803373252 XCMG GR2605 motor grader hose assembly

Core Product Advantages

Specifically designed and developed for the XCMG GR2605 motor grader, this product perfectly matches the model’s 194kW rated power output and load-sensing hydraulic system operating conditions. It precisely meets the stringent operational requirements of dusty, high-vibration, and high-frequency start-stop operations in mining, highway construction, and infrastructure projects. Utilizing a three-layer high-density galvanized steel wire braided reinforcement design, its pressure resistance is improved by 25% compared to traditional double-layer structures. The rated working pressure reaches 32MPa, with a 1.5 times safety margin (compatible with the main unit’s maximum working pressure of 24.5MPa). It has passed the ISO 18752 dynamic pressure standard 450,000 pulse cycle test without leakage, effectively resisting high-frequency pressure impacts and pulse loads in the hydraulic system, eliminating the risk of pipe bulging and bursting. The inner rubber layer is made of oil-resistant and anti-aging special synthetic rubber. After immersion at 70℃ for 72 hours, the swelling rate is ≤2.2%, allowing for long-term resistance to corrosion from various media such as petroleum-based hydraulic oil, mineral oil-based hydraulic media, and water-glycol. The outer rubber layer uses a flame-retardant and anti-static formula with a surface resistance ≤3×10^8Ω, meeting mining explosion-proof safety requirements. It also incorporates a wear-resistant coating and UV-resistant components, ensuring a service life of over 7 years in harsh outdoor environments. It is suitable for alternating high and low temperatures (-30℃~105℃) and complex terrain friction scenarios. The connector uses an integrated cold-pressing process, with a tight fit between the metal sleeve and the hose, achieving a sealing pressure 1.5 times the working pressure, completely solving the slippage and leakage problems of traditional connection methods. The standardized interface strictly complies with XCMG’s original factory installation specifications, supporting 0°/45°/90° multi-angle assembly, adapting to the compact piping layout of the entire machine. It can be quickly integrated without additional modifications, offering convenient maintenance and strong compatibility, significantly reducing equipment downtime losses, and meeting the high reliability and mining safety standards of XCMG hydraulic components.

Application scenarios

Suitable for soil leveling, slope trimming, and heavy-load road surface operations in mining, highway construction, infrastructure construction, farmland improvement, and other projects. Especially suitable for harsh working conditions in mining, such as high-frequency oscillation, frequent pipeline bends, severe vibration, and flammable and explosive environments. As the “safe power blood vessel” of the hydraulic system, its three-layer steel wire braided structure and efficient sealing design perfectly match the host load-sensing hydraulic system, providing stable and leak-free power transmission for key hydraulic components such as the grader’s blade drive, steering system, and braking circuit. At the same time, its flame-retardant and anti-static properties eliminate safety hazards in mining environments, effectively preventing system paralysis and safety accidents caused by pipeline failures. It significantly improves operational continuity and safety, helping the machine maintain efficient and stable operation under complex and harsh working conditions. It is an original factory-grade safety adapter part for the maintenance and replacement of the XCMG GR2605 grader hydraulic system.
