Komatsu PC400 Guard Plate 208-30-61190

As a dedicated idler wheel protection component for Komatsu PC400 heavy-duty excavators, the Komatsu PC400 excavator support wheel guard plate adopts a heavy-duty structural design, perfectly suited to the high-load, high-intensity operating characteristics of the equipment. In harsh construction environments like mines and infrastructure sites, this guard plate delivers robust protection to the idler wheel system-effectively reducing idler wheel malfunctions associated with the Komatsu PC400 excavator support wheel guard plate, ensuring the equipment operates continuously and stably, and ultimately boosting construction efficiency.

For materials, the Komatsu PC400 excavator support wheel guard plate exclusively uses Q345B high-strength structural steel, a material renowned for exceptional comprehensive mechanical properties, including high tensile strength and excellent toughness. It easily withstands severe vibrations and impacts during heavy excavator operation, laying a stable material foundation for the guard plate. The raw material procurement process follows strict quality control standards: each batch comes with a material certificate and undergoes rigorous sampling inspections upon arrival, covering chemical composition analysis, tensile tests, and impact tests. This ensures material properties meet design requirements, securing product reliability from the source.

The manufacturing stage combines high-precision equipment with standardized procedures to craft superior quality. Single-piece cutting relies on laser technology, achieving high-precision, high-efficiency results that keep part dimensional errors within an extremely narrow range. CNC bending machines, equipped with precise control systems, handle the forming of the guard plate's complex curved surfaces and folded edges-guaranteeing a tight fit between the product, the PC400 excavator's support wheel system, and the Komatsu PC400 excavator support wheel guard plate itself. During assembly, single-piece and overall assembly jigs work in tandem to ensure each component is accurately positioned and tightly fitted, enhancing structural stability and load-bearing capacity.

Welding operations utilize automated welding robots paired with specialized welding positioners, creating uniform, full weld seams while effectively avoiding defects like pores and slag inclusions-ensuring weld strength meets heavy-duty operation demands. Subsequent processing via CNC machining centers and boring machines ensures installation hole precision and connection surface flatness, enabling quick, accurate installation. Surface treatment employs a "primer + topcoat" double-spray process: the primer offers strong rust resistance, while the topcoat is a specialized coating with high wear resistance and anti-aging properties. This combination resists oil stains, sand abrasion, and harsh weather erosion in construction sites, significantly extending the product's weather resistance and service life.
