Also known as universal rotating rings rings rings or rotary screw, for angled lifting special occasions. You can achieve the level of 360-degree rotation and 180 degrees vertically, compared with the conventional screw rings, more flexible and better meet all aspects of lifting needs. Production materials, domestic use of 35CrMn steel imports generally using nickel-chromium-molybdenum alloy steel or 100 material. Rally generally can be divided according to grade level G80 and G100 rotating rings. At present, Taiwan YOKE rotating rings to G80 level, Germany and Sweden GUNNEBO RUD level of G100. G100 class products Rally 25% higher than G80-class products, is currently on the market is relatively high-end products. Rotating rings bolt threads foreign products currently available metric two types of domestic-based multi-metric, inch thread due to the machining equipment is required, only a handful of manufacturers can supply, but the number of processing required. Rotating rings bolts of strength class 8.8 and 12.9, which imported 12.9 rotating rings to use more bolts, domestic rotating rings places 8.8 bolt majority. The latest data show that there are already foreign orders in accordance with the requirements of domestic manufacturers to develop a 12.9 rotating rings, form the shape of products from Germany, tend to work well. At present, the import of common brand rotating rings: (1) Germany RUD, early entry into the domestic market, higher visibility, supply specifications than the whole, expensive; (2) Sweden GUNNEBO, the world's main push G100 stage lifting accessories, kind than the whole, through BG certification, the rotating rings more by foreign or joint ventures that are designated as wind power generation equipment and mining machinery, specifications from M8-M48 are available from stock; (3) the United States JERGENS, major suppliers of various standard fixture parts for industrial customers, whose rotating rings to choose from a number of forms. (4) YOKE, Taiwan, the world's second largest manufacturer of hook rings, lifting accessories franchise G80 level. Its rotating rings main supply the European market, good price, supply specifications M8-M48, and China is now a large volume of equipment, about one week delivery period, lifting accessories brand is a good choice. With the vigorous development of the domestic mold industry, rotating rings to a great promotion and application, the main users of the mold factory and machinery factory, especially suitable for lifting large or sophisticated instruments and equipment.
