 Topic: May have some Issues brewing
Posted: Yesterday at 5:58pm |
On truck I daily run. Is a Heavy monster at 35,000 Empty, then is a Bigger issue, sat down with tape measure, and did the Old Basis Bridge Formula that seemingly NO ONE ever bothers with anymore. Used to hand build Dump Pup Trailers for behind Tandem Dump trucks and had to alter several that could not meet Bridge Law. Current truck and trailer measure out well above 52' long, HOWEVER, under Bridge Rues must measure from Front driver to rearmost trailer, can ONLY achieve 34 feet there, shuts off the Max GVW to 64500 against license weight of 80,000, close to 8 ton I generally carry as TOO Much.
MoDOT has begun to stretch the tapes recently.

34 feet from the axle of the forward driver, to the axle of rearmost of the trailer?
Are you allowed to have a tag axle in front of the drives?

I tried to follow the science, but it was not there. I then followed the money, and that’s where I found the science.

Truck has not the WB to do that, what most do is add weight dispersal axles on the trailer frame to reduce axle to axle weights and reduce the signature as required by the Bridge Formula, which BTW is out of date to the 1950s.
This trailer is considered a Quarter Frame, was intended for use in building demolition inside cities where a Commercial Zone standard eliminated the Formula as to roads destructions. In STL KC or Columbia MO can exceed axle weights by either adding axles or buying a permit, on the Interstate system is not allowed.

Add 12,000 for your steer axle. That will get you to 76,500, so just short of 80,000.

Incorrect, Bridge Formula once get to the Drives and Trailer four axles that is ALL allowed. Bridged Weight.
Actually took a class on this nearly as confusing as it looks BS Formula, State Brown shirts noted the Drop in GVW once lose trailer length, we all tried to add the steer but the number is Total GVW reduced due to short length.

When I was pulling tank trailers and the 80,000 GVW - couple tickets for overweight .
Found the front axle was light by what tickets were for . Never over the 80 but off on the bridge weight .
Finally brought scale weight to shop foreman to have him move trailer pin to put weight on front axle - moaned about that would put some other trucks to heavy if they pulled the same trailer . It seems their answer was pay the fines , not do the work .
90% of the time I pulled the same trailer over 3 years with same power unit day cab, and they were worried some owner operator with a sleeper might use the trailer .

One of the gravel pits I pulled out when I hauled rock , had a IH dump truck in shop most of the time , Asked about it - said it was so heavy it could not hold but 1/2 load their other trucks carried - so they used it as a PARADE TRUCK - cleaned and polished but not worked .
