Different Latch Types on Safety Hooks-Stamped Latch vs. Cast Latch
26 Feb

In lifting and rigging operations, safety hooks are widely used to connect chains, wire ropes, and slings to loads. While the hook body carries the main load, the latch (also called the safety tongue) plays a crucial supporting role. Its function is to prevent accidental disengagement of the lifting component, reducing the risk of load release during handling.
