Abstract
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.
Claims3
A coupling self-locking hook comprised of a hook annulus body and a pivot pin inserted into a hoisting shackle at the upper extent of the body, of which:
- The said body has formed in its upper lateral face a horizontally recessed U-shaped clevis section and, furthermore, situated inside the said U-shaped clevis section is a position lock.
- The said hoisting shackle has formed in its boom end a plurality of upward facing openings and, furthermore, these serve as a directional clamp slot that provides for the installation of various active rigging components, with all the partition layers of the said directional clamp slot having formed in them a through-hole.
- Since various active rigging components can be installed to the said boom end of the said hoisting shackle, the said self-locking hook of the present invention is suitable for applications in which active rigging components need to be installed for different situations and thereby achieves a coupling self-locking hook of high practicality.
