Runway acceptance values can vary with crane type, span, wheel arrangement, rail profile, structure and the applicable design or inspection basis. A tolerance table found in isolation should not be applied to every crane without context.
A survey may record straightness, level, gauge, parallelism, joints, rail-head condition and fastening using a defined reference system. Temperature, structural deflection and instrument accuracy can influence the results and should be documented.
The measurements should be interpreted together with crane travel behaviour, wheel marks, drive current, noise and wear history. Corrective work should be followed by repeat measurement and controlled functional testing.
This content supports preliminary review. Equipment selection, structural calculations, compliance and commissioning decisions must be verified using site data and competent engineering.
