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. |
