During a turnaround at a refinery, Barnhart was tasked with removing and replacing a T-805 tower. Barnhart loaded the new T-805, which was located in the laydown yard, utilizing the LTM 1400, a 500-ton hydraulic crane. The tower was then loaded to a Goldhofer trailer with 10 lines PST.
The 500-ton crane was then relocated to the existing T-805 tower, where it was used in conjunction with a tailing crane to lift and tail the old T-805 tower.
Once the old tower was in the horizontal position it was then loaded on to a Goldhofer trailer and transported to the laydown area. The new T-805 was then transported to its final location, lifted and tailed to the vertical position and set in place.
One of the challenges of the project was to provide client specific training needed to perform work inside the refinery and to provide all necessary documentation before each critical lift. Barnhart also operated 265-ton crane service for three months to remove and reinstall E-803 exchangers and miscellaneous equipment during the turnaround.
