The master-and-slave ring is a critical connecting lifting device used in hoisting operations. It is forged from alloy steel and consists of a main ring (the "mother ring") and a secondary ring (the "child ring"), which are flexibly connected via a pin shaft or integrated forging. The surface undergoes galvanization or black oxide treatment to enhance its corrosion resistance. Its primary function is to enable multi-directional connections between lifting slings, heavy objects, and cranes. Typically, the main ring is attached to the crane hook, while the child ring can be used to secure wire ropes, chains, or other lifting tools, making it suitable for multi-angle lifting tasks. The rated working load varies depending on the specific specifications, ranging from 0.5 to 50 tons. Most models achieve a safety factor of at least 4:1, with some even meeting the stringent European CE standards. This type of lifting ring is widely employed in construction hoisting, port handling, and industrial lifting applications. It is particularly well-suited for lifting irregularly shaped heavy objects that require adjustments to the lifting angle, effectively distributing forces and significantly improving operational safety.
