AS 5229.1:2021 pdf download.Cranes – Tolerances for wheels and travel and traversing tracks Part 1: General (ISO 12488-1:2012, MOD).
This part of ISO 12488 specifies tolerances for construction assemblies and operational conditions of cranes and associated crane tracks as defined in ISO 4306-1. The purpose of the requirements in this part of ISO 12488 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 ISO 12488. 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 ISO 12488.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
construction tolerance
amount by which a specific dimension is permitted to vary, resulting from the assembly of the complete crane and its tracks, in new, modified, rebuilt or repaired buildings, before operational use
NOTE 1 This applies to new build or repaired or modified cranes and tracks
NOTE 2 The amount Is given either by the absolute value of the difference between the limits of size, or by the allowable geometric variation.
3.2 operational tolerance
amount by which a specific dimension is permitted to vary, resulting from the use of the crane and its tracks
NOTE The amount is given either by the absolute value of the difference between the limits of size, or by the allowable geometric variation.AS 5229.1 pdf download.
