DIN ISO 4347:2011-07

This International Standard specifies the characteristics of chains used for general lifting purposes, together with the rim profiles of sheaves and the chain attachmens of clevises. It gives dimensions, limits for interchangeability, length measurement, preloading and minimum tensile strengths. This standard includes two series of chains: one derived from the ISO 606 A/ASME B29.8 series, designated by the symbol 'LH' or 'BL'; the other derived from the ISO 606 B series, designated by the symbol 'LL'.
