This International Standard sets forth general conditions, requirements, methods and parameter values forperforming proof-of-competence determinations of the steel structures of cranes based upon the limit statemethod. It is intended to be used together with the loads and load combinations of the applicable parts ofISO 8686.This International Standard is general and covers cranes of all types. Other International Standards may givespecific proof-of-competence requirements for particular crane types.Proofs of competence, by theoretical calculations and/or testing, are intended to prevent hazards related tothe performance of the structure by establishing the limits of strength, e.g. yield, ultimate, fatigue, brittlefracture.According to ISO 8686-1, there are two general approaches to proof-of-competence calculations: the limitstate method employing partial safety factors, and the allowable stress method employing a global safetyfactor. The allowable stress method is a permitted alternative to the limit state method as set forth in thisInternational Standard.Proof-of-competence calculations for components of accessories (e.g. hand rails, stairs, walkways, cabins)are not covered by this International Standard. However, the influence of such attachments on the mainstructure needs to be considered.
