anyone ever reline a dump body

[racing01]

does anyone have any suggestions for relining a dump body it a steel body on a tandem mack its not too bad but its a bit worn and the floor is a little beat up it hauls everything from mulch to asphalt also thinking of plywood sides but not quite sure of the best way to fasten them in what thickness steel would be sufficient thanks

Our truck had plywood sides and it didnt take too long to tear them up. We haul a lot of rock though.

There is a company that makes plastic liners for dump trucks. To help materials slide out and protect the body.

I've never done it but I've seen it done. The guy just got 1/4" sheets of steel and welded them to the original floor.

We've done it. We threw in a sheet of 1/4" steel and welded it all the way around. Also, we plug welded it. Take the torches and burn a few holes in the middle and weld the sheet to the existing floor. This will prevent it from heaving.

thanks for everyones reply

on some old highway dumps we did the same, sheet steel welded around all sides and plug welded in the center. We also went up each side 2 ft. You say ahuling asphalt on ocassion.,... won't work long with plywood....

Not to hijack racing01's thread but, you guys mentioned hauling rock - What can you do to keep from tearing up a dump body when hauling a bunch of rip-rap or demo'ed concrete etc? I've heard of putting a layer of sand in the bed first, and somebody once told me about lining the bed with 3/4" plywood, (came with a story about going from rip rap to asphalt without removing the plywood - state roads inspector bent-up 2 temperature probes trying to push them into the body to check the asphalt temp.) Does anything work or is it a waste of time?

Well, if we are going to haul boulders, I will take a bucket of dirt and line the bottom before I place the boulders in the truck. Hauling rip rap, we don't do anything special. Man does that truck rock when getting loaded with R-5 :eek:

The new plastic liners are great. between $3000, and $6000 depending on thickness. They will holdup to the heat of asphalt and the ware of riprap. They last longer then steel and you do not have to tip the bed as much to dump making dumping safer. snow don't stick as much but will if you dump wet snow in a cold box. (like 20 degrees or below out and the snow is wet.) I beleave the only complaint is the inital price.

[Steve Frazier]

The plastic liners will not support themselves, so if the structural integrity of your floor is poor, the plastic liner will not last long. The only thing they are designed to do is prevent adhesion of the load to the body, not support the load in any way.

If i'm loading the large rock,using the backhoe's front bucket... I drop the tailgate & load 1 layer in, pushing the rocks forward...then i can dump the rest in over the side.

It all depends on the box construction if its a heavy built box to start with. You can do like the others said use 1/4 plate and plug weld it in the center if your hauling rock you need to weld angle iron to the floor so the the sharp edge is up /\ if you use 2x2 by 3/8s and space them 12"s apart and they run from the front right to the rear. The rock sits on the angle iron and does not hit the bottom of the box its the best way to beef up a box.

The rocks we put in the trucks weigh anywhere from 100lbs to 2000lbs or more and they are blasted rock boulders so the edges and points are sharp as h*ll they will punch through the side of a box real easy.

If you have been hauling asphalt already you may have one heck of a time welding the new steel into the box as the oil from the asphalt soaks into the steel really well. You may want to try steam clean or sand blast where you are going to weld.

We relined our dump a couple years ago with steel plate. It adds a lot of weight. I think that if I had it to do over again I would try one of the plastic, or rubber liners.

Now I know for a fact these liners are no where near those prices as I've looked into them.They come from 1/8 ''to 1/2'' thick,sold I believe in a 10' roll, and you pay by the foot.I can't find my prices right now but I remember it was well under $1K for my 10' bed.Hell,for $6K,you could put down road plate and never have worries again.

We relined out single axle last winter. I had the steel cut so that there was a seem in the center (2 seperate pieces). I also had the side bent on a 45, plus there was 6 inces above the bend so it went up the side about a foot. I just drove the truck to the steel shop to pick up the pieces and went right back to the shop. If you do it this way be sure to put something in at the top where the tailgate pins up to hold it apart. I didnt and it drew box together a bit and it was tough to get the gate up for a while. I didnt bother to plug weld, after a few loads of good sized stone, it's down and won't heav.

We always take the old florr out first, This serves 2 purposes If you dont usuallay the bed will sag quicker to your old floors dips. Secondly youll build up moisture and a little grit and it corrodes. we in pin the beds then roll them over and burn out the welds between the crossmembers. Usually go back with a 1/4 inch sheet. 1/4 T1 is best but about 1400. Im a firm believer in a liner. At the landfill we run our pan went down so we used a rolloff and a 20 yard dumpster The dirt just stuck so we had it lined 1/3 up trhe sides and on the bottom. Dirt just squirts out of it. Cost 2300 installed but there was alot of work to it. Makes a local contractor with 2 Granites mad he has Vibroters on the beds and every 3rd load they still have to scrape. Ive seen a few beds that are made from tubing and have a performed all poly skin that goes inside. I cant say enough about these liners as the rolloffs dont dump as steep as a dump bed and the stuff still comes out without jerking.
