Bowl Mill Remove and Replace - Arizona

Barnhart was contracted to remove and replace a bowl mill at a power plant in Arizona. The piece weighed 40,000 lbs. with a 12' X 12' circumference. Overhead and surrounding building structural beams made access a challenge.

Previous removal methods had been complex bull rigging combined with a dual crane pick. Barnhart's solution was to utilize its Twin Lift, a time-saving solution, and put it close to its maximum in boom, radius and weight tolerances.

The job required navigating the lift through structural beam obstructions and traveling with the bowl mill to an onsite location where it was set on stands. The bowl mill was replaced once repairs of the lower unit were complete.
