  1. Fire truck suspension

    We own a warehouse and rented a section out to a guy that repairs fire trucks. Looking at the tandem fire trucks that come in and out, they all are running either Hendrickson air ride or some other walking beam/air hybrid. I’m wondering why this is? I would have thought they would just have standard air ride, unless things like pumpers go off-road more than I figured.
  2. 230,000 LB load

    Yes, the load is actually suspended on cables.
  3. 230,000 LB load

    This autoclave had been shut down for a few years. But yes, the plant is nowhere near what it was. At the height of WWII, about 6,000 people worked there. Until recent years, there were about 3,000. Now I think they are less than 500.
  4. 230,000 LB load

    The load is a autoclave. Used to cure composite airplane wings and components. It's basically just a big pressure cooker.
  5. 230,000 LB load

    More pics.
  6. 230,000 LB load

    Here is a load we helped with back in the spring. Going from Nashville, TN to somewhere in Mexico. Perkins was just taking it to Laredo, TX where they transloaded it to a Mexican outfit. 230,000 LB, 16' wide, 90' long, and 15' tall. I
  7. 12 speed PTO

    Does the rear mount PTO change speed with what gear you are in like the side mount?
  8. That sounds like it. I did notice a roof mount A/C. Is it just a B body on a late model running gear?
  9. A week or so back, I saw a old B model pulling a tanker through TN. It was white, I didn't get the name on the door but I think the state said Connecticut. It had a sleeper and a fairly long frame behind the sleeper. I'm fairly sure it was air ride. Anybody know who it was or seen the truck before?
  10. 12 speed PTO

    Isn't that the PTO used to run a winch and whatnot and use max engine HP though it?
  11. Frame Repair

    No, you are never supposed to weld horizontal on a frame. That's why I don't like the step cut. Another reason I don't like the step cut is the angle changes, that can lead to cracks developing. I will probably be ok, but like with all frame repairs, you need to keep a eye on it for cracks starting. Frames flex a lot. You make a frame where it can't flex in a particular spot, it will break every time.
  12. Splindle cleaning

    I've used them. The seal actually spins inside itself instead of on the spindle. You can even put something like rtv on the spindle to help seal a less than perfect surface. You can also pretty much install them by hand, without having to drive them.
  13. 10 speed PTO

    I've been cleaning out the shop and found this PTO that came off a 10 speed Mack. Years ago the trans took a dump and I pulled the PTO before I got rid of it. Air shift. I'll take $300 plus the ride.
  14. You can weld flanges, such a lengthening a frame, but in most instances it's a bad idea. That's why I said "as a general rule". It's never a good idea, that I can think of, to drill a frame flange. To add a cross member as in the example above, the correct procedure would be to bolt it into the frame web. You'll have to weld the flange to fix that truck. It will do no good though if you don't remove that cross member first. What I'd personally do to fix that truck is remove the cross member, grind all that mess off, weld the frame up, and then have a frame piece formed that will fit inside the existing frame, and bolt it in. Other people have other ways but that's they way I've always fixed them and haven't had any problems.
  15. Here is a perfect example of people doing frame modifications that don't know what they are doing. https://www.govdeals.com/index.cfm?fa=Main.Item&itemid=352&acctid=1941 What they did was welded in a crossmember (to support a toolbox) and caused the frame to crack. Even looks like it has cracked before, and instead of getting rid of the problem, they just added more weld, which still didn't work. It all boils down to if you do a frame modification that can't flex, it will break every time. Also, as a general rule, you should avoid welding or drilling on frame flanges
