60' load on 48' flatbed.

Correct me if I'm wrong but if you maxed out every axle on the rig couldn't you do 92K. Cause the math of 12+40+40=92 and im just going by what most people run. Now if you had heavier rears then maybe you could go more. The one thing that would hold you back would be bridge laws.

Now to the OP 60ft on a 48ft flat would not be a problem just remember your tail swing and you would defiantly have to get an over lenth permit.

 

Not jump into this but rebar is a divisible load and you could not permit for the overweight on the drive axles - yes I know that in certain states you can run /register for higher weights like OR/WA/UT minimum 105.5 k or more - but in general you are limited to 34k on the drives. In California you can run goofy overhangs as was pointed out. So there is not a single correct answer.

 

i can do 42 on the drives. but i'm not gonna get 12 on the steers. only get that when i'm empty. they get light as the rear gets loaded. but the bigger problem is the drop. it lifts the front end up. i end up with 9k on the steers when the drives are loaded to 40k.

and yep, steering sucks when i have to use the drop.

but yeah, technically that would be 91 and some change either way. but i don't think the bridge would allow that.

i don't have my atlas with me. but what's the bridge on 5 axles at 51 feet???? i don't think it's anywhere near 82k if i maxed both axles.

 

Lol, is your fifth wheel plate mounted to the very end of your frame?

 

oh yeah i understand that. I was just pointing out that you COULD permit higher then 88k.

 

That's not true. I've done it lots of times. I just pulled an old PA permit out of my file to double check. I was permitted for 20,180 and 20,180 on a 10'-1" spread.

 

i can't speak for PA. but that's the general rule of thumb.

 

right in the middle of the drives.

 

I've never heard that rule of thumb. You are allowed to permit for whatever weight the tires and/or axles are rated for. Some states use the rating written on the side of the tire, some states use tire width.

 

uh,tell that to OK and NE.
