Projects

We specialize in high-performance Finite Element Analysis (FEA) for heavy machinery components, including drawbars used in Caterpillar motor graders. These components endure constant cyclic loading in harsh environments—making fatigue life analysis critical for safety, performance, and reliability.

Our fatigue analysis service helps you understand how the drawbar behaves over time under real-world conditions—identifying potential failure points before they become costly issues.

Our drawbar fatigue analysis process includes:

• Detailed 3D Modeling & Meshing
  We create or refine accurate CAD models of the drawbar, focusing on welds, fillets, bolt holes, and other high-stress areas.
   
• Load Case Definition
  Realistic service load cases are simulated, including drawbar pulling forces, articulation, dynamic terrain-induced loading, and vibrational effects from rough grading surfaces.
   
• Static & Dynamic Stress Analysis
  We evaluate stress concentration zones through linear or nonlinear simulations, as needed, ensuring the model reflects true mechanical behavior.
   
• Fatigue Life Prediction
  Using strain-life or stress-life approaches (e.g., SN/EN curves), we estimate the number of cycles to failure for key locations—factoring in material properties, weld details, and surface treatments.
   
• Result Interpretation & Recommendations
  Clear, actionable insights are provided, including critical stress zones, fatigue hotspots, and design modification suggestions to improve lifespan and reduce maintenance.
   
• RPEQ-Certified Reporting
  All findings can be compiled in a professional, certifiable report, compliant with engineering standards and ready for review by OEMs or regulators

 This type of analysis is ideal for OEM component validation, aftermarket upgrade design, or failure investigation. If you're developing or assessing a drawbar design for Caterpillar or similar motor graders, our FEA service helps you build it smarter, safer, and tougher. 

 We provide expert Finite Element Analysis (FEA) and engineering certification services for industrial jib swing cranes—ensuring your lifting equipment is safe, compliant, and built to perform under real-world demands.

Jib cranes often operate in tight spaces and handle dynamic, repetitive loading. Our FEA services help verify structural integrity, optimise design, and support certification requirements with confidence.

1. Structural FEA Simulation

• Simulate the jib arm, column, baseplate, and mounting interface under rated load conditions.
   
• Assess deflection, stress concentrations, and load paths during swing, lift, and hold operations.
   
• Model worst-case scenarios such as load eccentricity, sudden stops, or overload.
   

2. Welds & Connection Analysis

• Check fatigue-prone areas like pivot points, weld seams, and baseplate anchors.
   
• Evaluate bolt group strength and plate stiffness under rotation and lifting moments.
   

3. Compliance Verification

• Validate against applicable Australian Standards (e.g., AS 1418, AS 4100, AS/NZS 1170) and manufacturer requirements.
   
• Identify and address areas of non-compliance prior to fabrication or installation.
   

4. Fatigue Life Estimation

• Calculate expected service life under typical and extreme duty cycles.
   
• Highlight critical fatigue zones for improved design or inspection scheduling.
   

5. RPEQ Certification

• Provide a detailed, RPEQ-signed engineering report covering the analysis, design verification, safety factors, and compliance notes.
   
• Ready for submission to regulatory authorities, clients, or insurers.
   

We work closely with fabricators, plant managers, and engineering teams to ensure your jib crane design is efficient, safe, and ready to lift with confidence. Whether it's a new install, retrofit, or failure investigation—we’ve got you covered.

Need help with lifting lugs, mobile frames, or wall-mounted cranes too? Just let us know—we’re here to help with practical engineering solutions that meet the mark.
