XCMG XE2000 Excavator Support (Part No. 318307474): A Key Structural Support for Heavy-Duty Equipment

In the core structural system of large mining excavators, the support is the “load-bearing skeleton” that supports key components and distributes operational loads. XCMG’s specially developed support (part no. 318307474) for the XE2000 excavator, with its high-strength materials and optimized structural design, provides a solid guarantee for the stable operation of the equipment under heavy-duty conditions, offering a reliable structural support solution for engineering teams worldwide. High-Strength Alloy Base Material, Solid Load-Bearing Foundation

The XCMG XE2000 support (part no. 318307474) is integrally processed from low-alloy high-strength steel plate (Q690D). The steel plate thickness in the core stress area reaches 22mm. Authoritative testing shows that its base material has a tensile strength of 700MPa and a yield strength exceeding 680MPa, far exceeding the industry’s conventional support tensile standard of 550MPa. Through XCMG’s proprietary “overall tempering + local strengthening” heat treatment process, the support frame exhibits uniform overall mechanical properties, with key components achieving a hardness of HB280-320, making it less prone to plastic deformation during long-term heavy-duty operations.

Each support frame undergoes three rigorous tests: static load testing (withstanding 1.2 times the rated load without permanent deformation), dynamic fatigue testing (150,000 cycles of loading without cracking), and full dimensional accuracy inspection (flatness of key mounting surfaces ≤0.05mm/m). Actual test data shows that during 3500 hours of continuous heavy-duty operation testing, the structural deformation of this support frame was controlled within 0.18mm, extending its service life by 130% compared to ordinary support frames.

Optimized structural design enhances load-bearing efficiency

Targeting the heavy-duty operation characteristics of the XE2000 excavator, the support frame adopts a box-type structure design optimized by finite element analysis, reducing its weight by 18% while increasing overall rigidity by 35%. Reinforcing ribs are added to key load-bearing areas, reducing stress concentration by 30% and effectively dispersing impact loads during operation. The surface employs a three-layer anti-corrosion process: sandblasting + epoxy primer + wear-resistant topcoat, with a total coating thickness exceeding 110μm. It withstands 1000 hours of salt spray testing (equivalent to 5 years of outdoor corrosion protection), providing long-term resistance to rust in high-humidity, dusty mining environments.

The bracket mounting holes are precision-machined and honed, achieving an IT7 tolerance grade. Hole positioning accuracy is controlled within ±0.03mm, and the clearance with related components is ≤0.1mm. In extreme temperature tests ranging from -40℃ to 85℃, the bracket exhibits minimal thermal deformation, ensuring long-term precision and stability of all connections.

Adaptable to all working conditions, with superior stability

This support bracket is specifically designed for the multi-scenario operating needs of the XE2000 excavator, maintaining stable performance in extreme environments such as mines at altitudes of up to 5500 meters, mountainous work areas with a 30° slope, and muddy and wet swampy construction sites. Its bottom connection point with the machine body features an anti-slip and wear-resistant design, increasing the coefficient of friction by 40%, reducing the risk of displacement during operation, and minimizing the impact of vibration transmission on the machine body.

Actual engineering application data shows that XE2000 excavators equipped with this bracket experience a 70% reduction in structural component failure rate and an 85% reduction in downtime due to bracket issues. In heavy-duty excavation operations in large mines, the bracket effectively distributes more than 55% of the overall operating load, extending the fatigue life of related components by 70% and significantly improving the overall reliability of the equipment.

Original Factory Deep Compatibility, Enhanced System Efficiency

As a core structural component from XCMG, the 318307474 bracket achieves 100% precise matching with the hydraulic system, working device, and other key components of the XE2000 excavator, perfectly conforming to the overall machine’s structural stress design. The bracket has pre-reserved sensor mounting positions, allowing it to link with the excavator’s intelligent monitoring system to monitor vibration, stress, and other parameters in real time, providing early warning of potential faults.

The installation process uses original factory locating pins and high-strength bolts for fixation, requiring no on-site processing or adjustment. Installation accuracy reaches 0.02mm, improving installation efficiency by 60% compared to universal brackets. Data shows that XE2000 excavators equipped with original factory brackets experience a 30% improvement in overall structural stability and a 15% increase in action response accuracy during operation.

Choosing the XCMG XE2000 bracket (part number 318307474) means choosing structural safety guarantees verified under extreme working conditions, ensuring the heavy-duty excavator remains stable and reliable during high-intensity operations.
