Weight distribution and adding another axle question

What kind of trailer?? Got a picture of your rig?? That will give us a better idea of what you're working with.

 

The one with the issue is the quadtrac. But here are many different angles. The 4 axle trailer trail-eze photo is what i'm looking for, but will need more of a split in the axles and pullouts to make the bed 14' wide.

 

Sorry, I'm new at this

Current Situation

Current 7 Axel by bswenseth posted Apr 22, 2019 at 12:40 AM

Optional but still will not work as im only allowed 48 on rear.

8 Axle that limits rear grouping to 48K, 3 short by bswenseth posted Apr 22, 2019 at 12:40 AM

This is more of what I am looking for

Ideal 8 Axle by bswenseth posted Apr 22, 2019 at 12:40 AM

Thanks for the reply!

 

So what you're ideally looking for is an extra 500 lbs?????

And what state/S or province are you hauling in?

On the federal chart. For divisible loads. (pics you posted)
Your 4axle spread of 15 feet is ideally good for 52, not 48.
Your 4 axle spread of 17 feet is ideally good for 53,500. Not 68.
And if you had a standard 4 axle trailer (say 53 ft. flatbed for instance). 52,500 on the trailer is what they haul

That's just a national chart. Some states have their own rules thus, I asked the question.

 

Edited: I am hauling in ND, https://www.nd.gov/ndhp/sites/www/files/documents/Permits/Weight_Limitations_Chart_.pdf
At 68' I am limited to 99,500. If I add 1 more foot to the bridge and add one more axle, I can get to 105,500. adding another axle to the trailers 3 grouping will only do me good if it is 8' away from the other axles. that will give me 20,000 more capacity on the trailer axles alone.

In ND i can get an annual permit for 129,000. that would be more ideal being we have 300+ short hauls per year with this configuration. 129,000 Primary Network Permit – Annual | North Dakota State Highway Patrol

The only time that I am running too heavy is with this.

Quad by bswenseth posted Apr 22, 2019 at 12:31 AM

While Hauling this, I am 51,000 on the rear. I am unable to shift the weight forward because the detach is in the way. I am at 105,500 in this picture and the load is non-divisible.

 

What about NON divisible permits????? According to the forum, would get you 20k per axle. 60k for your group of axles.
Again, depends on ND.
Google shows NON but I'm only getting links for single trips.


OR

A trailer with a rear swing axle. I've seen trailers similar to yours where the back axle if not being used just swings up and rests on the trailer. It's also wired up with lights. So when it's being used, on the ground, there's still lights in the back of the trailer. 3 axle with a 4th swing axle. Whatever they're called.

@bswenseth

 

In ND Max weight on 3 or more axles is 48,000. Thus the need for the 4th axle to be 8’ away from the rest. We can’t take 3 X 20,000 = 60,000. I can either do 2 tandems for 34,000 max in each tandem which is 68,000, or 1 at 20,000 and a tridem axle at 48,000 for a total of 68,000.

 

And with the small yards we drive in, a Jeep (the axle added behind the trailer) will not work. Also, this would put me over the 75’ max length on a tractor/trailer.
