A coupling self-locking hook consisting of a hook annulus body having pivotably conjoined to its upper extent a hoisting shackle, the boom end of which has a plurality of upward facing openings that serve as a directional clamp slot and, furthermore, active rigging components of various specifications can be installed to the directional clamp slot and thereby provide for suspending and securing from different rigging components. After the hoisting shackle is rotated via a support point provided at a conjoinment position to the maximum angle, the press section of the hoisting shackle is pushed against the position lock of the body to maintain its active angle. The hoisting shackle of the self-locking hook can be secured to various types of active rigging components for increased practicality. |
