Komatsu PC200 Guard Plate 20Y-30-31160

The Komatsu PC200 excavator support wheel guard plate is custom-engineered for Komatsu PC200 excavators, serving as a critical protective component to ensure stable operation of the equipment's support wheel system. As a key part that integrates seamlessly with the excavator's travel mechanism, its precise dimensional specifications and reliable structural performance effectively ward off flying sand, gravel, and debris during construction. This prevents jamming and abrasion of the idler wheels, significantly extending the idler's service life while reducing equipment maintenance costs.

Crafted from high-strength Q345B steel plate, the guard plate boasts exceptional impact resistance, fatigue durability, and weldability-ideal for the harsh, variable working conditions excavators face. All raw materials undergo strict incoming inspection, including spectral analysis and mechanical property testing, to verify compliance with material composition and performance standards. This rigorous quality control lays a solid foundation for product reliability right from the source.

High-precision process control governs every stage of manufacturing the Komatsu PC200 excavator support wheel guard plate. For single-piece cutting, laser technology is employed to achieve a cutting accuracy of ±0.1mm, ensuring consistent part dimensions. CNC bending machines handle the forming process, creating precise curves that ensure a perfect fit with the support wheels. Dedicated single-piece and integral assembly jigs are used during assembly to tightly control component clearances and enhance structural stability. Welding is performed by robotic systems paired with positioners, producing uniform, full welds that far exceed manual welding strength and eliminate common welding defects. Subsequent precision machining via CNC machining centers and boring machines guarantees accurate mounting holes and connection surfaces, enabling quick and easy installation. Surface treatment involves a two-coat painting process-primer for enhanced adhesion and rust resistance, plus a wear-resistant, anti-aging topcoat that resists rain and oil corrosion, boosting the product's weatherability.
