How do I choose the right hook or shackle for my lift?

Selection is based on the Working Load Limit (WLL), the type of connection (e.g., to a sling eye, chain, or direct to load), the environment, and required safety features (like latches or self-locking mechanisms). Our experts can assist you.

What is the difference between a screw pin shackle and a bolt-type shackle?

Screw pin shackles are common for quick or temporary connections where the pin may be frequently removed. Bolt-type shackles (with a nut and cotter pin) are more secure for permanent or long-term installations and where there's a risk of the pin rotating.

Can hooks and shackles be side-loaded?

Generally, hooks should be loaded in-line. Some shackles, particularly anchor/bow shackles, can accommodate angular loads, but always refer to manufacturer guidelines for load reduction factors.

How often should hooks and shackles be inspected?

Regular visual inspections should be done before each use. A thorough, documented inspection by a qualified person should occur periodically, typically annually or more frequently based on usage and environment, as per ASME standards.

Are there different material grades for hooks and shackles?

Yes, common materials include carbon steel and alloy steel. Alloy steel typically offers higher strength and better fatigue properties for demanding applications. Stainless steel is used for corrosion resistance.
