Lifting apparatus and method
Abstract:
There is provided an assembly for hoisting and transporting objects having support receptacles affixed to its outer surface and for moving the objects into a desired close alignment in a predetermined location. The assembly includes a mounting bracket configured to mechanically engage with a lifting end of a crane and at least a pair of lifting plates pivotally coupled to the mounting bracket. The lifting plates have opposed non-parallel sides that are angled to engage the support receptacles during lifting of the object and during transportation of the object. When the crane moves the object to its desired location, the crane operator may pivot the assembly to facilitate aligning the object. Upon completion of alignment, the object is put down, and the lifting plates disengage from the support receptacles by sliding out of the slots of the support receptacles.
