803420506 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 the high-pressure operating conditions of the hydraulic system. It precisely meets the needs of harsh environments such as mines and construction sites, characterized by dust, intense vibration, and flammable/explosive materials. Utilizing a six-layer high-density galvanized steel wire winding reinforcement design, its pressure resistance is improved by 40% compared to the traditional four-layer structure. The rated working pressure reaches 38MPa, 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 600,000 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 ≤1.5%, 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 10 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 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. 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 XCMG GR2605 graders in soil leveling, slope trimming, and heavy-duty operations in mining, underground operations, open-pit mines, road construction, and other projects. Especially suitable for harsh mining conditions characterized by high-frequency oscillation, frequent pipeline bends, severe vibration, and flammable and explosive environments. As the “safe power blood vessel” of the hydraulic system, its six-layer steel wire winding structure and efficient sealing design provide stable and leak-free power transmission for 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 pipeline failures. It significantly improves operational continuity and safety, helping the machine maintain efficient and stable operation in complex and harsh mining environments. It is an original factory-grade safety adapter part for the maintenance and replacement of the XCMG GR2605 grader hydraulic system.
