Scaling with Spread axle trailer

air ride will equal the two axels

 

I've pulled 53' stepdeck spread axle trailers, you don't really have to worry about individual axle weight as long as its not over 40,000 lbs. the trailers I pulled the axles could slide back to a tandem that's 34,000 max I never had an individual axle weight problem in about 1 1/2 years pulling them just make sure it's not over gross you should be fine.

 

If your over on an axle with a spread, chances are you'd be over gross. Best thing is to know your empty weight with full tanks then you can know the max you can haul.

 

.

If your air distribution valves are working they will equalize the axles. Think about this: If that wasn't the case you would never come close to scaling something like a big coil.

 

If one axle has 50psi to the bags, and the other 70, that will make no difference on the weight each axle is carrying. Will lifting up on the bumper make it weigh less?

The only practical way I can think of getting seperate axle weights would be to pull forward and put the front axle on the steer plate, and the rear on the drives plate and have them weight that. Also, some states do weigh the axles separately and each one cant be over 20k for a total of 40k on the trailer.

 

you have one valve. and it goes to the back. from what i've seen so far. but i haven't pulled every brand trailer.

2 years ago. one of our drivers got put out of service. becuase the axle weights didn't match. the rear bag wasn't inflated and the trailer leaned downwards.

he's not the smartest driver in the world. that's something that should have been fixed before he left. being as he loaded 10 miles from the yard.

as long as the trailer is pumped up.sitting level. your axles should be fine. majority of flatbed loads are heavy in the rear anyways. from what i've pulled so far.

your main concern would be making sure your axles are closed in the appropriate states. i have 13 on my list according to the atlas. who the sticklers are and who will make a fuss even though the atlas doesn't say anything remains to be seen. as most of my running has been west with a 48.

others on here could chime in on that note. but you can NOT run spread through all 48 states with a 53 foot trailer. 48's you can.

some trailers have air gauges too. learn to read them at 34 and 40. your truck too. learn where it sits are 34. if you have gauges.

and if you end up sitting at the shipper all day long and they wait till it's closing time to load you. be prepared to be overweight. and they don't think to highly of you when your still there in the morning becuase your too heavy. it's happend to me everytime i'm there all day.

 

It's not about making something weigh less. It's how much load is on each axle. If one has more air in it,it is taking more weight. It's a balance issue.
