Barnhart Crane & Rigging Beats the Clock For Timely Delivery of Transformer
Mar 17, 2003
(MEMPHIS, Tenn.) Barnhart Crane & Rigging successfully transported a 225 MVA transformer from Tennessee to a Central Alabama generating station in six days, easily beating the average two to three week period typical of such moves.
At the request of its client, Barnhart effectively expedited the delivery schedule for a 291,735-lb. transformer and additional accessories, despite delays caused by snow.
According to the cleint spokesman, the need for the faster-than-normal delivery was driven by the construction schedule. "We had to replace a damaged transformer at the Central Alabama station, and we needed the replacement in a hurry to keep on schedule. The transformer from Tennessee was almost a retro-fit, with just a few minor changes."
After pushing for and receiving a speedy rail clearance from CSX, Barnhart removed the massive transformer from the same spot it had set it a year previous. Barnhart's second encounter with the transformer, which was being moved to the Alabama facility, involved the use of a hydraulic jack and slide system to move the transformer onto a trailer for over-the-road transportation. Specially designed to lower the height of large equipment, this trailer used deck spaces to meet the height requirements of the transportation route.
At the rail siding, Barnhart crews used the trailer to elevate the transformer and then moved it on slide beams onto the heavy duty rail car. The rail car had to be expedited using a dedicated locomotive from North Carolina to Tennessee and then to Alabama. The eight-axle depressed center car was transported along the 400-mile route, with Barnhart safety managers providing oversight during the move.
At the Central Alabama rail spur, the transformer was hydraulically raised again, utilizing Barnhart's gantry system. It was then placed onto a hydraulic platform trailer for the 13-mile transfer to the construction site. The timely delivery of the transformer facilitated the testing of the new plant on schedule. Stockman said that construction, which began in June 2001, is on schedule and is now in the final construction phase. The 885-megawatt combined cycle, natural gas-fueled facility should come on line in late spring or early summer of 2003.
