ISO 8686-4:2005 pdf free download.Cranes — Design principles for loads and load combinations — Part 4: Jib cranes.
ISO 8686-4:2005 applies the general design principles set forth in ISO 8686-1 to jib cranes, i.e. jib-type cranes other than those offshore, tower, mobile, railway, gantry and overhead cranes covered in other parts of ISO 8686-1, as defined in ISO 4306-1, and presents loads and load combinations appropriate for use in proof-of-competence calculations for the steel structures of jib cranes.
ISO 8686-4:2005 establishes requirements and gives guidance and design rules that reflect the present state of art in the field of crane machine design. The rules given represent good design practice that ensures fulfilment of essential safety requirements and adequate service life of components. Deviation from these rules normally could lead to increased risks or reduction of service life, but it is acknowledged that new technical innovations, materials, etc. can enable new solutions that result in equal or improved safety and durability.
