Gross weight for a dump truck?

might be slower on takeoff is all

 

Not at all...i drive a pete with the paccar mx13 tri axle and it is rated at 500 horse. It will cruise at 75 fully loaded on interstate and has the 8ll trans

 

When you can’t get anymore on it’s maxed out that’s how we roll.

 

MN a Quad can gross 63k and a Tri is 57k

 

all depends on state and how they work laws. Federal law requires following bridge law when ever on the interstate. Some state laws will require that on state roads and some states may not. I used to live in ohio and we were required to follow bridge law. Technically we were permitted 7.5% over gross on state routes but that seems to be a gray area. But following bridge, My old 567 pete 6 axle (3 drop axles) had a light weight of about 26,550 lbs. That gave me about a 20.75 ton load limit to keep me at the legal weight of 70,500lbs for all state roads and 69,500lbs for interstate travel. Tho we always shot for the 70,500 and never bothered with the latter. Never had problems with DOT.

now recently I moved to Tennessee and they will let a quad axle truck (2 drop axles) gross 84K on state roads. That was insane to me given what Im used too but hey thats how things work. The trucks here are built heavy and made to handle that. Hell my quad axle mack has a light weight of about 31,300 lbs and yet we will still haul an average of 25 to 27 tons. We will usualy shoot for 80K lbs at most to be safe in terms of control in the hills and such. Now Tennessee also has a lot of scales around here (central ohio they were no existent), so I am often by passing scales. Troopers here seem to be pretty relaxed in terms of weight as the majority of people say they wont bother you unless you are being stupid. That said if we ever have to go out of state, these quad axles will be lucky to haul 18 tons lol.

 

As the others have said, it depends on the state. For example, Virginia follows the federal bridge law but also allow overweight permits of 5% even on the interstate such as I-95/I-495 in northern Virginia I truck around the most (The Dumfries, VA scale always give me the green light as long as I'm grossing at 81,900 or less). I-66 doesn't allow the 5% overweight permit I use, so I can only gross up to 78,000 pounds when I normally gross 81,900 otherwise. I drive a 7 axle super dump with 4 steerable lift axles. Since I haul gravel, the stone quarry I haul out of have their own scales, so we are always legal when we leave the plant since they won't let you be overweight.
