Pull tested another one of those breakaway sheaves today that's for a bigger sheave and a different design. Hook is rated at 4k and the sheave is as well.
29,383lbs and the metal tore. There was a 1.5"X1.5" .120 tube that's welded to 3/16" material.

Previous one I did straightened the hook out at about 28k but either way that's a far greater force then it will be exposed to.
