A wheel support carriage member for tailers having longitudinally extending frame members, said frame members each including a bridge section for mounting a wheel carriage, said bridge section comprising a bridge beam portion generally parallel to and spaced above the main portion of said longitudinally extending frame members, means joining said bridge beam portions to the main frame beam portions comprising guide plates fixedly positioned on opposite sides of both the bridge beam portion and the corresponding main beam portions at both ends of each bridge beam portion, the area below said bridge beam portions being unobstructed, said wheel carriages including fore and aft vertically extending frame members each slidably guided between a pair of said guide plates and positioned below said bridge beam portions, hydraulic cylinder means connected to said bridge beam portions and to the lower portions of said vertically extending frame members, said hydraulic cylinder means fitting substantially within said vertically extending frame members of said wheel carriages and being actuable to force the wheel carriages and the bridge beam portions to separate, said wheel carriages each including at least one spindle member mounted thereon, a single wheel on each spindle member mounted on the wheel carriages, said single wheel being positioned to the outside of the respective associated longitudinally extending frame member, said wheel carriages including a carriage junction beam connected to the fore and aft vertically extending frame members, guide means on opposite sides of said carriage junction beam, and slidable means slidably mounted in said guide means on opposite sides of said carriage junction beam, and thus being spaced apart by the width of the carriage support beam, said spindle being fixedly attached to said slidable means below the carriage junction beam, and spring means connected between said carriage junction beam and the slidable means to spring mount said spindle member while permitting the slidable means to move in said guide means.

For use in combination with a cross beam and longitudinal frame member of a trailer, a hanger for attaching such cross beam to a longitudinal frame member of a trailer, said cross beam member having a support surface which extends past a longitudinally extending side surface of one longitudinal frame member when the cross beams are in a desired position and hook means on one end of the support surface, said hanger having a hanger frame, a pin attached to said hanger frame and extending in longitudinal direction of a longitudinal frame member with which the hanger is used and positioned to support the hook means of an associated cross beam, said hanger frame including a first portion that seats against a longitudinally extending side longitudinal frame member with which it is used, a latch plate mounted on said first portion, said latch plate having a first section extending generally parallel to the plane of an associated cross beam and adapted to extend across a surface of an associated longitudinal frame member on the opposite side of an associated longitudinal frame member from the longitudinally extending side surface which is engaged by an associated cross beam, said latch plate further including a latching leg on a side of an associated longitudinal frame member opposite from the side of the longitudinal frame member on which the first portion seats when the latch plate is pivoted to a first position, said latch plate being pivotable to a second position where it clears an associated longitudinal frame member, and removable lock means to hold the latch plate in said first position.
