Abstract:
1. A device for lifting oversized pieces of material, the device comprised of: a spreader bar capable of attaching to a hoisting system of a lifting vehicle; at least two cross members attached to the spreader bar; at least one cross-member power source attached to the spreader bar, the at least one cross-member power source connected to at least one drive mechanism; the at least one drive mechanism connected to at least one of the at least two cross members; a load-pick power source attached to each of the at least two cross members, the load-pick power source connected to at least one load-pick drive mechanism, the at least one load-pick drive mechanism connected to at least two load pick latching mechanisms which power two load pick points wherein the at least two load pick latching mechanisms are positioned by the load-pick drive mechanism along a length of the cross member so as to vary a distance between the load pick points, thereby allowing the load pick points to engage with a lifting connection on an object to be lifted; and the cross-member power source and the load-pick power source each electrically connected to an operating panel in a cab of the lifting vehicle.
