Product Description
Product Introduction
Double-loop shackles, also known as double-ring connecting shackles, are crucial 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. Primarily used for connecting wire ropes, chains, and other lifting slings to hooks or heavy objects, these shackles allow 360° rotation, effectively preventing sling twisting and knotting while minimizing operational wear and tear. Product specifications are categorized according to load capacity, ranging from lightweight models capable of handling loads up to 0.3 tons to heavy-duty versions designed for capacities as high as 100 tons. The surface finish typically includes polishing and corrosion-resistant treatments to enhance durability and extend service life. Widely employed in demanding heavy-lifting applications such as bridge construction, shipbuilding, and mining operations, these shackles offer convenient installation and removal. Additionally, they come equipped with safety locking pins to prevent accidental disengagement, ensuring stable and secure connections even under complex working conditions, thereby maintaining safe and controlled operations throughout the entire lifting process.
