710824."
