Abstract: A portable ramp assembly and method of construction provides a ramp assembly with a pair of side rails and a plurality of panels adapted for releasable attachment to the side rails. The panels have an upper support surface and a like lower support surface facing opposite the upper support surface. The panels are individually removable from the side rails to interchange the upper and lower support surfaces.

Abstract: A cargo cart system with a cradle assembly includes a pair of support rails with generally sinuous upper and lower surfaces and at least one cross bar spanning the support rails. The sinuous upper and lower surfaces are maintained in mirrored relation with one another to define pairs of laterally spaced upper and lower support surfaces to support containers in a stabilized position. A method of assembling and retaining containers includes providing a plurality of the cradle assemblies; placing a first cradle assembly on the cart; placing a first row of containers upon the first cradle assembly; placing a second cradle assembly over the first row of containers; and, placing a second row of containers upon the second cradle assembly.

Abstract: A hitch device arranged for operable attachment between a pair of carts for carrying cargo provides controlled movement of the carts in train-like formation in use. The hitch device has first and second bodies, with each body having a support member having opposite ends arranged for sliding engagement with a separate pair of upright supports of separate carts when the support members are in a first position. The first and second bodies are removable from the side rails when the respective support members are moved to a second position inclined relative to the first position. The first and second bodies have a separate link arm extending generally angularly from each of their respective support members. A fastener assembly is received to couple the link arms for controlled pivotal movement relative to one another.
