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.

A lift platform comprising: a platform having a pair of elongate stop members, each of said stop members being mounted on said platform for movement between a retracted position and a stop position wherein said stop member confronts a load-bearing surface of said platform, each of stop members being movable between said two positions independently of the other of said stop members; and a pair of latch means, each comprising cooperating parts of one of said stop members and said platform, for independently latching each of said stop members against movement from said stop position toward said retracted position or alternately independently latching each of said stop members against movement from said retracted position toward said stop position, one of said cooperating parts being movable out of latching contact with the other of said cooperating parts for releasing said member for movement between said retracted position and said stop position.
