Abstract
Disclosed is a lifting hook with a self-locking function, the lifting hook comprising a hook body, wherein one end of the hook body is connected to a rope, and the other end thereof is provided with a U-shaped mounting end; a self-locking hook body is arranged on the mounting end by means of a ratchet wheel assembly, and the self-lock hook body is positioned on the mounting end so as to rotate; and the self-lock hook body is provided with an electric locking assembly, and when the hook body is in a state of bearing a heavy object, the electric locking assembly keeps the self-lock hook body in a fixed state. The self-locking hook body is designed to prevent the heavy object from falling off and causing damage. By designing the locking block assembly and the self-locking hook body, and byutilizing the characteristics of a ratchet wheel, the closing of the hook body is a one-way motion, such that the locking effect of the hook body is ensured.
