Alloy steel anti-collision cover: formed into a solid body with a thickened anti-collision guard to protect the system from impacts and wear, increasing durability in demanding environments. Quenched and tempered G80 manganese steel chain: delivers high tensile strength with strong chain tension and a high safety factor, enhancing reliability under heavy loads. Precision-forged manganese steel hooks: upper and lower hooks made from tempered manganese steel for secure, non-slip engagement and long service life in rigging and lifting tasks. Reversible sprocket: enables smooth, snag-free chain engagement, reducing binding and improving operation efficiency. Benefits at a glance: - Robust load handling with a high safety factor and durable materials. - Secure connections thanks to precision forging and tempering. - Smooth, reliable operation with a reversible sprocket and anti-collision cover. - Compatible with standard G80 manganese steel chain systems and typical rigging setups. Typical use scenarios: - Lifting and rigging in manufacturing, maintenance bays, and crane operations where protection and reliability are critical. - Construction site rigging for moving heavy beams and equipment with minimized chain snagging. - Transport and load securing on trucks or trailers to prevent chain slip and improve safety during transit.
