Truck-to-ground loading and unloading just got easier when you utilize these lightweight, rust-resistant VESTIL Mobile Aluminum Walk Ramps. Unique design features a hand crank, that when turned, manually raises or lowers ramp. Ramp rolls into position on (2) 10x3-1/2" pneumatic wheels that must be raised when ramp is in place for maximum capacity. Safety chains connect ramp securely. Heavy-duty features include: 100% welded aluminum construction, underside deck ribs for strength, and overlapped, tapered ramp end for easy access and a smooth transition. 2"H curbs prevent run-off while the non-slip serrated deck adds safety. Made in USA.
