AS 5229.1 pdf download.Cranes — Tolerances for wheels and travel and traversing tracks
1 Scope
This part of ISO 12488 specifes tolerances for construction assemblies and operational conditions of cranes and associated crane tracks as defned 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. Specifc 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. 3.1 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. NOTE2 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.
4 Symbols A Tolerance of the span, related to the rail centre of travelling or traversing tracks, at each point of the track or to the wheel centre of crabs or cranes B Tolerance of the horizontal straightness, in ground plan, at each point of the travelling track b Tolerance of horizontal straightness related to a test length of 2 m in ground plan, (sample value) at each point of the rail head C Tolerance of straightness related to the height of the crane rail centre at each point of the travelling track c Tolerance of straightness related to a test length of 2 m (sample value) at each point of height of the crane rail a Centre-to-centre distance between the horizontal guide rollers, in longitudinal direction of rail e Centre-to-centre distance between two wheels or bogeys, in longitudinal direction of rail h F Distance between the top edge of a rail and the bottom edge of horizontal guide rollers S Span from centre to centre of the rail 0/00 Angle of inclination expressed as vertical points per horizontal thousand D Wheel diameter E Height tolerance related to opposite measuring points at right angles to each point of the track F Parallelism tolerance of end stops or buffers G Angularity tolerance related to rail cross-section with plane surface H F Vertical offset of a welded connection H S Horizontal offset of a rail head K Parallelism tolerance of a rail with reference to the web ΔD Diameter tolerance for coupled and independently driven crane/cab wheels Δe Tolerance of the wheel base in ground plan ΔF Alignment tolerance of guide rollers in ground plan Δhr Height tolerance of the points of wheel contact ΔN Tolerance of parallel offset of the wheels in ground plan α F Axle tolerance of parallelism of guide rollers across the track β F Axle tolerance of parallelism of guide rollers across the track ϕ k Axle tolerance of parallelism in a ground plan of the hole (inclination of axis) ϕ r Axle tolerance of parallelism in a ground plan of the wheel (inclination of wheel)
