Component Specifications

Definition
A diagonal brace is a critical structural element in Roll-Over Protective Structures (ROPS) frames, designed to transfer lateral forces and moments through triangulation. It connects non-adjacent corners of rectangular frame sections, creating rigid triangles that resist shear, torsion, and buckling under operational and impact loads. In ROPS applications, it ensures structural integrity during roll-over incidents by maintaining frame geometry and preventing catastrophic collapse.
Working Principle
Works on the principle of triangulation in structural engineering, where diagonal members convert shear forces into axial tension or compression. When lateral forces act on the ROPS frame, the diagonal brace undergoes either tensile or compressive stress, distributing loads efficiently across the structure and preventing parallelogram deformation. This maintains the frame's rectangular shape under dynamic conditions.
Materials
High-strength low-alloy steel (HSLA) such as ASTM A572 Grade 50 or equivalent, with yield strength ≥345 MPa and tensile strength ≥450 MPa. May include carbon steel (e.g., ASTM A36) or advanced alloys for specialized applications. Surface treatments include hot-dip galvanizing or powder coating for corrosion resistance.
Technical Parameters
  • Angle Typically 30-60 degrees relative to horizontal
  • Length Customized to frame dimensions (typically 500-2000 mm)
  • Cross-section Rectangular or circular hollow section (RHS/CHS)
  • Load capacity Designed for specific ROPS standards (e.g., ISO 3471)
  • Wall thickness 3-10 mm depending on load requirements
  • Connection type Welded or bolted (with grade 8.8 or higher bolts)
Standards
ISO 3471, ISO 3449, SAE J1040, DIN EN 13510
