Abstract:
1. An apparatus for wheeling a vehicle with wheels onto a loading surface of a truck or trailer comprising: a ramp having a right side rail and a left side rail and a center rail disposed between the right and left side rails with a plurality of bars as treads connected to the right side rail and left side rail at locations along the length of and at the top of the right and left side rails to provide traction and cross braces connected to the right side rail and the left side rail at locations along the length of the right and left side rails, the cross braces, center rail, treads with the right and left side rails defining open spaces, the cross braces and treads and center rail blocking the wheels of the vehicle from falling through the spaces when the vehicle is wheeled across the ramp, a right hinge connected to the right side rail and a left hinge connected to the left side rail about which the ramp folds, the ramp includes a second right side rail connected to the right side hinge, and a second left side rail connected to the left side hinge and a second center rail disposed between the second right and left side rails with a plurality of bars as treads connected to the second right side rail and second left side rail at locations along the length of and at the top of the second right and second left side rails to provide traction and second cross braces connected to the second right side rail and to the second left side rail at locations along the length of the second right and second left side rails, the second cross braces, second treads, second center rail with the second right side rail and second left side rail defining open spaces, the second cross braces and second treads and second center rail blocking the wheels of the vehicle from falling through the spaces when the vehicle is wheeled across the ramp, the ramp supports a load of at least 1000 lbs., in a folded state, the right side rail and second right side rail are alongside and essentially in parallel with each other, and the left side rail and second left side rail are alongside and essentially in parallel with each other; a mounting portion having a first finger connected to the right side rail and a second finger connected to the left side rail of the ramp that mounts on top of an edge of the loading surface of the truck or trailer, the ramp has an upper center rail attached to the center braces between the mounting portion and the right and left hinge and a lower center rail attached to the center braces between the transition piece and the right and left hinges; a transition piece that is curved and pivotally attaches to the ramp and contacts ground when the mounting portion is mounted to the truck or trailer, the transition piece includes a top portion which is positioned about the tube to pivot about the tube, the transition piece includes a bottom portion which is arched and extends from the top portion to ground; and a pivot member about which the transition piece pivots, the pivot member includes a hollow tube, the second right and left side rail each have an opening through which the tube extends to attach the tube to the second right and left side rail.
