Repeated wheel-flange wear, rail-side contact, noise or lateral movement may indicate crane skewing rather than an isolated wheel problem. Replacing a worn wheel without identifying the cause can lead to rapid recurrence.
The assessment should consider runway straightness, level and parallelism; rail joints and fastening; bridge diagonal dimensions; wheel diameter and alignment; end-carriage geometry; bearing condition; drive synchronization; braking and structural deformation. Operating observations and current measurements can provide additional evidence.
Measurements should use a defined reference system and be compared with the crane design, applicable requirements and observed behaviour. Corrective work may involve runway, wheel, drive or structural actions, followed by repeat measurement and functional testing.
This content supports preliminary review. Equipment selection, structural calculations, compliance and commissioning decisions must be verified using site data and competent engineering.
