ABSTRACT:
A system for aligning a crane upper works with a crane lower works for redecking the upper works with the lower works comprises at least one roller operatively connected to at least one of the upper works and the lower works, and at least one surface operatively connected to at least one of the upper works and the lower works. The at least one roller is engagable with the at least one surface such that the roller moves along the surface under the influence of gravity for aligning the upper works with the lower works. A method for aligning a crane upper works with a crane lower works for redecking the upper works with the lower works is also provided. The method comprises the steps of: providing an upper works having a roller operatively associated therewith; providing a lower works having an alignment surface operatively associated therewith; positioning the upper works with respect to the lower works such that the roller engages the alignment surface; and moving the roller along the alignment surface under the influence of gravity to align the upper works with the lower works.
