Abstract
A system for distributing the weight of a column section during lifting by a crane is provided. The system can include a roundness ring disposed about an outer circumference of the column section, the roundness ring configured to provide support to the column section such that the column section maintains a substantially cylindrical shape during movement of the column section; a plurality of shims configured to be wedged between the roundness ring and the outer circumference of the column section to improve the fit between the roundness ring and the column section; and a plurality of lifting lugs, wherein the lifting lug is configured to receive a lifting force from the crane and transfer this lifting force to the roundness ring.
