ABSTRACT:
A system and method for aligning the upper works assembly to the lower works assembly of a crane to facilitate redecking of the assemblies. The system and method involves suspending, preferably by pendants, the lower works from the upper works in such a manner that the influence of gravity will automatically level and align the lower works with the upper works. Alignment and redecking are accomplished without transferring the weight of the upper works assembly to lower works assembly.
