If you need to haul big, you need more wheels. That is certainly the motto of Atlantic Tiltload Ltd, when they had a Terex Finlay J-1175 Tracked Jaw Crusher to transport.
The Western Star, fleet number 78, had a spare axle not in use, but the Trail King trailer rig had all its wheels on the ground, including a three axle jeep and two axle booster. According to the Finlay web site, the operating weight of a J-1175 rock crusher is 113,096 lbs / 51,300 kg. I expect shipping weight might be a little bit less.
