Rigging rings, also known as rotating rings, universal rings, universal ring screws, rotating rings, etc Mainly used for operations in special environments such as angled lifting and pulling 360 degree rotation in the horizontal direction can be achieved using a rotating lifting ring And 180 degree rotation in the up and down directions And the coefficient of breaking force in any direction shall not be less than 4 times Compared to fixed head rings such as DIN582 rings, rotating rings have flexible and multi-directional characteristics  In China, 35CrMo alloy steel and 42CrMo steel are generally used for manufacturing rotating lifting rings Products imported and exported are generally made of nickel chromium alloy steel materials
