ABSTRACT:
An attachment to the boom of a boom-type vehicle for lifting and supporting a panel assembly of the type having a panel and a purline. The purline is securely attached to the panel and disposed at an angle thereto. The attachment comprises attachment devices connectable to a forward end of the boom of the vehicle for supporting at least a portion of the purline and at least a portion of the panel. The attachment devices provide selective movement between the purline, the panel, and the boom for permitting the panel assembly to be manuvered in the desired manner at the construction site. A panel handler assembly is connectable to a forward portion of a mast assembly. The panel handler assembly includes a rearwardly disposed purline supporting portion securably connectable to the mast assembly; a forwardly disposed panel supporting portion rotatably attached to the purline supporting portion; and devices for providing selective rotation of the panel supporting portion relative to the purline supporting portion along an axis parallel to a plane supporting a forward portion of the mast assembly. The attachment provides versatile multi-directional lifting and handling capabilities which have been unachievable in prior art attachments to boom-type forklifts.
