Tensioner manufacturers lifting and lifting tools include: lifting hooks, wire ropes, slings, lifting chains, slings, self-service tensioners, lifting ropes, lifting skids, etc.

Now let's talk about this issue.

According to the manufacturing method, hooks can be divided into forged hooks and chip hooks.

Forged hooks can be divided into single hooks and double hooks.

Single hooks are usually used for small lifts and truck tensioners double hooks are usually used for larger lifts.

Chip hooks also have a hook and a double hook.

(1) single hook: This is a commonly used hook. Simple structure, easy to use. The material is usually made of 20 # high quality carbon steel or 20Mn, and the lifting weight does not exceed 80 tons.

(2) Double hook: When the lifting weight is large, use double hooks with uniform and symmetrical force. Material generally made of 20 # high quality carbon steel or 20Mn forging, lifting equipment above 80 tons is usually double hook.
