Cross member/Transom Component – Other Transport Equipment Manufacturing

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
