I see you found the F210, looks like she's still working as the yard goat. Is the giant Kenworth still floating around down there? That was the prime mover for several of those lowboys IIRC it had a 12V71 Detroit in it and planetary rears. My brother was a machinist at Lampson in the early 90s on the Kennewick side and he was telling me some of those trailers were built for one specific job and never used again. I remember in the mid 80s they moved some huge generator rotors to Priest Rapids dam on the Columbia river using 2 of the Transi-Lift crawler modules, it was a 5-6 mile trip at half a mile per hour.
The big KW is still there just didn't see it this trip. Truck Shop
Neat stuff. The company I retired from used one in Duluth/Superior to make one pick many years ago. It took 29 days to set it up. The picked a complete cracker assembly in a refinery and then tore the unit down and back out. It came in and out on a ship.
Good you brought that up. Lampson sends alot of cranes down the Columbia river by barge. Truck Shop
