Purpose of ASME B30.26-2015

The core purpose of this volume is to establish safety and performance criteria for the small but critical components used daily in rigging operations. It ensures that this hardware possesses the necessary ductility, design factors, and proof load capabilities to reliably withstand the forces generated during overhead lifting.

The standard achieves safety by:

  • Providing construction specifications and marking requirements (Rated Load, Manufacturer ID) for each piece of hardware.
  • Defining specific removal from service criteria (what visual damage means the item is unsafe) to prevent catastrophic failures.
  • Detailing working load limit (WLL) reduction guidelines, especially when hardware is exposed to angular loading (like non-straight pulls on an eyebolt).

What is it Used For?

ASME B30.26-2015 is a foundational document for any rigger, crane operator, safety manager, or equipment owner who procures, uses, or maintains lifting gear. It governs common, detachable hardware, including:

  • Shackles (used to connect slings, hooks, or chains).
  • Eyebolts and Hoist Rings (used as connection points on the load).
  • Links, Master Links, and Rings (central connection points for multi-leg slings).
  • Turnbuckles (used for tensioning and length adjustment).
  • Wire Rope Clips and Wedge Sockets (used for making end terminations on wire rope).

The primary applications are:

  • Inspection Practices: It dictates the frequent (daily/weekly) and periodic (annual) inspection requirements and provides the specific dimensional tolerances for when a component, such as a shackle, must be permanently retired.
  • Safe Rigging Practices: It is used to calculate the necessary derating of hardware capacity when the load is applied at an angle, guiding riggers to adjust their lifts safely.
