BS ISO 4347:2015 pdf download – Leaf chains, clevises and sheaves — Dimensions, measuring forces, tensile strengths and dynamic strengths
This International Standard 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.
