Hanging hooks are classified into single hooks and double hooks according to their shapes; and into forged hanging hooks and laminated hanging hooks according to their manufacturing methods.

　　Single hooks are simple to manufacture and easy to use, but their stress conditions are poor, so they are mostly used in workplaces with a lifting capacity of less than 80 tons. When the lifting capacity is large, symmetrically stressed double hooks are often used. Laminated hooks are made by riveting several cut steel plates together. If individual plates develop cracks, the entire hook will not break, providing good safety. However, they have a large self-weight and are mostly used on cranes with large lifting capacities or for lifting steel buckets. Hooks are often impacted during operation and must be made of high-quality carbon steel with good toughness.

　　Hanging hooks come in a wide range of categories, generally including: shackles, lifting rings, eyelets, pear-shaped rings, long lifting rings, combination lifting rings, S-shaped hooks, nose hooks, American-style hooks, claw hooks, eye-shaped slip hooks, lifting ring screws with safety clips, chain shackles. They are characterized by their uniqueness, novelty, quality, and safety, and are suitable for use in factories, mines, petroleum, chemical, and ship docks. They ensure safety, with a quality safety factor and a static load capacity of up to 3 times. The lifting capacity ranges from 5 tons to 150 tons.
