I figure this would be enough to maybe carry a D11 instead of a light 349F?
Might be short an axle to scale the 375
These guys are able to transport the 375 with a lot less axles....
I've operated one of those pigs, it was H19 of a fleet of 100's of excavators. That gives some idea of the vintage and condition. The shutoff solenoid was broken so it had a parachute cord to pull to shut it off. ( facepalm )
These things last forever. I see American cranes from the 60's still at work....
