380603587 XCMG GR2605 motor grader glass assembly

The XCMG GR2605 grader 380603587 glass assembly is a core safety, visibility, and sealing component of the entire machine’s cab. Manufactured strictly according to XCMG’s original factory design standards, GB/T 44153 General Technical Requirements for Motor Vehicle Glass, and ROPS/FOPS Cab Protection Specifications, it is specifically designed for the GR2605 grader’s extra-large luxury cab. It is suitable for harsh working conditions such as highway construction, airport runway construction, open-pit mine stripping, and large-scale earthwork filling, characterized by high dust, flying debris, severe temperature differences, and strong ultraviolet radiation. Serving as a “visibility barrier and safety shield” for the operator, it combines clear light transmission, impact resistance, heat insulation, anti-glare, and sealing against dust and water. It effectively protects the safety of the driver and passengers and maintains a comfortable environment inside the cab. It is a high-quality original factory replacement part for GR2605 grader glass that has cracked, broken, or leaked due to aging seals.

This glass assembly adopts a laminated tempered composite structure. The outer layer is 5mm tempered glass, and the inner layer is a composite process of 3mm safety interlayer film + 4mm tempered glass. Upon impact, it does not produce sharp, flying fragments. Even if it breaks, the interlayer film maintains the overall integrity, preventing cuts. The glass surface is treated with a nano-level anti-glare and anti-UV coating, with an UV blocking rate of ≥99%, a total solar transmittance of ≤45%, and a light transmittance stable in the range of 78%-82%. This avoids visual fatigue and glare caused by direct sunlight and effectively reduces the temperature rise in the driver’s cabin during summer, improving air conditioning efficiency. The edges are precision-cut by CNC and rounded, eliminating stress concentration points and significantly improving wind pressure and vibration resistance compared to ordinary glass.

The glass assembly is equipped with a custom-made EPDM (ethylene propylene diene monomer) integrally molded sealing strip, which precisely fits the curved surface of the cab sheet metal with a gap of ≤0.05mm. It achieves an IP65 protection rating, completely preventing dust intrusion and low-pressure water jet spray, effectively isolating rainwater, mud, and construction dust from entering the cab. It also provides excellent sound insulation and noise reduction, reducing external operating noise by 18-22 decibels. The strip has an internal metal frame for enhanced rigidity, ensuring it will not detach, loosen, or make abnormal noises under 25g peak vibration conditions after installation. Furthermore, it has a temperature resistance range of -40℃ to 80℃, and will not age, harden, or crack during long-term outdoor use.

The product’s mounting holes, clip slots, and curved surfaces are precisely matched 1:1 to the pre-drilled positions in the original XCMG GR2605 cab. Hole tolerances are controlled within ±0.03mm, and curved surface fit errors are ≤0.1mm, requiring no additional cutting, drilling, or modification. Installation utilizes a dual fixing method of original factory-specific polyurethane structural adhesive and clips, ensuring fast curing, high bonding strength, and easy individual disassembly and replacement without requiring complete cab frame disassembly, significantly improving maintenance efficiency. The overall appearance maintains a high degree of consistency with the original cab style, without affecting the machine’s sealing performance or aesthetic integrity.

The glass assembly has passed the national mandatory certification for motor vehicle safety glass (CCC certification) and meets the ISO 3537 standard for impact performance of laminated glass. The coating adhesion has passed a 1000-hour salt spray + UV aging test with no peeling or yellowing, ensuring long-term stable use in extreme environments such as coastal salt spray and high-altitude ultraviolet radiation. The matching sealing system has passed a 100,000-cycle vibration fatigue test with no leakage or abnormal wear.
