Question on spread axle flat beds

Look at some of the heavy haul outfits like ATS. Some of them trailers have 15 axles....

 

Hell, yeah! That's what I'm talkin' about! You gotta love it when you need oversized load signs just for the trailer.

 

Single trailers run in gary or MI, BUT in gary or IN they require a permit, the multi axle is a MI thing. The trains i posted are mine and are MI legal only, they are 2 trailers vs. one. They are good for 161k lbs with 295 tires up front. IN is only good for 134,500 on a permit so when you go into IN you have to break em up and go in one by one, leaving one at the state line then going back to get it...... Unless you are feeling lucky

 

I was always wandering about all those axles in MI, but no one could ever give me a good answer on what (weight wise) they could hauler. Thank You.

 

First off forget about the dump valve! The only time you need a dump valve is if your in a really tight turn and I mean really tight(forward or backward)! Keep in mind that if you have 40,000 on your spread and you dump the back axle thats putting all that weight on the front one. I've seen broken frames cause of guys doing that.

Just look at where your backing as your getting at your angle to start. Sometimes you can use potholes or humps that are in your way to your advantage.

 

Sorry, but I can't agree with this. The dump valve definitely helps reduce the two axles working against each other, thus causing issues with the suspension, among other things. My guess is that, if you saw broken frames, it was due to the driver running with the axle dumped for a period of time longer than it takes to make a turn. I've seen it where a driver will run down the road with the bags dumped and causes a lot of damage. I never had an issue in all the years I used a dump valve on a spread.

 

Are dump valves in the cab legal? I thought I heard somewhere they couldn"t be in the cab. I used run the Pa turnpike with a friend of mine and we would be grossing the same. He would work the dump valve and end up a class or two less than me.
