803131669 XCMG GR2605 motor grader hose assembly

Core Product Advantages

Specifically designed and developed for the XCMG GR2605 motor grader, this hose is precisely matched to the model’s 194kW power output and the high-pressure operating conditions of the hydraulic system. It perfectly meets the wear-resistant, impact-resistant, and vibration-resistant requirements of harsh environments such as mines and infrastructure projects. Utilizing a double-layer high-density copper-plated steel wire braided reinforcement design, its pressure resistance is increased by 60% compared to ordinary hoses. With a rated working pressure of 35MPa and a 1.5 times safety margin, it effectively resists hydraulic system pressure pulses and impact loads, eliminating the risk of hose bulging and bursting. The inner rubber layer is made of special oil-resistant synthetic rubber, with a swelling rate of ≤3% after 72 hours of immersion at 70℃, enabling long-term resistance to corrosion from petroleum-based hydraulic oils. The outer rubber layer uses a UV-resistant and wear-resistant formula with a black textured surface, providing a service life of over 6 years in harsh outdoor environments, suitable for alternating high and low temperatures and complex terrain friction scenarios. The connector adopts an integrated cold-pressing molding process, with the metal sleeve and the hose tightly interlocking, and the sealing pressure reaches 1.5 times the working pressure, completely solving the slippage and leakage problems of traditional connection methods; the standardized interface strictly complies with the host installation specifications, can be quickly integrated without additional modification, is easy to maintain and has strong compatibility, and greatly reduces equipment downtime losses.

Application scenarios

Suitable for 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, frequent pipe bends, and severe vibration. 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. This effectively prevents system failures due to pipeline malfunctions, improves operational continuity and safety, and helps the machine maintain efficient and stable operation under complex and harsh working conditions.
