FAQ

Working Load Limit (WLL) is the maximum load that rigging equipment is rated to handle under specified operating conditions. Breaking strength refers to the force at which a component fails during testing. Breaking strength is generally higher than WLL because a design factor is applied. Buyers should always select rigging hardware based on its rated WLL and the actual loading conditions, rather than using breaking strength as the allowable working load.

To select the correct lifting shackle size, consider the load weight, required WLL, pin diameter, body dimensions, and connection points. The shackle must fit the connected sling, hook, or lifting attachment without creating improper loading. Buyers should also check the manufacturer's specifications for loading angles and operating limitations. AY Rigging supplies various bow shackles for lifting, rigging, and industrial applications.
