Abstract

A ramp section for a load platform has one or two elongate rectangular stop plates pivotally mounted in the ramp section adjacent a rear edge of the load surface of the platform. Each stop plate is coaxially fitted with a pawl having an angularly spaced apart pair of lobes. A detent member is pivotally mounted on the ramp section rearwardly adjacent to the pawl and biased into operative alignment therewith for selectively engaging one or the other of the lobes to hold the stop plate in either a retracted position or a stop position. The detent has a foot-operable pedal portion. The stop plate is normally biased into an erect stop position so that initial depression of the pedal effects raising of the stop plate from retracted position to a latched erect position. Upon subsequent depression of the pedal, the other foot of the user is used to force the stop plate into retracted position whereupon release of the pedal effects latching of the stop plate in retracted position.
