1-1/4″ Screw Type Shackle – Standard Curved Shackle with Safety Screw, Nominal Working Load (WLL) 12 Tons, Curved Anchor/Lyre Type Shackle
3/8″ shackle ideal for moving light to moderate loads. With a compact and durable design, it is perfect for use in workshops, warehouses, and small constructions.
Product Description
Our screw-type curved shackle is a high-quality shackle with a safety pin designed for secure lifting and rigging applications. Each shackle is made from tempered and quenched materials, featuring a durable carbon steel shackle body and an alloy steel pin to ensure long-term performance and reliability.
Curved shackles, commonly known as anchor shackles, are typically used in lifting and rigging systems. They are characterized by their wide, rounded "O"-shaped body, which allows them to be used for multiple sling leg connections or to support side loads.
Screw-type shackles offer enhanced safety through a combination of screw, nut, and cotter pin. This design prevents accidental loosening of the pin, making them ideal for situations that require strong safety features. Screw-type shackles are suitable for single and multi-leg configurations, offering versatility and safety even in rotation or twisting situations.
These shackles are ideal for applications that require a round pin or a screw pin, as they remain locked even when subjected to rotational forces. The galvanizing process ensures that the shackles are highly durable and corrosion-resistant, providing long-term reliability for various tie-down applications.
Screw-type shackles are particularly useful in semi-permanent installations or situations where the load may cause the shackle pin to rotate. The safety screw, nut, and cotter pin eliminate the need for continuous retightening, making them an excellent choice for prolonged use.
Main Features:
- Made with tempered and tempered carbon steel and alloy steel pin for maximum strength.
- The curvature is hot-dip galvanized. The pins have a standard yellow paint finish, with customization options available upon request.
- In compliance with ASME B30.26-2004 and RR-C-271D standards (or equivalents).
- The proof load is twice the working load limit (WLL), while the minimum breaking load is six times the WLL, respectively.
