803274959 XCMG GR2605 motor grader hose assembly

Core Product Advantages

Specifically designed and developed for the XCMG GR2605 motor grader, this product precisely matches the model’s 194kW power output and the high-pressure operating conditions of the hydraulic system. It is perfectly suited for harsh environments such as mines and construction sites, characterized by dust, intense vibration, and flammable/explosive materials. Utilizing a multi-layered, high-density galvanized steel wire winding reinforcement design, its pressure resistance is improved by 90% compared to traditional braided structures. It has a rated working pressure of 42MPa, with a 1.5 times safety margin. It has passed the ISO6803 standard 500,000-cycle pulse 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 ≤1.8%, allowing for long-term resistance to corrosion from various media such as petroleum-based hydraulic oil, mineral oil-based hydraulic media, and water-oil emulsions. 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 possesses ozone resistance, wear resistance, and UV resistance, ensuring a service life of over 9 years in harsh outdoor environments. It is suitable for alternating high and low temperatures (-40℃~120℃) and complex terrain friction scenarios. The connector uses an integrated cold-pressing molding 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, allowing for quick integration without additional modifications. It is convenient to maintain and highly compatible, significantly reducing equipment downtime losses and meeting the high reliability and mining safety standards of XCMG hydraulic components.

Application scenarios

Suitable for XCMG GR2605 Graders are used in various applications such as soil leveling, slope trimming, and heavy-duty operations in mining, underground operations, open-pit mines, and road construction. They are particularly well-suited for the harsh working conditions of mining, including high-frequency oscillation, frequent pipe bends, severe vibrations, and flammable and explosive environments. As the “safe 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. Simultaneously, its flame-retardant and anti-static properties eliminate safety hazards in mining environments, effectively preventing system paralysis and safety accidents caused by pipe failures. This significantly improves operational continuity and safety, helping the machine maintain efficient and stable operation in complex and harsh mining environments. It is an original equipment manufacturer (OEM) safety adapter for the hydraulic system repair and replacement of the XCMG GR2605 grader.
