Abstract
A method and apparatus for detecting overload distortion in lifting and the like gear is disclosed. The apparatus includes a hook with two reference points thereon defining, in the undistorted state of the hook, a reference dimension. The hook also has a standard dimension provided on the hook and conveniently accessible for reference purposes. The standard dimension is also a pair of points and one of this pair is coincident with one of the reference points thereby forming a triangle of points on the hook.
