What is the purpose?

Every component that makes up a multi axle is considered a trailer. Think of it as a pup, a 48ft rgn and then another pup...but twice the weight as a set of triple pups. So just as you would be required to have doubles and triples, the same endorsement is required for a multi axle rig.

And yes, it’s one of those jobs where you absolutely have to be able to drive.

 

33k is heavy now? You would be the lightest combo in our 200 truck fleet and we’re not a heavy haul company. Most of our trucks can’t scale over 45-46k. That’s with an open 48’ flat which we have few of.

 

Wondering what state Oregon is.

Oregon doesn't recognize federal weight limits. They have their own LOWER weight limits.

What's good federally for the NW. Is overweight for Oregon.

 

I'm 30,180 with me in it in a 2018 579 with a steel frame 48' open deck...

And the weird fuel thing they do up there.

 

Once you’re over 80k the states didn’t have to adopt the federal bridge limits. Just like some states are 97000 max with a permit (CO) and NE is 94000. Just have to know the rules where you run.

 

I don’t think all the extended weight stuff is in the atlas. It’s knowledge that you get by talking to people running different set ups in different areas. I’m ignorant of most state rules when you get east of the Mississippi River because I haven’t run out there much, most of my time has been on the western part of the country where most states allow extended weights either by permit or upping your registered weight on your cabcard. Not all states are the same so you have to research to avoid getting an overweight ticket in one state because you can’t go as heavy.

Some states the bridge measurement doesn’t really matter. Take NE for example, if you have 7 axles you can gross 94000. Spacing doesn’t matter, be it 4 on the truck with 3 on the trailer or vice versa. And 94000 is their max so trying to run 8 axles in NE is kind of pointless.

Most states do use the federal chart when it comes to extended weight. Oregon, Colorado, and Nebraska are the ones that do their own deal off the top of my head.

 

You can call the states ask them about it also. Some states only livestock and Ag products can go heavy, some states they allow everything to go heavy.

You have to figure out what you will be doing most of the time and set your truck up for that, even if it means taking a hit in other states. For example, my old company ran Idaho a lot and Oregon not as much. So our trucks were set up shorter in order to make Idaho’s off track rules with a 53ft quad. But that meant we maxed out at 102000 in Oregon. The thing is that if the trucks were stretched out in order to bridge more weight in OR then we wouldn’t have made the off track requirements for the roads we needed to run in ID. Research pays off when it comes to figuring out what you need to do.
