Abstract: A spring system for assisting the maneuvering of trailer ramps from a transport position into a loading position is provided. The invention is comprised of a spring mounted concentrically around a shaft about which a ramp pivots. When the ramp is in the transport position at rest on the back of the trailer, it engages and is biased against an end of the spring. The spring exerts force against the ramp thus reducing its effective weight which enables the operator to pivot the ramp into loading position with a minimum of physical effort. An arcuate tab having a plurality of holes is positioned concentrically around the pivot shaft. The holes receive a retaining pin under which an end of the spring is braced as the ramp engages the other end of the spring.
