Abstract

An improved fold out ramp system apparatus for a flat bed trailer includes a tapered tail end extending rearwardly from the trailer; at least one transition ramp having a front end pivotally secured to the trailer in close proximity to the juncture between the tapered tail end and the trailer; a clamping mechanism for selectively clamping the transition ramp in either an elevated configuration or a sloping configuration; and a tail ramp pivotally secured to a rear end of each of the transition ramps in end-to-end relationship. A brace pivotally connected to the tapered tail end is releasably connectable to the tail ramp to form a blocking configuration. A leaf spring having one end fixedly secured to the trailer is adapted to urge the transition ramp rear end upwardly to counter the weight thereof. Similarly, a torsional spring is adapted to urge the tail ramp free end upwardly relative to the transition ramp in order to counter the weight of the tail ramp. In a second embodiment of the invention, a coil spring replaces the leaf spring to urge the transition ramp upwardly to counter the weight thereof, and a pair of rotatable rods with handles are provided to lock the transition ramp in the elevated position and to lock the tail ramp in a travel position.
