A ramp assembly (20) having a frame attachable to a vehicle having a floor is disclosed. The ramp assembly further includes a platform coupled to a portion of the frame, a ramp (24) having a weight, and a reciprocating mechanism disposed between the ramp and the platform coupled to a portion of the frame. The ramp assembly (20) also includes a reciprocating mechanism disposed between the ramp (24) and the platform for reciprocating the ramp (24) between a deployed position and a stowed position in response to a load. The reciprocating mechanism (28) counterbalancing the weight of the ramp during actuation of the ramp (24) between the deployed and stowed positions to reduce the load required to reciprocate the ramp (24) between the deployed and stowed positions.

L'invention concerne un ensemble rampe (20) présentant un châssis à fixer sur un véhicule pourvu d'un sol. Cette ensemble rampe comprend également une plate-forme reliée à une partie du châssis, une rampe à contrepoids et un mécanisme alternatif installé entre la rampe et la plate-forme, reliée à une partie de cette rampe. Ce mécanisme alternatif, installé entre la rampe et la plate-forme, sert à entraîner ladite rampe dans un mouvement de va-et-vient entre une position déployée et une position repliée en réponse à une charge. En outre, ce mécanisme alternatif équilibre le poids de la rampe pendant l'actionnement de cette dernière entre les positions déployée et repliée, de manière à réduire la charge requise pour le va-et-vient de la rampe entre les positions déployée et repliée.
