Abstract

A lightweight, portable, cargo-retaining header wall is provided which serves to vertically, transversely, and securely span the interior space between opposed walls of a polygonal cargo-receiving container such as a truck trailer or railroad boxcar to prevent cargo shifting beyond the header wall. The header wall preferably includes: a bottom rollered lattice structure composed of a plurality of interconnected bars spaced just closely enough to prevent cargo movement therethrough; a jacking member; and a driving assembly mounted to the lattice structure and receiving the jacking member for incrementally moving the jacking member, the assembly having an operating lever. To use the header wall, a person rolls or lifts it into a transverse, vertical, interior position between two parallel container walls and then moves the lever back and forth to advance the outboard end of the jacking member into tight-fitting engagement with the adjacent container wall; continued operation of the lever causes the opposed side of the lattice structure to also tightly engage its adjacent container wall to thereby secure the header wall between two opposed container walls.
