GVWR?

Mooseteks point is , pop can easily pay out of pocket for scaling empty.

 

Can a 36 ft flat bridge 40 ton gvw?

 

i am not sure what the OP even wants or expects anymore?

 

Sorry, nothing can supersede what the equipment is rated for, not a registration or an overweight permit.

 

he might have typed wrong. and meant to say 48. .

 

Oscar nailed it! Manufacturer's GVWR and state registration weight are two different things. The former is the safe physical capacity the vehicle can gross. The latter is what you paid the state to legally carry for your registration. You can't register for more than it's rated unless it's a combination vehicle.

I highly doubt that Prostar is rated for 80K. Maybe with a 12K front axle and 40K tandem it would be rated at 52K. Look in the glove box at the mfr's sticker. All it will haul is the remaining weight of what is not on the trailer tandems.

 

Most OTR flatbed are rated 80,000 GVWR, this allows for approximately 48,000lbs max load on 48ft trailer.
Most trailer rates are normally rated much higher than the Truck GVWR would permit to load.
So it is unlikely you will overload the trailer rated at 60,000 minus actual trailer weight and forklift.

Figure normal max load on a 48ft trailer is 48,000lbs minus 5800lbs forklift, your load should never exceed (on paper 42,200lbs approximately) (you can have heavier load but unless they load you on a 3 piece scale that you watch closely, you likely will never get it right and legal, you will have too much weight in one area, your air gauge helps but are not 100% acurate for more weight)

Now I know nothing of 38ft trailers and maybe the 60,000lbs is more than adequate and can be ignored in this case, as in most of the 48ft trailer I have ever used.
But whichever one bust the scale is the one you need to watch, your trailer can have: trailer weight + load weight + 5,800lbs= maximum weight not to exceed 60,000lbs

As everyone mentioned your registered weight is what counts, as in 95% over the road truck-trailer combination (unless your company are doing weird thing) your registered weight is usually at your GVWR, so 80,000lbs truck loaded.
