Standards for lifting slings
Lifting sling is one of the important devices in the lifting process of lifting machinery products. Common lifting slings include ring chain slings, wire rope slings, metal mesh slings and Four types of fiber slings are widely used in mining, metallurgy, shipbuilding, construction, transportation, aerospace, water conservancy, and hydropower industries.
In recent years, with the rapid development of China's economic construction, the demand for lifting slings has been increasing, and the number of manufacturing enterprises has continued to increase, and an independent industry has been formed. Because the product quality of lifting slings is directly related to the safety of personnel life and property, domestic and foreign companies attach great importance to this type of product and have formulated relevant sling standards. The International Organization for Standardization ISO / TC105 "Wire Rope Technical Committee" and ISO / TC111 "Steel Ring Chains, Hanging Chains, Components and Accessories Technical Committee" have also been established internationally. The scope of standardization includes wire rope slings and ring chains. Sling. The standard system for lifting slings in China is mainly established by translating international standards and advanced foreign standards.
With China's accession to the WTO, standardization has become increasingly important in international trade. Actively adopting international standards or advanced foreign standards can effectively improve the quality and technical level of Chinese products, reduce technical barriers in international trade, and enhance the international competitiveness of products. In the process of standard acquisition in China, considering that international standards are universal requirements in international trade, we choose to give priority to adopting international standards.
