A lifting butterfly buckle, also called a lifting hook, is a tool used for lifting goods. It usually consists of two interconnected curved hooks with a length of chain or rope in between. During operation, the lifting butterfly buckle passes the chain or rope through the lifting ring or lifting lug of the cargo, and then lifts it through the wire rope on the crane or lifting equipment. The lifting butterfly buckle is widely used in construction, bridge, wharf, and other projects, and is an important lifting tool.
