Heavy-Duty Bow Shackles with Bolt, Nut & Safety Pin (2 Tonne to 85 Tonne)

Engineered for critical overhead lifting, multi-leg rigging, and long-term semi-permanent installations, these heavy-duty bow shackles (also known as anchor shackles) feature a safety bolt-and-nut retention system. Designed to handle safe working loads from 2 tonnes up to 85 tonnes, the wider "O" shaped bow design allows multi-directional loading without binding or side-point pinching the shackle body.

Key Features:

* Bolt, Nut & Safety Cotter Pin Design: The threaded bolt is secured with a heavy-duty nut and a steel split cotter pin, preventing the pin from backing out due to load rotation or continuous vibration.

* Wide Bow Design: Rounded shape accommodates multi-leg wire rope or synthetic webbing slings, enabling angled lifts without side-loading deformation.

* High-Tensile Forged Alloy Steel: Drop-forged, quenched, and tempered to withstand severe dynamic shock loads and extreme outdoor environments.

* Hot-Dip Galvanized Coating: Deep protective zinc finish provides long-term resistance against rust, saltwater corrosion, and harsh industrial atmospheric wear.

* International Safety Compliance: Manufactured and proof-tested to strictly meet global rigging standards (RR-C-271D Type IV / EN 13889 / ASME B30.26).

Applications:

* Permanent and semi-permanent overhead crane and gantry lifting assemblies

* Multi-leg sling connections for heavy machinery moving and structural steel erection

* Offshore oil & gas marine rigging, towing, and deep-water anchoring

* Heavy civil engineering and infrastructure development projects
