Abstract:
1. A ramp system, comprising: a main frame for mounting to a vehicle; the main frame having an inboard end and an outboard end relative to the inboard end; a ramp assembly carried by the main frame; the ramp assembly comprising: the inboard ramp section carried by the main frame with the inboard end of the inboard ramp section adjacent the inboard end of the main frame; the outboard ramp section slidably carried by the main frame to be slidably movable between an outboardly extended position and an inboardly retracted position, relative to the main frame; the outboard ramp section being slidably movable between the outboardly extended position and the inboardly retracted position along an inclined path of constant slope; and the inboard travel surface and the outboard travel surface cooperating to form a ramp surface for travel between the inboard end of the inboard ramp section and the outboard end of the outboard ramp section; wherein the ramp assembly further comprises: an outboard extension ramp section; the outboard extension ramp section having a pivot end and a free end and being pivotally carried at its pivot end by the main frame to move slidably with the outboard ramp section and to pivot between: wherein when the outboard extension ramp section is in the deployed position, the first inclined travel path cooperates with the inboard travel surface and the outboard travel surface for travel between the inboard end of the inboard ramp section and the free end of the outboard extension ramp section; and wherein: the outboard ramp section has: when the outboard ramp section is in the inboardly retracted position, the outboard end of the inboard ramp section rests within the first depression; and when the outboard ramp section is in the outboardly extended position, the outboard end of the inboard ramp section rests within the second depression.
