Semi truck strap binder versus human jaw

That binder rachet looks like it was bolted to the side of the trailer, I dont see any broken welds
Ive worked on a lot of heavy trucks and equipment and cant recall any being bolted
Im no engineer but bolted leaves IMO a lot to be desired, the pull is not straight on
If it was welded, who ever welded it shouldn't be welding.....A proper weld would have resulted in the whole piece off the trailer side ripping out
The bottom weld on that bracket would be most of the strength, if that weld failed the top weld would eventually hinge right off....But again I dont really know how that rachet is attached
