Double-loop shackles, also known as double-ring connecting shackles, are critical components in lifting slings and rigging systems. They are crafted from alloy steel through precision die-forging processes, featuring a symmetrical dual-loop design with scientifically engineered arc curvature to ensure even load distribution. These shackles are primarily used to connect wire ropes, chains, and other lifting slings to hooks or heavy objects, enabling 360° rotation to prevent twisting and knotting of the slings, thereby minimizing operational wear and tear. Product specifications are categorized according to their load capacities, ranging from lightweight models rated at 0.3 tons up to heavy-duty versions capable of handling loads as high as 100 tons. The surface finish typically includes polishing and corrosion-resistant treatments to enhance durability and extend service life. Double-loop shackles are widely employed in demanding heavy-lifting applications such as bridge construction, shipbuilding, and mining operations. They offer convenient installation and removal while being equipped with safety detent pins to prevent accidental disengagement. This ensures stable and secure connections even under complex working conditions, guaranteeing safe and controlled handling of heavy loads throughout the lifting process.
