Composed of a frame of 4'' channel aluminum braced with 1'' square tubing along the top. Housed inside the frame, the loading ramp is composed of 2'' angle aluminum borders and center support, with 1'' square tube aluminum support braces at each end. The 8 ft ramp can be partially or fully extended for use within seconds, and returned to its housing just as quickly. Adjacent to the ramp, the lower tray is built per the same specifications and provides support and slope to aid in loading over the truck tailgate. This lower tray may be locked into position to provide a solid base for loads requiring the entire bed and tailgate area. The lower tray provides a 21'' sloped surface providing easy and smooth continuous area for loading. The ramp, tray and frame are covered with 1/8'' sheeted aluminum to provide stable loading and carrying surfaces.
