GCWR questions

If the trailer has a GVWR of 22,000 and a tare (empty) weight of 6,900 you can haul up to 15,100 pounds, provided that your load can be placed on the trailer in the right spot to distribute the weight evenly between the two axles and the trailer hitch. You can not overload either axle, the individual tires on each axle, or the trailer hitch. Your 30 ton trailer hitch is good for 60,000 pounds pulling and maybe 6,000 pounds of tongue weight. So, you max payload of 15,100 would have to be no more than 6,000 on the hitch with the rest divided by two axles, which should be easy to do.

 

Dump body empty, still only about 15,000 on the trailer otherwise you will overload one or more of the axles or the trailer tongue.

 

The biggest limiting factor you have is the 22,000 gross vehicle weight rating of your trailer, no matter what you pull it with your trailer can not weight more than 22,000 pounds with the load, if it weights 6,900 empty that means even with ideal weight distribution your payload on the trailer can not exceed 15,100 pounds.

 

Would 48" spread axles increase the load weight?

 

Spread axles would if the GVWR was higher, all a spread axle does is allow you up to 40,000 on a pair of axles instead of the usual 34,000. But, the limiting factor on your trailer is the 22,000 pound GVWR, no matter what the axle you can't exceed the GVWR.

 

I've got a trailer like that so... the last time I used it I moved an old D4 crawler and buckets which came to almost 14k.

with the truck you have 18300 gross that you can put on the truck. Remember that it does include the driver, fuel and what ever else you have.

with the trailer, you have 15100 gross that you can put on the trailer.

Having a spread axle won't matter in your case, the pintel will handle the weight to a point and trying to get a small trailer to move around with spear axles would be a pain - been there tried it.

 

I appreciate all the responses I still need help, I called Oklahoma Highway Patrol size & weights explained what I had & he said the trailer was legal up to 34,000 loaded on it, & said I would probably never put that much on it. I agreed that I would not have that much but my question is what is the formula for figuring this or is there a automatic calculator? Very confused at this point.

 

I think you miss typed a 40 ton tag is 80k thats more than a semi ive trying to figure max ive been coming up 16.5 17 ton in theory your only legal at 20k on single 34 tandem possible 36 on certain roads but for federal its 34k on so you need to transfer as much as needed to front or truck axle but you can possibly get trailer with axle spread and be 20 k per axle if its 65 a minus 33 for fully loaded truck that gives 32 so if you can transfer the weight of trailer onto a truck you can only hual 7.5 ton on truck so if a trailer in 10k you have 5000 if the hitch could handle mine says 6000 so that is less than trailer by 4000 so 6000 and 34000 to 40000 depending on spread of axle allowed weight subtract trailer weight 40k 46k puts you in - 10k = 30k to 36k 15 to 18 tons I was told by trailer dealer with his 40k trailer it should be 17.5 it looked like was possible it was spread axle

 

Most of this you need to look into your states laws since they are pretty much all different, just because you can run 60k dump and 40k excavator on the trailer at the same time in one state doesn’t mean you can in the neighboring one..... in fact, you might not even be able to haul the machine alone with the truck empty and a short trailer in the neighboring state
