A lifting spreader for an irregular object such as a helicopter. In order to adapt a standard container frame to lift an irregular object, a pair of spreader bars containing slings is provided. Each bar has a central pipe welded to a container box at each end. An L-shaped padeye having a hole in an outer corner is welded to each box and an end stand is welded transversely to the padeye for stability. An extra thickness of material is mounted on either side of the padeye around the hole to provide extra strength where the sling and shackle arrangement is hooked to the spreader bar.
