ABSTRACT:
An approach ramp for an automotive support platform includes first and second ramp members, the trailing end of the first ramp member being pivotally connected to the leading end of the platform. The second ramp member is both slidably and pivotally movable with respect to the first ramp member. Each ramp member carriers rollers at its leading end for engagement with the floor when the platform is lowered to an access position. In one configuration the ramp members are disposed in overlapping parallel relationship to define a single ramp incline. In a second configuration the second ramp member is extended from the first and is inclined with respect thereto to form a dual-slope ramp incline.
