<p>A materials handling system for transporting and positioning wall frames of a prefabricated building structure from a factory location to the final end position as part of a building under construction comprises three principal elements. A stillage sled (10) supports a stack of wall frames, each panel being in substantially upright orientation. The complete stack, on the stillage sled, can be lifted onto a lorry for transport by road to the building site, and can be lifted from that lorry by crane to an appropriate floor level of the building under construction. A gantry (20) at that floor level permits offloading the wall frames singly from the stillage sled. A masted lifting truck (30) receives the individual wall frames from the gantry and carries them to their precise end positions on the floor of the building under construction.</p> |
