The penstock sections were fabricated at the Los Angeles plant, hauled to the site on a special Needle Beam hauling unit built by Peerless Industries for American Bridge Division, with hauling performed by American Bridge personnel. The sections were set on the base of the slope using a 4100w Crawler crane and erected in place with a hydraulically powered transport frame, which was used to carry, slew, and set the penstock sections within ¼ inch of their final position along the axis.The penstock sections are fabricated in the Los Angeles Plant, hauled to the site on a special needle beam hauling unit, built by Peerless Industries for American Bridge Division.
