The Grade 80 European Type Master Link Assembly (MAU Type) is a high-strength alloy steel head-ring equipped with two intermediate sub-links. It is engineered specifically to serve as the upper terminal for 3-leg and 4-leg chain sling assemblies, fully complying with EN 1677-4 and EN 818 standards.
The MAU Master Link Assembly is the standard European head-ring configuration for constructing heavy-duty 3-leg and 4-leg chain slings. Featuring a primary master link with two intermediate sub-links, it ensures proper multi-point load distribution and prevents the crowding of connecting hardware at the crane hook.
| Size Range | Method | Performance Benefit |
|---|---|---|
| Small to Medium (6mm - 18mm) |
Flash Butt Welded | High-quality welded construction. Ensures consistent tensile strength and offers a highly cost-effective solution for standard capacities. |
| Large Sizes (20mm and above) |
Drop Forged Main Link | The massive primary master link is Drop Forged for superior structural integrity in extreme heavy-lift scenarios, while the intermediate sub-links remain welded. |
