Steam Turbine Erection

In Mason City, Iowa, Barnhart took the next step in showcasing the multi-faceted Modular Lift Tower (MLT). On this occasion, working for a customer whose motto is "fully integrated construction," Barnhart's MLT was required not only to set the massive GE steam components, but to also "fully integrate" with a largely completed Steam Facility Building that was receiving final insulation and sheeting for operation. The problem was clear: how do you receive, handle, lift and set these 35' long, and up to 500,000 lb units with strict limits on clearances in every direction while allowing an overhead crane that was already operational to move freely for other portions of on site work? The answer was familiar.

The Barnhart Modular Lift Tower was configured to safely set the units while strategically laying out the ground preparations and pedestal tracks to "pass" through the erected building steel. In essence, the MLT was erected both on the inside and outside of the structure. Using the 60' Gantry Tracks as the primary spanning members, the MLT was able to provide a very tight loading bay between the structural walls and the concrete pedestal. The outside ends of the track were supported by MLT bents and the inside by the operating floor of the STG (Steam Turbine Generator) pedestal. Because of the almost limitless variability of the Barnhart MLT, the configuration could be precisely tailored to the existing structure.

The ability to work inside a completed structure without impeding overhead crane operations made the Barnhart MLT the ideal solution for the job. Barnhart is setting the stage for installation, maintenance, and future replacement of large power components with minimal impact on the existing structures. The versatile MLT is showing, once again, the Barnhart commitment to excellence in innovation and safety.
