8 axle trailers
 

I was up in Michigan last week and saw a lot of 8 axle trailers rollin' down the road. I've never seen 'em before. Are they only in the Michigan area or what?

Some states, like Michigan allow more weight without a permit if the truck and/or trailer has enough axles to carry it and spread it out. If I recall there are a couple of other states like this too, but Michigan is where it seems the most common.

They have lots of those in european countries. Once I was driving in Canada on #1, and I saw a truck hooked up to two trailers, each trailer 53 feet :shock: :?

Here's a couple shots of "dual quads" they run up here in the Northwest. 105,500 gross is a whole 'nother ballgame.

105,000 is nothin'. I've seen hay haulers grossing 138,000 pulling a pup.

This is what I was seeing:

Can't imagine how it makes turns at intersections if it's loaded heavy.

That's what I was thinking. I'm having a hard time trying to picture how a trailer with that many wheels can turn at all!

Michigan allows 150,000 gross without a permit as long as you have enough axles, part of the reason their roads all suck. Some of the axles can be lifted to aid in turning, depends on the rig.

Alot of those trucks are hauling engine blocks
