How does Yuezhong Construction Machinery's wear-resistant components achieve "30% longer equipment lifespan"?

I. Bucket Teeth: Material Adaptation Superior to Blindly "Stacking Materials"

Traditional bucket teeth often use single high-manganese steel, which, despite its considerable thickness, is prone to cracking due to insufficient toughness. After thousands of tests under various working conditions, Yuezhong discovered that the wear resistance of bucket teeth depends on the "balance between toughness and hardness." Therefore, they developed a "high-manganese steel matrix + chromium carbide composite layer" structure: the high-manganese steel ensures impact resistance and toughness, while the surface chromium carbide composite layer achieves a hardness of HRC60 or higher, far exceeding the HRC45 of traditional high-manganese steel. Actual tests show that the lifespan of traditional bucket teeth is approximately 35 days, while Yuezhong's composite bucket teeth can reach 72 days, doubling the wear resistance lifespan and achieving a qualitative improvement in the performance of engineering machinery bucket teeth.

II. Wear-Resistant Plates: On-Demand Adaptation Balancing Lifespan and Cost

Previously, the industry often used "all-thickness universal" wear-resistant plates, which, while seemingly safe, increased equipment weight, fuel consumption, and wasted resources. Yuezhong, through three-dimensional stress simulation, discovered that 80% of the bucket load is concentrated in the bottom and cutting edge areas, while the load in non-stress areas is only 1/5. Based on this, a "zonal adaptation" solution was developed: 20mm thick NM450 wear-resistant plates are used in the core stress area to ensure performance, while 12mm thick NM360 plates are used in non-stress areas to achieve weight reduction. In actual tests, loader buckets using this solution showed a 120kg reduction in weight per unit, a 4.2L reduction in fuel consumption per 100km, and annual fuel cost savings of approximately 18,000 yuan. Simultaneously, bucket lifespan was increased by 15%, achieving a win-win situation in terms of both lifespan and cost.

III. Main Cutting Plate: Installation Accuracy Determines Half of Durability

After-sales surveys show that 50% of early damage to the main cutting plate stems from uneven wear caused by installation errors—traditional installation relies on manual alignment, with errors reaching 2-3mm, and local wear rates three times faster than normal. Yuezhong optimized the design: pre-reserved "positioning holes + buffer grooves," combined with specialized tooling, to control installation errors within 0.5mm, ensuring a perfect fit; the buffer grooves absorb impact to prevent misalignment, supplemented by installation guidance services to ensure successful installation. In open-pit coal mine tests, Yuezhong's main cutting plate lifespan increased from 45 days to 120 days, and the uneven wear failure rate decreased to 3%, effectively eliminating the problem of early damage to wear-resistant components in construction machinery.

Conclusion: Technological Innovation Forges Core Competitiveness

Yuezhong's 17 years of practice have proven that extending the lifespan of wear-resistant components in construction machinery requires systematic optimization of materials, design, and processes. From composite bucket teeth to zoned wear-resistant plates, and then to high-precision main cutting plates, every innovation stems from insightful understanding of operating conditions. As a leading enterprise's supporting service provider, Yuezhong consistently aims to "extend lifespan and reduce costs."
