    Default 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.
    Finding the right trucking company is like finding the right person to marry. I really comes down to finding one whose BS you can put up with and who can put up wih yours.

    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.

    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.

    Michigan allows up to 164,000lb GVW- with the right number and spacing and design of axles/tires.

    Most of those lift axles are steerable and will track right through the turns with little or no scrub or fuss.

    Some vandal would have a blast flattening all of those tires.

    164,000 is just a suggestion. I haven't seen one yet come into a mill under 170,000 hauling pulpwood. Heaviest I ever saw was 193,500.
    Don't trust anybody. Especially that guy in the mirror.

    On a 8 axle trailer, 5 axles will usually lift. For running empty. And the older trailers didn't have steerable axles, so you had to lift all 5 axles to turn corners!

    We don't have any 8 axle trailers here in ontario, but we do have alot of 5,6, and 7 axle trailers tho.
    Also have alot of super b trains
    3 axles on the lead trailer, 2 axles on the pup.

    Some super B's also have a lift axle on both the lead and pup, making 7 axles total on the trailer.

    Ontario does not allow double 53 ft turnpike trains, but quebec does and alberta does too i think. I have also seen turnpike doubles on NY thruway.

    Ontarios max gross is 63 500 kg ( almost 140 000 lbs) without a permit.
    usually a 5 or 6 axle trailer and tandem tractor

    A regular tandem trailer and truck is legal for almost 86 000 lbs here in ontario too.
    12k on steer, 37k on drives, 37k on trailer

    Also we can run 20 000 lbs front axles and tires if we need to get front axle weights legal. All dumptrucks have 20 000 lb steers
