XCMG XE2000 Excavator Hoses (Part No. 804414126): Flexible Power Channel for High-Pressure Hydraulic Systems

In the high-pressure hydraulic systems of large mining excavators, hose assemblies are key components connecting fixed pipelines to moving parts, enabling flexible transmission of hydraulic oil. XCMG’s specially developed hose assembly (part no. 804414126) for the XE2000 excavator, with its high-strength composite materials and precision manufacturing process, serves as the “power blood vessel” for the flexible operation of the hydraulic system in heavy-duty operations, providing a safe and durable flexible connection solution for engineering teams worldwide.

High-Strength Composite Materials: A Foundation for Pressure Resistance and Flexible Operation

The XCMG XE2000 hose assembly (part no. 804414126) adopts a multi-layer composite structure design. The inner tube is made of high-pressure and oil-resistant nitrile rubber, the reinforcing layer is a high-strength steel wire braided layer (4 layers of cross braiding), and the outer sheath is made of wear-resistant neoprene rubber. Authoritative testing shows that this hose assembly has a rated working pressure of 40MPa and a burst pressure exceeding 120MPa, representing a 50% improvement in pressure resistance compared to conventional hose assemblies in the industry.

Through XCMG’s proprietary “layered vulcanization + precision crimping” process, the connection strength between the hose and the connector reaches 18kN, eliminating the risk of detachment under high-frequency bending and high-pressure impact. Each assembly undergoes five rigorous tests: a 50MPa water pressure test (no leakage after 30 minutes of pressure holding), a pulse fatigue test (no cracks after 200,000 pressure cycles), a bending radius test (minimum bending radius up to 4 times the nominal diameter), a wear resistance test (wear ≤0.1mm/1000 friction cycles), and a temperature resistance test (stable performance from -40℃ to 120℃). Actual test data shows that after 3000 hours of continuous heavy-duty operation, the performance degradation rate of this assembly is less than 5%, and its service life is 200% longer than that of ordinary hose assemblies.

Precision structural design ensures efficient and flexible power transmission

Addressing the complex motion trajectories of the XE2000 excavator, the hose assembly features an optimized length and bending angle design. The optimal layout was determined using 3D motion simulation technology, ensuring no excessive stretching or twisting during the full stroke of the excavator’s boom and stick. The inner tube wall undergoes an ultra-smooth treatment (roughness Ra0.8μm), reducing hydraulic oil flow resistance by 20%. Combined with a streamlined connector design, this achieves efficient hydraulic power transmission.

The assembly connector is precision-machined from forged steel, and the crimping area employs a stepped structure design to ensure uniform pressure distribution and prevent premature damage caused by localized stress concentration. The outer sheath surface features an anti-slip and wear-resistant texture design, improving wear resistance by 30% while also possessing excellent ozone and UV resistance, preventing cracking even after long-term outdoor use. Actual testing shows that the dynamic pressure loss rate of this hose assembly is less than 3%, and the hydraulic response speed is 15% faster than traditional hoses under full load operation.

Adaptable to extreme environments with no performance degradation

This hose assembly is specifically designed for the multi-scenario operational needs of the XE2000 excavator, maintaining stable performance in extreme environments such as high-altitude mines at 5000 meters, extremely cold regions at -40°C, deserts at 50°C, and high-humidity coastal construction sites. The inner tube rubber uses a special low-temperature resistant formula, maintaining good flexibility even at -40°C without the risk of hardening and cracking; the outer sheath is enriched with anti-aging additives, extending its service life to twice that of ordinary hoses under strong ultraviolet radiation.

Actual engineering application data shows that XE2000 excavators equipped with this assembly experience a 90% reduction in hydraulic hose failure rate and a 95% reduction in hydraulic oil leakage due to hose rupture. In dusty quarry operations, the outer sheath effectively resists sand and gravel impacts; in wet and muddy construction sites, the assembly shows no corrosion or rust; in continuous vibration crushing operations, there is no loosening or leakage at the joints, ensuring reliable operation of the hydraulic system in various harsh environments.

Original Factory Deep Compatibility, Enhanced System Efficiency

As a core original hydraulic component from XCMG, the 804414126 hose assembly achieves 100% precise matching with the hydraulic system parameters and motion trajectory of the XE2000 excavator, perfectly aligning with the machine’s hydraulic flow requirements and layout design. The assembly length error is controlled within ±5mm, ensuring perfect fit with related components and avoiding additional stress caused by dimensional deviations.

The installation process adopts a “plug-and-play” design, equipped with original factory positioning marks and dedicated installation tools, improving installation efficiency by 60% compared to traditional hoses. Data shows that using the original factory hose assembly can reduce energy loss in the XE2000 excavator’s hydraulic system by 10%, improve the response speed of moving parts by 12%, and increase the overall operating efficiency of the equipment by 8%. Choosing XCMG XE2000 genuine hose assembly (part number 804414126) means selecting a flexible power guarantee for your heavy equipment, proven under extreme working conditions. This ensures that the high-pressure hydraulic system maintains efficient, safe, and durable operation during high-intensity work, creating greater economic benefits and equipment reliability for your project.
