I think that the shaking of the trailer after a few feet on the road will release the tension of the strap and your theory doesn't apply. The fun is back guys!
Wrong. Just think about it. As the trailer shakes, the soil compresses down and tries to move outwards. This in fact increases the tension on the strap. It does not decrease as you suggest. In my days we used ropes and unless you used a special knot called a ‘trailer hitch’ the tension on the rope became so great due to this increased sideward pressure, it was impossible to undoe the knot.
Trust me. I learned this from years of experience. I also learned from bitter experience that stupidly, if you didn’t put these restraining straps on the trailer, outward pressure could burst open the side plates, spilling a load onto the road thus giving you untold trouble from the Police for having an insecure load.

I will have to give up. I am missing PhD in trucking and what you are saying, is way over my head. When the trailer shakes, the dirt due to a gravity and dynamic movement tends to spread in all direction, possibly drops off the trailer. The heap of the load is getting lower and lower. The tension of the strap is diminishing. At the end of your trip the strap is just a bow decoration on whatever is left from the pile of dirt. I also don't understand what you are talking about on previous page about "lateral" pressures and sides of the trailer bursting. Who knew that hauling a load of dirt is so sophisticated.

Sounds like an explanation Professor Irwin Corey might give us.

So, when you arrive at your destination get out your shovel and start unloading the dirt, which will surely decrease whatever tension exists on the straps. It's not rocket science.

There is a certain truth to what he is saying, when a load shifts it may indeed put increased tension on the straps, he however is over thinking it.

The dirt would have to move from outside of the strap underneath the strap and there are none of such forces, actually, the opposite is happening. The dirt is trying to move from the center to outward due to the shakes of the trailer and gravity of the dirt. Somebody should go back to school.

If you go back and read my reply carefully, you see that I said "load" and not dirt. Yes, I fully grasp the silliness of his statement. Just drive fast enough and all the dirt will blow away!

It doesn't matter what you call it, he must be smoking some funny cigarettes.

More than likely the person trying to secure the load of dirt was smoking something funny too! Probably dirtpusher!
