Replacing hydraulics system in-house
Robert Nuss and Gary Dernus, lock mechanics with the U.S. Army Corps of Engineers Pittsburgh District, give a tour and explain the work they performed to replace the hydraulics system at the C.W. Bill Young Lock & Dam on the Allegheny River. The project took a better part of a year and more than 800 work hours to complete, performed mainly by Robert Nuss and Gary Dernus. The lock and dam first went into operation in late 1934, with some piping and fittings dating back to the lock’s original construction. The mechanics’ team replaced hundreds of feet of rusted and deteriorating piping with new or refurbished material that the Corps expects to last several decades.
