AI Technical Summary
The existing hooks have poor steel bolt strength and are inconvenient to replace, which makes the wire rope easy to fall off. The existing torsion spring structure hooks require cutting the pin shaft for replacement, which is also inconvenient.
The hook adopts a limit pin and spring structure. By setting a locking block and a locking groove on the hook body and the support block, the spring force is used to make the locking block lock into the locking groove, thereby locking the hook at the bottom of the hook. The limit pin has high strength and is easy to replace.
It improves the strength of the hook, prevents the wire rope from falling off, and simplifies the operation and replacement process of the limit pin.
