Single axle frieghtliner GVWR

GWVR= Gross vehicle weight rating. That is determined by the manufacturer of the vehicle ( truck or trailer) since you state it is a single axle. I will assume you mean single drive axle you will need to look at your axle ratings and you should get pretty close. It wont be 65,000lbs or 80,000lbs for sure.

GCVWR= Gross combination vehicle weight rating. That will include truck and trailer.

Also look in your door jamb on the driver side. There should be a tag or sticker with all that info including you vin number.

 

It all depends on what your axle and tires are rated for...

For example: if you pull a tandem trailer thats 34K, if your steer axle is 12K and your single axle could be 17K-20K....... 34+17+12=63k

Check when you open your door there should be a sticker with your vin# and possibly your GVWR

Hope this helps

 

I guess viking beat me to it ^^

 

Are you sure that's not GCWR? It all depends on your setup. Just because it says 80K don't automatically think 12K/34k/34K. You might have a tri axle or spread axle trailer raising your trailer tandem weight.

What you need to determine is what weight you can put on your drives.

What is the single axle rated for? They make several different kinds. Look at the tag on the axle itself if it's not listed individually in the door. It'll have the axle rating on it.

Then look at your drive tire's max weight rating. Multiply by 4 and that is them group of tires max unless it has super singles, then by 2.

Use the lessor of the two, axle or tires?

Then you have to consider state and federal law after that. All allow between 18,000 and 22,400 lbs on a single axle.

Let's say you have a 20K axle and 22.5K tires on your drive. 20K is your limit on your drive except for IL which is 18K on state roads.

Once you figure it out you'll know your limits. It should be around 65K-66K is what your max will be hauling a regular 53 footer. But stick the right trailer behind you then you could reach the 80K limit.

Go to the Cat Scales and get your empty weight. Subtract it from the weight rating you just calculated and you'll have a good idea what you can haul.

Also you have to consider how you load that trailer. You just can't double row pallets the whole way if you have a heavy load. You might have 3-4 singles before a double row pallet to push the weight towards the back.
Companies that use single axles usually haul light stuff.

 

IF! you put 2 trailers with a total of 5 axles=40t just like a semi.
3 trailers=105,500lbs. depending on the state regs.

 

Even if that single axle was able to haul 80,000 GVW that does not mean that you can legally haul a load Grossing 80,000 LB U Can't Axle Proper. U will need a Tag axle to haul that much.

 

if pulling doubles should be able to gross 80k

 

12 steer
20 drives
34 trailer=66k.(45ft. trailer)

12 steer
20 drives
20 trailer=52k.(28ft. trailer)

Depending on a few specs. like bridge laws,tire ratings,ect. I don't know how much simpler you can make it.
