I don’t know how this compares, or if its apples and oranges….
But I have loaded many railroad cars with wheeled vehicles weighing over 40 tons and we use chain, and go to the vehicle frame not the axles to limit suspension travel.
I have never seen a chain failure in over 2500 vehicles. And for an additional reference point we use the same chain to hold down 70+ ton track vehicles, again without a single failure.
The same method is used on the boat, and that is a worse ride than ANY road in the country.
But on my car I use cargo straps cause they were cheaper, cleaner & easier for that application.
