V.C. Summer Nuclear Reactor Heavy Lift


To construct the Summer Nuclear Generation Station for South Carolina Electric & Gas, Bigge Power Construction allied with Timberland to build the largest-ever ringer derrick of its type. Timberland provided complete hoist and control systems for each of Bigge’s two 6800 tonne derricks. Each system included four 75-ton traction winches with reel winders and four high-capacity diesel powered hydraulic power units with a synchronized PLC control system.


To lift and place the new station’s main module, all 8 hoists required precise synchronization through Timberland’s proprietary PLC program.


The placement was executed efficiently in 2013. The Timberland system was able to ensure safe, evenly distributed loading of the boom structure throughout the lifts.
