split axle flatbed

? What? Air bags like air ride? They make the ride better instead of spring ride. Air bags doesn't magically remove all the weight.

 

No they are asking that it should split weight evenly...
Yes in theory they will,but if you have bad bushings, one axle will carry more weight than the other.
There can be other factors effecting they balance also

 

plus you can misplace the load setting and air ride will not help in that case

 

Oh ok, yeah what he said.

I had been overweight with a spread before but on my drives.

 

When I was doing the RGN they had me do a split weigh on the drop axles of the tractor and on the trailer.
With my step,.. I can only remember one time where they had me weigh one axle at a time on the trailer to get the split weight. Never really been hassled,.. RGN it was constant.

I'll chime in.

Depending on where your dunnage is located. Will depend on the distribution of the weight that rides on the two spead axles.

You can have. 17,000lbs on front spread axle and 9,000lbs on rear spead axle.

Loads don't evenly distributed between a spead axle.


In this picture the front axle of the spread is carrying more weight than the rear axle.


This box is distributed between both axles as well as weight from the white tank adding weight to the front axle.

Just a couple examples.....

 

I usually see more tire bulge on the rear axle. Go scale it and its only 250lbs more.

Then you hear someone trying to help on the CB. "Hey, your tire looks a lil low"... Then you hear the wise guy. " looks like someone didn't do a pretrip”

Ohh geeze.

 

As stated in another thread earlier I haven't been at this nearly as long as others on here but...............

If your pulling a spread axle trailer with a balanced air system (in other words all 4 bags fed by the same supply and interconnected - no regulator or ride height adjuster or anything like that on one or the other) if you see more than a couple hundred pounds difference between the axles then there's a big problem somewhere in the system/trailer.

I have loaded 50k # dead center, feet ahead of the forward axle and still been within 200-300# between the axles. Where most everybody gets out of whack scale readings is on elevated scales like EVERY Cat scale in the country. They pull forward putting the trailer on a down-hill slope and split the axles on the two forward platforms usually bottoming out either the bags or shocks on the front axle or over extending the bags on the rear axle (or both).

If you split weigh on level ground and find a big difference between the axles then it's time to head to the shop, there's something wrong somewhere and it's not the placement of the load. If you insist on split weighing a balanced system on a Cat scale drive on it backwards, split the trailer on the two small platforms and weigh it that way. The other option, stop short, weigh with the rear axle just off the rear platform but on the same level as the platform then pull ahead and weigh again, subtract the second scale ticket from the first one then compare that number to the weight of platform 3 from the first weigh and you'll have your split weight.

If spread axles were affected axle-to-axle by load placement then the coil haulers would all be overweight on the forward axle.
