摘要： A carrier assembly for a fifth wheel mounted on a semi-trailer tractor includes a pair of generally parallel spaced rail assemblies, each comprising a bed plate, a rack of teeth superimposed over the bed plate and a rack cover plate superimposed over the rack of teeth. Bolts extend through the rack cover plate, rack of teeth and bed plate. A slider assembly includes a pair of spaced generally parallel axial elements superimposed over respective bed plates and connected by a transverse element. The slider assembly supports a tooth engaging mechanism that selectively engages the rack of teeth and is spring biased and mechanically biased toward a locked position. Rear stops are removably attached to the carrier assembly. Projections on the bed plate and rack cover plate extend into apertures in the rack of teeth to resist shear forces.
