Overall, Layson says the PC138 was the kingpin. “We spent 4,000 hours digging that waterhole, working shifts. The machine never stopped. We used it for everything.”
“The PC138 was the only machine on site that could move those large boulders.”
The project placed over 3,000 tons of boulders. Some of them weighed 15,000 lbs. “Occasionally we used the PC88 and PC138 together to lift them into place.”
