These lightweight, yet durable aluminum ramps are built to load heavy machinery such as skid steers, tractors, trenchers, or other machinery with pneumatic wheels or rubber tracks up to 10,000 lbs. A reinforced stub foot makes it possible to load from a range of 36" to 42". The 2-beam ramps also feature extra wide, serrated rungs that provide maximum traction in the snow, rain, or heavy mud. The ramp is attached to the trailer using a long pin and skid seats (sold separately) that are welded to the back ends of the trailer. Wall brackets are also available to allow users to drive loading equipment into basements.
