Crane girder structures — fabricated runway beams and support steel for EOT cranes
Crane girder structures are the fabricated steel runway beams, columns, brackets, and tie beams that support electric overhead travelling (EOT) cranes in factories, warehouses, and process buildings. Runway beams must meet deflection and fatigue requirements under IS 807:2006 in addition to general fabrication rules in IS 800:2007. Sun Corporation fabricates crane girders as built-up plate beams or heavy rolled sections, with alignment critical for crane vendor handover.
Fabrication scope
| Component | Notes |
|---|---|
| Runway beams | Built-up or UB sections; camber as designed |
| Crane columns and brackets | Built-up or rolled; cap plates for beam seating |
| Tie beams and bracing | Longitudinal stability between crane columns |
| Rail clips and sole plates | When shown on structural drawings |
| Design basis | IS 807:2006 for crane loads; IS 800 for connections |
| Erection survey | Span, elevation, and straightness checked before crane install |
Coordination with crane supplier
We are a structural steel fabricator, not a crane OEM. Our scope ends at correctly positioned, plumb runway steel ready for the crane supplier’s rail and electrification work. Crane load data and wheel loads must be on the structural design drawings before shop drawing release. For built-up spans, see built-up beam fabrication.
