Project Overview
A top US construction equipment manufacturer hired Yas Tech. Services to design a linkage system for their next-generation backhoe loader, targeting improved performance, durability, and maintainability. We delivered a complete solution from concept to production, meeting client and industry standards.
Concept Design
We used CAD software to optimize the linkage system connecting the boom, dipper, and bucket, introducing a modular design for quick part swaps and less downtime.
Design Calculations
We performed:
- Load Analysis: Assessed forces during digging and lifting.
- Kinematic Analysis: Confirmed motion and positioning.
- Material Strength: Chose cost-effective, durable materials.
Stress Analysis
Finite Element Analysis (FEA) pinpointed and reinforced weak spots, ensuring the linkage met safety requirements for heavy-duty use.
Hydraulic Cylinder Calculation and Selection
We calculated cylinder specs for capacity, speed, pressure, and stroke, selecting reliable units with optimized mounting for efficiency.
Prototyping
Partnering with a fabrication facility, we built and tested prototypes with load and cycle tests, verifying performance and durability.
Key Challenges
- Strength vs. Weight: Balanced load resistance and lightweight design.
- Modular Tolerances: Ensured precision with GD&T.
- Hydraulic Integration: Fixed alignment for consistent operation.
Manufacturing Drawings
Detailed drawings with GD&T and tolerance stackup analysis ensured accurate Serial production and assembly.
Regulatory Standards
We complied with:
- ASME B30.22: Boom design safety.
- ASTM Standards: Material strength.
- OSHA Requirements: Operator and equipment safety.
Conclusion
We delivered a high-performing, modular linkage system, showcasing our end-to-end design expertise and exceeding client goals.
