They run 100k in Canada Eh I believe.
IIRC, there is a permit in Montana for 110K or 120K
The log haulers use that a lot, a twin screw tractor a double load, each about 35 feet long. They don't load too tall with that, however. Sometimes the tractors have a self loader on them too.
When I was working down in northern NM, my boss had a fairly short run (80 miles?) down to the mill. No weigh stations and NM was notoriously lax, at least back then. He just ran a single load, but he had stake extensions and loaded
high! And that was ponderosa which is heavy compared to spruce or lodgepole.
He said those loads were running 90-100K
His trucks had 13sp R/R and 4sp Brownies - 54 forward gears
In low-low they could pull like bulldozer, which they needed pulling up out of the canyon.
That was good work and good money for all of us back then. Big trees (mostly), good scale, and private land so we didn't have to mess with the Forest Circus. I never worked over six hours a day. But I didn't want to stay there through the summer because of the heat. I was still getting checks a couple or three months after I quit, until he finally got all my logs skidded and hauled.
