3 & 4 axle weight limits

What are you permitted at? This is really a company specific question, but I thought WA still had a 105k gross limit without permits?

 

Get out your bridge law book, tape measure, notebook paper, and calculator. That will give you your axle, inner bridge, and outter bridge limits. Also was the lift on the truck or trailer. If on the trailer was it in front of or behind the fixed axles. Hauling heavy is an all new animal compared to the 5 axle light weight guys.

 

generally speaking triples are good for 42k and quads are good for 48k.

Then WA will likely restrict you to 105,500 Gross.

Dropping the pusher axle adds weight to your drives because it takes weight from your steers. You'll notice your steers are often very light in the range of 10-11k with the pusher down unless you have a custom extended slider and RGN extended neck that lets you slide the fifth wheel waaaaaay up.

 

I hope "someone" didn't mean to dump it only to go through scales, you get caught doing that it's definitely frowned on by the boys with the ticket books.

If you can't get the plate over the front drive, the lift is worthless- most NW spec trucks have the long slider. I think the "average" tractor here: 12k steers, 11k lift (w/255's), & 34k drives for legal weight. The trailer depends on the configuration/spacing- single(lift)+dual+dual+single(lift); dual+dual+dual+single(lift); dual+dual+dual.....

My lift (9'4" spread) is around 60/40 with the plate just forward of the front drive.

 

I had the same spread on my lift and i was always told 42 or 42 500. I run out here towards SD and NE though

 

I just re-read my post, even I'm scratching my head..... "huh?". I was thinking it, it just didn't make it to the keyboard.
I should have said:
"My lift (9'4" spread) is around 60% off the drives & 40% off the steers with the plate just forward of the front drive."
