ISO 16625-2013 pdf free download.Cranes and hoists – Selection of wire ropes, drums and sheaves.
ISO 16625 specifies the minimum practical design factors, Zr,, for the various classifications of mechanism, rope types, rope duties and types of spooling and demonstrates how these are used in the determination of the minimum breaking force of the wire rope.
It specifies the selection factors for drums and sheaves for the various classifications of mechanisms, rope types and rope duties and how these are used in the determination of the minimum practical diameters of drums and sheaves that work in association with the selected wire rope.
A list of types of cranes and hoists to which this standard applies is given in Annex A.
Annex B gives factors, additional to those mentioned above, which might need consideration when
selecting the wire rope and associated equipment.
