Product Description
Product Introduction
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 "master ring") and a secondary ring (the "slave ring"), which are flexibly connected via a pin or integrated forging. The surface undergoes galvanization or black oxide treatment to enhance its corrosion resistance. Its primary function is to facilitate multi-directional connections between lifting slings, heavy objects, and cranes. Typically, the main ring is attached to the crane hook, while the secondary ring can be used to secure wire ropes, chains, or other lifting attachments, making it suitable for lifting tasks at various angles. The rated working load ranges from 0.5 to 50 tons depending on the specific specifications, with a safety factor generally exceeding 4:1. Some models even meet the stringent European CE standards. This type of ring is widely employed in construction lifting, port handling, and industrial plant operations—particularly ideal for lifting irregularly shaped objects where adjusting the lifting angle is necessary. By effectively distributing the load, it significantly enhances operational safety.
