scope:

This part of ISO 12488 specifies tolerances for constructionassemblies and operational conditions of cranes and associatedcrane tracks as defined in ISO 4306-1. The purpose of therequirements in this part of ISO 12488 is to promote safe operationand achievement of the expected life of components by theelimination of excessive load effects due to deviations ormisalignments from the normal dimensions of the structure.Tolerances given are extreme values. The elastic deformations dueto load effects are outside the scope of this part of ISO 12488.These will need to be taken into account at the design stage usingother criteria to achieve the intended operation and performance.Specific values for particular crane types are given in other partsof ISO 12488.
