I think the problem is not the rope hook but the ratchet strap. A ratchet strap is capable of exerting much more force on the hook than a rope, even with a couple of dollies tied in it. You can secure a light load onto a trailer with a ratchet strap & exceed the rating of the rope hook just by the tension on the strap. I.e. the ratchet strap puts more strain on the hook than the load. IMHO of course.
