Did you remember to whack the back of the cab with a grinder and tell your customer “Fuckked if I know how it happened” ????? Lol. My customer is me. I been watching me like a hawk. I’ll never get away with that.

This looks like a well thought out project. I'm not sure if i missed it or if it was mentioned, In all our triaxles that have air ride the dump valve is tied to the PTO so that as soon as the PTO is engaged the suspension is dumped. This is the Golden Rule with air suspension. Its unbelievable how little mud or dirt stuck in the front corner it takes to move the center of gravity over the frame and air in the suspension only helps then to roll er over. I'm sure driving this yourself that may seam extreme but the day you hire a driver you might want to think about it. One other note, the moment that the hoist begins to lift the load, the frame below the hoist takes a considerable amount of load for example a 6" hoist needing 2500 PSI to lift will exert 70650# against the frame, this is only for the initial as the dump body works on a diminishing load theory however most of our double frame Binders have had to have a repair and a 3rd section of rail added below the hoist. Our gross weights run a little higher here the same configuration at max here gets us 82830lbs or 37650kg. Nice Post RE: Dump Truck Build - ahub86 - 01-23-2021 (01-23-2021 )2dlb Wrote: Nice Job.

I have to agree there... any dump truck frame I have ever seen broken is near the hoist. Except for one time a local farmer forgot to unlatch the tailgate when he dumped. The load went to the back and the truck frame bent upwards. Like an upside down U Oops. I will take your advice and look into making the suspension dump with the PTO. I will be dumping it every time anyway, and that will keep me from forgetting. Thanks again. RE: Dump Truck Build - ahub86 - 04-09-2021 Well I figured I would give another little update to my project. Got the box painted and everything bolted back on. Had the shop that did the painting cut me out some old school stripes outta vinyl for the cab and hood. Had a local girl who runs a polishing business come down here and polish up the aluminum and stainless. Then she buffed the paint. She does an awesome job. I know that mostly this site is about repairs and maintenance and fuel mileage...but I am pretty proud of the way this one looks! I haven’t ever been too big on spending money on customization like lights or chrome, but I figured I went this far I might as well add some air cleaner lights and cab panels. I got it out on the road finally and hauled the first few loads with it this past week. I’ve only put about 300 miles on since I put it in service but I am already pretty happy. It’s comfortable and already I got better fuel mileage than the old Mack got, and I haven’t settled in and gotten comfortable driving yet. I don’t know if it was this thread or another I posted but Rawze brought up the gear ratio being a little fast for a dump truck. It has 3.91. I think Rawze is right. I can see where 3.91 rear ratio might be a little fast I can see me swapping out maybe getting down in the 4.33 range. If it was a new truck I coulda picked that but it’s hard to find a used truck that has EVERYTHING just right. I think I have a good start with this one. I will be putting the rear change on the back burner though because I have been spending money all winter it is time to bring in a few bucks with this thing!! RE: Dump Truck Build - SquareOne - 04-09-2021 Looks damn good! Don't ya wish it could make money just sitting there....almost hate to put dirt in the bed lol RE: Dump Truck Build - ahub86 - 04-09-2021 (04-09-2021 )SquareOne Wrote: Looks damn good!

All day on fresh road, slinging little stones up off my tires. I think I literally will cry. But that’s how I pay the bills! Toughen up and run it...right? |
