380603570 XCMG GR2605 motor grader right door assembly

380603570 XCMG GR2605 motor grader right door assembly

The XCMG GR2605 grader 380603570 right door assembly is a core integrated component of the ROPS/FOPS certified luxury cab. It is manufactured in strict accordance with XCMG’s original design standards, GB/T 25684.8 grader safety requirements, ISO 3449 FOPS falling object protection and ISO 3471 ROPS rollover protection specifications. It is specially customized for the right-side driving safety and ease of operation of the GR2605 grader, and is perfectly adapted to extreme scenarios with high vibration, flying debris, dense dust and excessive noise, such as highway maintenance, airport runway construction, open-pit mine stripping, and large-scale earthwork filling. Serving as a “right-side safety barrier and convenient passage” for operators, this assembly integrates passive safety protection, sound insulation, unobstructed visibility, and flexible opening and closing. It effectively resists side impacts, falling objects, and dust intrusion, while reducing cab noise and temperature rise. It is a high-quality original factory replacement assembly for the GR2605 grader’s right door after issues such as sheet metal deformation, glass breakage, window regulator jamming, door lock failure, and air leakage, eliminating the need for piecemeal parts procurement and assembly.

This right door assembly utilizes a high-strength cage-type sheet metal frame structure. The core frame is made of Q355 high-strength low-alloy steel, precisely welded by robots and treated with overall electrophoretic rust prevention. The surface is then coated with a high-adhesion engineering machinery-specific topcoat, achieving a tensile strength ≥345MPa and excellent deformation resistance. The frame is filled with a high-density polyurethane sound and heat insulation foam layer, providing a sound insulation ≥25dB(A) and a thermal conductivity ≤0.03W/(m・K), effectively blocking construction noise and external high temperatures. Combined with the cab air conditioning system, it quickly creates a comfortable operating environment. The entire door has passed ROPS/FOPS dual protection tests, ensuring structural integrity in the event of a vehicle rollover or falling object impact, providing ample safety space for operators.

The core visibility component of the door features 5mm single-pane tempered safety glass (compatible with model 380603587 glass assembly standard), precision-cut by CNC and with rounded corners, eliminating stress concentration points. Its impact resistance meets GB 9656 standards, shattering into small, blunt-angled particles to prevent sharp scratches. The glass is equipped with a factory-installed dual-rail worm gear window regulator, using high-strength zinc alloy gears and cold-rolled steel guide rails for smooth, jam-free transmission. It supports both electric lifting (rated voltage 24V) and emergency manual lifting modes, with the lifting stroke precisely covering the door glass track, ensuring a seamless fit with the door frame when closed. The regulator motor has built-in overheat and anti-pinch protection, operating noise ≤45dB(A), and a service life ≥50,000 lifting cycles.

The door sealing system adopts a triple EPDM composite sealing structure: the outer side of the door frame is equipped with a dustproof and waterproof lip sealing strip, the middle is a skeleton-reinforced main sealing strip, and the inner side is a sound-insulating buffer strip. The three seals form a closed-loop protection with an IP67 protection level, which can completely block the intrusion of dust, mud, and rainwater, while absorbing the impact of door opening and closing and operational vibration. The door lock system is an original factory-dedicated heavy-duty engineering machinery rotary door lock, equipped with inner and outer double opening handles and an anti-accidental opening safety mechanism. After locking, it generates a locking force of ≥3000N, and will not loosen or open on its own under a peak vibration condition of 25g, effectively preventing the door from being accidentally opened during driving or operation. The door hinges are made of forged alloy steel, treated with high-frequency quenching, equipped with wear-resistant copper sleeves and lubricating grease, with an opening and closing angle of 90°, uniform opening and closing torque, and no loosening or abnormal noise after long-term use.

The door trim panels are made of flame-retardant ABS engineering plastic and knitted wear-resistant fabric, meeting the GB 8410 standard for flame-retardant automotive interior materials. The surface is treated with anti-fouling agents, making it easy to clean and scratch-resistant. The trim panels integrate door control modules, including window lift switches, door lock buttons, and work light control interfaces (compatible with 803506382 work lights). The layout is ergonomically designed, allowing operators to easily reach and operate the controls. The trim panels also include storage compartments and cup holders, balancing practicality and space utilization. The bottom of the doors is equipped with factory-installed drainage holes and dust valves to ensure rapid drainage of internal water and prevent corrosion.

The product’s hinge holes, door lock mounting positions, and wiring harness interfaces are all precisely matched 1:1 to the original XCMG GR2605 cab, with hole tolerances controlled within ±0.03mm. The wiring harness uses original factory standardized waterproof plugs, directly connecting to the cab’s main wiring harness without additional wiring modifications or adjustments. The assembly comes pre-installed with all core components (glass, regulators, door locks, sealing strips, interior panels), and can be fixed using 3 sets of high-strength hinge bolts and 1 set of door lock bolts. A single person with auxiliary tools can complete the entire disassembly and installation in 20 minutes. After installation, it perfectly fits the curved surface of the cab sheet metal, has a low drag coefficient, and eliminates whistling wind noise during high-speed operation.

This right door assembly has passed multiple authoritative tests and certifications: ISO 3449 FOPS falling object protection test, ISO 3471 ROPS rollover protection test, GB/T 25684.8 grader door safety standard, IP67 protection rating certification; 100,000-cycle door opening and closing fatigue test, with no loosening of hinges and no failure of door locks; 500-hour salt spray + UV aging test, with no rust on sheet metal and no hardening of sealing strips; wide temperature environment test from -40℃ to 80℃, with the window regulator and door lock operating normally.
