Innovative lifting point, Higher strength.
New type lifting point make your loading more safety！
Good force structure. Contract with traditional DIN 580 eyebolt, it eliminate torque,have the same direction with the load object all time,consistently bearing load well.
Choose 42 CrMo alloy steel after forging and High Strength Quenched,heat treatment,parkerising process.
Variety of specifications. Our standard specification accoring the Installation standards. Yiyun also welcome customization.
Quality guarantee. 4 times safety factor, equal tensile force WLL on different direction. 100% individually breakage Inspected with certification, every thread will pass GO - NO GO FIXED GAUGES before packing, and individually proof test at 2.5 times Working load limit Fatigue tested at 1.5 times Working Load Limit for 20000 cycles.
Universal swivel hoist ring
More specification, widely application, popular choose by clients. Hexagonal bolt head design are easy for Install and tight with the object.
YDS swivel hoist ring
