标准摘要
[中文适用范围]： 本文件规定了 8 级单腿、双腿、三腿和四腿焊接链吊索的要求、评级和测试方法，使用的部件包括符合 ISO 3076 的吊链以及符合 ISO 16798 的链节、符合 ISO 7597 的吊钩和锻造部件符合 ISO 8539 标准。 注 1：对于本文件未涵盖的特殊起重用途，可以额外使用中间连杆，例如将具有不同工作负载限制的部件相互连接。 本文件涵盖的公称直径 dn 范围为 4 毫米至 45 毫米。 根据 ISO 3056，本文件中的链条吊索适用于 –40 °C 至 +400 °C 的温度范围。 注 2：关于 8 级链条吊索的使用和维护，请参见 ISO 3056。 符合该标准的链条吊索文件符合 ISO 1834 的一般验收条件，仅用于对称分布的载荷。 注3：对于具有不对称分布载荷的链条吊索的额定值，参见ISO 3056。 本文件不适用于机械连接的链条吊索。 注 4：对于机械连接的链条吊索，参见 ISO 7593。 [外文原描述]： This document specifies the requirements, methods of rating and testing of single, double, three and four leg welded chain slings of grade 8 using components such as sling chains according to ISO 3076 together with links according to ISO 16798, hooks according to ISO 7597 and forged components according to ISO 8539. NOTE 1 For special lifting purposes not covered by this document, additionally intermediate links can be used, for example to connect components to each other having different working load limit. The range of nominal diameter, d n , covered by this document is from 4 mm to 45 mm. Chain slings according to this document are for use in the temperature range ?40 °C to +400 °C according to ISO 3056. NOTE 2 Concerning the use and maintenance of chain slings of grade 8, see ISO 3056. Chain slings according to this document comply with the general conditions of acceptance of ISO 1834 and are used for symmetrically distributed loads only. NOTE 3 For rating of chain slings with asymmetrically distributed loads, see ISO 3056. This document does not apply to mechanically joined chain slings. NOTE 4 For mechanically joined chain slings, see ISO 7593.
