Mounting A V Box

The last time we got to salt, one of our subs got a new 4 yd V box spreader. They put it in a single axle 5 yd dump. Loaded it up and started spreading. About 1/2 way through one of the lots, I see the salt truck coming my way, and then he just stopped. There was no obvoius reason to stop. I took a ride over to see why he stopped, and at the same time he started going again. I could see he was on the phone. He turned into one of the rows, and I saw what the problem was. The nearly full V box in the back had tipped over to one side. I pulled up to talk to the driver. The first thing he said was "Our %#&)^^ welder said the straps would hold it. I knew they wouldn't, I said we needed chains". Now it would take a loader to upright it again. He got out of the truck, and we both walked around the back to look at the spreader, and make sure it wasn't leaking fluids. It was wedged in there pretty good. Then I saw what I think was the real problem. The spreader was just sitting in the body. There was no wood bolted to the bottom of the spreader. Even small 1 yard V boxes I see with at least a 2x4 bolted across the bottom. With the 4 yard, I would expect at least two 4x4's, if not 3 bolted across the bottom to help stabilize it in the body. Heaped up, he probably had close to 5 yards in the spreader, up that high, the straps couldn't handle the load. I saw them, and they were pretty heavy 2" ratchet binders on one side.... on the other side, they had fallen off somewhere. One of the pickups found them later on, and the straps weren't broken. So I assume they let go somehow.

So I guess the moral is to use chains and ratchet chain binders to mount your spreaders.

I have two oak 2x4s bolted to the bottom of my 2 yd sander on a flatbed. Also 2" straps on each corner. I found that the straps loosened after about ten hours. So much that one came completely loose and I could see it in the rearview mirror. Lucky I caught it before I had the same problem. Ratchets still worked well and haven't had any problem since, so I just figured it was "settling". I would think that with that much weight (five yards) relying on straps is not the best idea.

I just checked my Vbox and another strap was hanging loose. I'll be going to chain binders.

I don't know what "the law" is in your area, but here in Ontario I believe that if you're using chains to secure something in your truck, they need to be at least Tranport Grade 70. Granted, that's from my experience pulling a flatbed trailer, not sure if it's a big deal with a spreader in the back of a truck.

Just make sure you get the ratchet style chain binders as opposed to the over-centre (a.k.a. "bear trap") type.

Every set of directions I have ever seen for a v-box call for it to be bolted to the floor of the bed and then strapped in as well. I know of very few people who do bolt them in though. It is a good idea to put a block in the front as well so that the spreader does not slide forward into the back of the cab.

I bolted a six inch channel to the back of mine and welded 1" pins to the ends of it so they would get clamped in by the tailgate dogs. Then I welded two D rings to the dump floor in the front corners and use 3" rachet straps to cinch the front down. It's never come loose in 5 years use.

My buddy has heavy gauge threaded rod and turnbuckles that are pinned to the sideboard pockets of his truck, that seems to work too.

In my real job (cop) you would be surprised at the amount of times things come falling,rolling,spinning,breaking off trailers and trucks.

Sometimes it is just the bad luck where they had to swerve for other traffic/hazard. You would hate to see some of the things
that happen when things go flying, and most things come
forward!!!!! (good idea for headache racks).

One thing that everyone may want to check is that even if
you are mounted through the flat bed, double check everyonce
in a while the mounts underneath, some are made from wood
and easily crack or simply wear out from moisture, or the flatbed
wood worn out.

Finally, whatever mount you have should protect you, and made
to stop the entire load even if the vehicle rolls, especially if you
have lots of steep terrain.

Once saw a V-box mounted on a 1-ton flatbed (loaded) and
only hooked down with bungee cords
