803171944 XCMG GR2605 motor grader hose assembly

Core Product Advantages

Specifically designed and developed for the XCMG GR2605 motor grader, this hose perfectly matches the model’s 194kW power output and the high-pressure requirements of its hydraulic system. It is suitable for harsh working environments such as mining and infrastructure projects, demanding high wear resistance and impact resistance. Featuring a double-layer high-density steel wire braided reinforcement design, its pressure resistance is over 50% higher than ordinary hoses, capable of withstanding working pressures up to 40MPa. This effectively resists hydraulic system pressure shocks and pulse loads, eliminating the risk of hose bursting. The inner rubber layer uses imported oil-resistant synthetic rubber, with a swelling rate of ≤5% after 72 hours of immersion at 70℃, providing long-term resistance to hydraulic oil corrosion. The outer rubber layer incorporates UV-resistant and wear-resistant formulas, ensuring an outdoor service life of over 5 years, suitable for alternating high and low temperatures and complex terrain friction scenarios. The connector is processed using a cold-pressing process, ensuring a tight fit between the metal and the hose, with a sealing pressure 1.5 times the working pressure, completely eliminating slippage and leakage. The standardized interface design conforms to the main unit’s installation specifications, allowing for quick integration without additional modifications, convenient maintenance, and strong compatibility.

Application Scenarios

Suitable for XCMG GR2605 graders in soil leveling, slope trimming, and heavy-duty operations in mining, road construction, and farmland improvement projects, especially suitable for harsh working conditions with high-frequency oscillation and frequent pipeline bends. As the “power artery” of the hydraulic system, it provides stable and leak-free power transmission to key hydraulic components such as the grader’s blade drive, steering system, and braking circuit, effectively reducing equipment downtime losses due to pipeline failures, improving operational continuity and safety, and helping the machine maintain efficient operation under complex conditions.
