Heavy-Duty First-Grade Shackle , Iran
The heavy-duty first-grade shackle is a critical industrial connector for lifting and crane operations, capable of handling loads up to 30 tons. It is made of alloy steel with tensile strength of 800–1100 MPa and surface hardness of 35–45 HRC. The standard U-shaped or D-shaped design with precision machining ensures uniform stress distribution and reduces force concentration. Surfaces are coated with hot-dip galvanization or industrial paint for enhanced corrosion, rust, and wear resistance. Standard safety factors range from 4:1 to 5:1, providing high dynamic and static load capacity.
Structurally, the heavy-duty shackle includes a main body and a hardened pin with precise threading for secure connection to chains, cables, wire ropes, or hooks. Engineered pin and body design prevents accidental loosening or slippage. Pins are forged or machined for high compressive strength. These shackles are widely used in oil, gas, steel, construction, and port industries, offering stable performance in operating temperatures from −40°C to +200°C.You can order and buy Heavy-Duty First-Grade Shackle from Iran by contacting us through whatsaap and email.

Applications of Heavy-Duty Shackles in Hoists, Cranes, and Slings
Heavy-duty shackles, due to their high load capacity and mechanical strength, are key components in hoists, cranes, and slings. In hoists and cranes, they connect loads to hooks or wire ropes, allowing safe lifting of heavy loads up to several tons. In slings, heavy-duty shackles enable multi-leg wire rope or chain connections, ensuring uniform stress distribution. Using standard shackles with proper safety factor, corrosion resistance, and protective coating enhances operator safety and lifting equipment durability.
