旋转吊环又称万向吊环或旋转吊环螺丝，用于有角度的特殊起吊场合。能实现水平360度旋转和上下180度翻转，任意方向四倍安全系数。相比传统的吊环螺丝（死吊环），更灵活、更能全方面满足起吊的需求。制作材质，国内多采用35CrMo合金钢和42CrMo合金钢，进口一般采用镍铬钼合金钢或100级材料。按与被吊物体连接方式可分为：螺孔型吊环与螺栓型吊环两种。按起吊角度可分为：直拉吊环，侧拉吊环，直侧拉通用型吊环。
Rotating lifting ring, also known as universal lifting ring or rotating lifting ring screw, is used for special lifting occasions with angle. It can realize 360 degree horizontal rotation and 180 degree up and down rotation, with four times the safety factor in any direction. Compared with the traditional lifting ring screw (dead lifting ring), it is more flexible and can meet the lifting requirements in all aspects. The manufacturing materials are mostly 35CrMo alloy steel and 42CrMo alloy steel in China, and generally Ni-Cr-Mo alloy steel or Grade 100 materials are used for import. According to the connection mode with the lifted object, it can be divided into two types: screw hole type lifting eye and bolt type lifting eye. According to the lifting angle, it can be divided into: straight pull lifting ring, side pull lifting ring and straight side pull universal lifting ring.
