    I'm getting some good stuff here, just what I need. The more replies I get, the more I see I don't/didn't know.
    I'd think on your tire inspection, you'd want to look for rocks and even logs stuck between the duals as well.
    Very good pointe on that hog wood, sure don't need to screw myself up worse than I already am.:biggrin_2559:
    Ya know, there's something that always scared the crap out of me down south. It was the way those guys hauling the pole logs did it. I actually saw many times, they'd use a rope, instead of chains and boomers to tie those logs on. And I saw a number of them with only one chain, plus the way they were loaded. It didn't look safe to me at all.
    The way we haul the logs around here, mostly pulpwood, they are cut 100" long and hauled sideways on flatbeds. I can see very easily how top heavy those must be. That's something to be taken to heart for sure, I've seen where a rookie rolled a few times, and no way do I want that. Geez, scares the crap outa me just thinking about it.
    I've always been very careful with following distance and speed around corners, ramps, etc., but I've never had a load as top heavy as these will be, so trust me, I'm really going to be extra cautious until I get a better feel for it, and I assume no two loads will be alike.
    Here in Michigan, we can run 160k gross, if you've got the axles. When you go to scale, I can't see how you could possibly get a weight like you do with a tandem or spread. How do you figure what you have per axle? With these axle setups, I think each axle on the trailer should 17k or less. I know to multiply the number of axles by 17k on the trailer, add 34k for the drives, and approx. 12.5-13k on the steers, [Depends on axle and tire rating on the steers], to get the gross. :biggrin_25525:

    When your gross exceeds 80,000 in Michigan your drives automatically drop to 32,000. Your trailer axles will only get 13,000 per axle unless there is a minimum of 9' between the axles then the single axle(s) get 18,000 per.

    I doubt there's any steerable axles on these trailers, there will be just straight lift axles.

    Oh, OK, I must have misunderstood what I read, thanks. Your steers stay the same?:biggrin_25525:

    Ya, your good for 36k with a 9', I though I remembered that. I forgot to mention, I drove a 53' rolltop spread a few times.

    I hear ya about the log loads down here. Up home in Maritime Canada they wouldn't be allowed out of the yard.:biggrin_2559:
    Re axle weights, talk to your loader. They're usually pretty smart about proper loading. Also the other drivers. You might have an air guage in the tractor and trailer; so much pressure equals so many pounds.

    Glad to hear you're taking safety seriously. You'll do fine and you'll learn the rest of the stuff as you go. Roll on driver.:biggrin_25525:

    Safety is the #1 thing, no short changing there, in the past and now as well. :biggrin_25519:

    They don't "steer", as in activated by a wheel, but they're allowed to move and follow curves as the trailer moves, turning with the trailer (and truck). That's why you can't back up with them down... as you cut the wheel, turning and backing, they'd try to follow, and you'd be all screwed up, axles going every which way, and can tear out of thgeir mounts - I've seen it, luckily haven't done it.
