DIN ISO 4347:2018
Leaf chains, clevises and sheaves - Dimensions, measuring forces, tensile strengths and dynamic strengths (ISO 4347:2015)
This standard is a translation of the fifth edition of ISO 4347:2015 and specifies the characteristics of leaf chains used for general lifting purposes, together with the rim profiles of sheaves and the chain attachment ends of clevises. It gives dimensions, limits for interchangeability, length measurement, preloading, minimum tensile strengths and minimum dynamic strengths. In informative Annexes a method of calculating minimum dynamic strengths and a method of determining maximum test force Fmax when conducting the dynamic strength conformance test according ISO 15654:2015 are given.
