Here's a question:
When a heavy haul company calls for a permit for a job, the permit office in our jurisdiction asks for tire sizes and axle configuration and spacing, total weight and dimensions. They then plan and give the route the carrier must use.
Do you think they ask for verification of the GVWR/GCWR on the door sticker of the Kenworth and the jeep, lowbed, and boosters?
The ratings and the legal limits are the SAME when you get into commercial trucking.
Take a typical 18-wheeler tractor trailer combination. The legal limit Federally is 80,000lbs, 12,000 on the steer axle, and 34,000 for each set of tandems. The GVWR of the truck is, no surprise 46,000lbs, which is also what it is/should be registered for.
Nope.
I spec'd 100's of heavy duty trucks. You can order components rated way over legal allowable axle loading.
Yup.
Doesn't matter what you spec out the truck with. In the case of a standard 10-wheel road tractor, its GVWR is still 46,000, and 80,000 with a tandem axle trailer. They just happen to be the same as the legal limits, unlike pickup trucks which cannot come close to hauling the legal limits.
If your hypothetical tractor unit is spec’d with a 14,600lbs steer axle GAW rating and a 52,000lbs total GAW rating on the tandem drive axles, what is the GVWR?
