Quality Assurance for Excavator Long Arms

We maintain uncompromising quality standards through meticulous material selection and precision engineering:

Premium Material Specifications:

• Structural Components: Certified Q355B & Q690D steel from Shaogang Steel

• Hydraulic Systems: National standard seamless pipes for flawless fluid dynamics

• Critical Wear Parts:

  • 40MuCr alloy pins for superior shear resistance

  • 4-layer steel wire reinforced hydraulic hoses

  • Graphite-impregnated copper alloy bushings in boom bases

Rigorous Quality Controls:

1. Material Certification: All incoming materials undergo spectrographic analysis

2. Precision Fabrication: CNC cutting and robotic welding for dimensional accuracy

3. Performance Validation:

   • 500-hour accelerated durability testing

   • 1.5x operational pressure hydraulic tests

4. Final Inspection: 37-point quality checklist before shipment

Continuous Improvement:

• Regular supplier audits for material consistency

• Real-world performance tracking from field operations

• ISO 9001-certified manufacturing processes

1. The long reach arm plate is precision-cut using a plasma cutting needle to ensure accuracy.

2. Before welding, the plate edges are milled (tapered) using a large edge milling machine. This allows for deep penetration of the weld into the steel plate, enhancing the overall performance of the structure.

3.After welding, a double-sided large-scale floor-standing boring machine is employed for precision boring. This ensures the long-reach arm concentricity during operation and extends its service life.

4. Environmentally friendly verified spraying room.
