Abstract:
A trailer, comprising:a longitudinally extending frame having rearward and forward ends;means at the forward end of said frame for connection to a prime mover;said frame including at least first and second elongated and longitudinally extending frame members having rearward and forward ends;each of said first and second frame members including a bottom flange, an upstanding web, and a top flange;each of said first and second frame members having a first section modulus of a given height which is positioned forwardly of the rearward end of the associated frame member, at least a second section modulus which is positioned forwardly of and having a height differing from said height of said first section modulus, and a transition section modulus positioned between said first section modulus and said second section modulus;at least one first running gear assembly longitudinally slidably mounted on said first frame member;at least one second running gear assembly longitudinally slidably movably mounted on said second frame member;said first and second running gear assemblies being movable from a transport position on said first section modulus to a position forwardly thereof on said second section modulus;a first movement limiting means positioned on said first section modulus of said first frame member, said first movement limiting means being positioned between said bottom flange on said first frame member and said first running gear assembly to prevent excessive movement between said first running gear assembly and said first frame member when said first running gear assembly is in its transport position;a second movement limiting means positioned on said first section modulus of said second frame member, said second movement limiting means positioned between said bottom flange on said second frame member and said second running gear assembly to prevent excessive movement between said second running gear assembly and said second frame member when said second running gear assembly is in its transport position;means for selectively slidably moving said first and second running gear assemblies with respect to said first and second frame members;and a deck supported on said frame.
