Describes tolerances for construction assemblies and operational conditions of cranes and associated crane tracks as defined in ISO 4306-1.

This part of ISO12488 specifies tolerances for construction assemblies and operational conditions of cranes and associated crane tracks as defined in ISO4306-1. The purpose of the requirements in this part of ISO12488 is to promote safe operation and achievement of the expected life of components by the elimination of excessive load effects due to deviations or misalignments from the normal dimensions of the structure.

Tolerances given are extreme values. The elastic deformations due to load effects are outside the scope of this part of ISO12488. These will need to be taken into account at the design stage using other criteria to achieve the intended operation and performance.

Specific values for particular crane types are given in other parts of ISO12488.
