Reduced height combination ramp and load leveler
Abstract:
A reduced height combination ramp and load leveler includes at least two lengthwise support members, a plurality of cross members and plurality of cross treads. A retention tube is secured to each end of the at least two lengthwise support members. The at least two lengthwise support members and the plurality of cross members are preferably fabricated from an aluminum alloy having a tensile strength of at least 50,000 to reduce a height of the combination ramp and load leveler. Two stake receivers allow a single ramp to be used as a load leveler. Each stake receiver is sized to removably receive an adjustable stake. A ramp stand includes a support base and an adjustable tube receiver that is vertically positionable relative to the support base. The adjustable tube receiver retains the retention tubes.
