The Crosby S319 Hoist Shank Hooks from 500kg to 75 tonnes incorporate markings forged into the product which address two (2) QUIC-CHECK features. They are supplied designed with deformation indicators - two strategically placed marks, one just below the shank or eye and the other on the hook up, which allows for a QUIC-CHECK measurement to determine if the throat opening has changed, thus indicating abuse or overload.
