摘要

Although the hoists and roller chains used to raise and lower the 18 tainter gates at the 84-MW Tillery hydro project operated reliably for eight decades, they eventually reached the end of their useful lives. A needed tainter gate upgrade project prompted owner Progress Energy to investigate alternatives for replacing the chains to allow for reliable gate operation during this rehab. Progress Energy replaced the roller chain sprocket arrangement with disc layered wire rope drums that wind on themselves and fit the existing footprint of the tainter gate hoists. Nine gates have been retrofit to date, and ProgressEnergy is preparing to begin its tainter gate upgrade work at Tillery.
