I've been doing some checking. 100k annual os/ow permit here is $100 annually. I will have to have one since this crane is 8ft 8 in. 8 ft 6 in is out max here without permit. 88k lbs gvw is our limit here on state roads. With the permit, I'm allowed 22k per axle.I've had one for 10 years. When you really need a RT, a truck crane isn't getting there. It sat at a school project for 6 months, 2-3 days a week usage last year. Real busy for 2-3 months of it, less at the start and finish.
That project was a flat clay mudhole that wasn't walkable after a rain. We never would have gotten it done without the RT.
I have no idea what your state rules are for oversize/ overweight. If they will let you have 20k on a tandem you should get it on a tandem. 57,000 for crane and 20,000 for truck and 15-18,000 for trailer is 92,000 gross. Max, no permit, is 80,000. Rear axles of the trailer and your drives will be the problem.
For me in rental, the biggest pain with the RT is the hauling. There's never room to drop/ unload, its hard with narrow roads and tight corners. So we only take the RT if its the only thing that will do it. Which means I just didn't want a terrible lot of money tied up in one, but I still like having one. We have roaded ours about 3 miles at the most. I know some guys road them much further, but you want to watch transmission temps.
Ask a local dirt guy/ equipment hauler. He'll know what he needs for a 60,000lbs excavator.
Unfortunately, it basically looks to close to call. Have to load it and go to my local cat scale. It's close enough trailer tare weight is going to be a factor. The safe bet is a triple axle. Just more weight and tires to drag around. My semi has a 370 hp C10 10 speed so its gonna be pushing it already with a tandem. I'd rather stay away from a triple for maneuvering where we need to go.
