From Cranes Today

Barnhart mobilised its 'Big Al' crane to lift two 468,000lbs miter gates at a dam on Ohio River, Kentucky. Big Al is a Liebherr LR 1700 crane mounted on a 212ft by 68ft barge. Barnhart engineers in the Memphis headquarters modified the crane to be barge-mounted. The crane, based in the Port of Mobile in Alabama, travelled via tug to Paducah, Kentucky, and then further up the Ohio River. At the site, the old gates had been removed by the Corps of Engineers, while the new gates had been delivered by deck barge. Big Al used its adjustable rigging link system to accommodate the two gates. Barnhart attached specialised turning shoes and the crane lifted the gates from horizontal to a vertical position, and rough set each gate at a 135ft radius.
