INDUSTRY COMPONENT

Cross member/Transom

Structural cross member connecting side frames in bogie frames to distribute loads and maintain geometry.

Component Specifications

Definition
A critical structural component in railway bogie frames that spans transversely between the two longitudinal side frames, providing torsional rigidity, load distribution, and maintaining the geometric integrity of the bogie assembly under dynamic operational stresses.
Working Principle
Functions as a rigid beam element that transfers vertical, lateral, and longitudinal forces between bogie side frames, resisting bending moments and torsion while maintaining prescribed wheelbase alignment and supporting secondary suspension components.
Materials
High-strength low-alloy steel (HSLA) grades such as ASTM A572 or EN 10025 S355, with yield strength 355-460 MPa, or forged steel for high-stress applications; thickness typically 12-25mm.
Technical Parameters
  • Width 200-350mm
  • Height 150-300mm
  • Length 1800-2500mm
  • Weight 80-200kg
  • Load Capacity 80-150kN static
  • Mounting Holes ISO M20-M24 bolts
Standards
ISO 1005, DIN 27201, EN 13749
