Claim:
In combination, a truck flatbed and apparatus on said flatbed for preventing shifting of a load on said flatbed during offloading, comprising: dunnage timbers spaced along a length of said flatbed, said flatbed having side edges, said timbers extending at right angles to the longitudinal axis of said flatbed and toward said side edges of said flatbed; said load resting on said dunnage timbers; pairs of chuck and lock units spaced along a length of said flatbed, each pair having one lock unit adjacent each side edge of said flatbed; each chuck and lock unit comprising being L-shaped and having one leg on said flatbed extending horizontally at right angle to the longitudinal axis of said flat bed and a second, upwardly extending leg at a distal end of said horizontal leg adjacent said side edge of said flatbed; said upwardly extending leg having a vertically extending socket portion; said chuck and lock units resting on and being unattached to said flatbed, thereby being readily repositionable from one flatbed to another; each said horizontally extending leg having a pair of spaced side extensions for receiving an end of one or more dunnage timbers; each said socket portion of said upwardly extending legs receiving a bottom end of a vertically extending savior extending the full height of said load; said load comprising members stacked on said dunnage timbers between said saviors at opposite ends of said dunnage timbers; a strap for each pair of chuck and lock units extending from one side edge of said flatbed over top ends of each pair of saviors to an opposite side edge of said flatbed for securing said load between saviors, said straps being releasably attached to side edges of said flatbed; and whereby said saviors hold said load members in place during offloading after removal of all straps at a destination; and means for adjusting the height of each upwardly extending leg for the height of the load.
