Pay attention to the long haul 18 wheelers. The large 4" wide straps with heavy steel (not hooks) ends are common. The ratchets are available at my TSC and other stores to be welded or bolted on to your trailer or convenient location. They usually tighten with a tire iron or similar and are made of 3/8" steel or better. But those same gurus driving 18 wheelers also seem to nearly always use chain and tighteners for tractors and heavy steel stuff as opposed to boards and bags and packages. I am told the old over-center chain tighteners are no longer "legal" and one must use the PITA threaded turning type. I throw out a few points of opinion not caring where they fall ...
1) I've never been stopped while hauling in 30 years of not very frequent experience. Doubt I ever will be.
2) DOT inspectors are looking mainly for obvious offenders, not you guys trying to move a farm tractor. They are in general not going to bother you.
3) Serious day-in-day-out haulers pick their tie downs based on what they are hauling. Straps if they work well, chains if they think it is better.
4) I do not give a crap what DOT inspectors or State Police or other patrol folks think or do. Worst case I pay their fines. What I really care about is that the load I am hauling is not going to come through the cab at me. And secondarily that it not be bouncing loose around the trailer bed. So the chain or the straps I choose are based on the weight of the object that may be moving at 70 mph in my rearview mirror when I hit something. If my own criteria is met, the inspectors criteria will also be met and exceeded in almost every case. Honestly I do not care what their criteria is, I care about protecting me and that automatically protects others nearby.
