Abstract
A folding cargo loading/unloading ramp, particularly adapted for motor trucks, includes first and second ramp sections and an intermediate support leg assembly which is pivotally connected to the first and second ramp sections at a common hinge point. The support leg assembly includes a latch for automatically latching the support leg assembly in a working position when it is rotated from a folded position to its working position, the latch being manually actuatable to unlock the support leg assembly to rotate back to its folded or non-working position. Both ramp sections and the support leg assembly include manipulating handles to facilitate movement of the ramp between a stored position and a working position.
