A crawler crane overturned in Oshkosh, Wisconsin yesterday while carrying out the tandem lift of a 52 ton concrete beam on a bridge project.

A construction worker, Joseph Bidler, 35, who worked for the concrete company Spancrete, died at the scene, while the crane operator, Martin A. DeRidder, 33, is seriously injured.
