Semi truck strap binder versus human jaw

The picture you posted was of a aluminium trailer. The trailers ive replaced ratchet's on were all heavier duty, the ratchets were thicker steel
In fact not long ago I cut one off that was bent up and the owner was not using it and wanted it off. It was made out of 3/8 steel
Many dont even use straps or ratchets, they use chain and binders that catch a flat bar on the trailer sides

That photo was just the best angle. There's similar steel trailers out there too.
