ISO 4347:2015

Leaf chains, clevises and sheaves — Dimensions, measuring forces, tensile strengths and dynamic strengths

ISO 4347:2015 specifies the characteristics of 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.
