Since its establishment, Shandong Xiaowang Construction Machinery has focused on R&D and manufacturing of core structural components for Komatsu excavators. Over its two decades of development, the company has stuck to a core goal: "matching Komatsu models and ensuring efficient equipment operation." From raw material selection to production process optimization, and from finished product inspection to after-sales service, it has built a standardized system covering the entire process.
Today, the company has modern production workshops, precision CNC machining equipment, and professional testing instruments. It also has a technical team well-versed in Komatsu excavator structures-one that can respond quickly to customer needs. This ensures every product fits Komatsu models precisely, meeting the protection requirements for long-term, high-intensity equipment operation.
Core Products
Designed for mainstream Komatsu models, the company's key offerings are support wheel guards and chain guards for Komatsu excavators. These parts are critical protective components for the excavators' travel and chassis systems: they effectively block impurities like sand and gravel from entering, reduce wear on idlers and chains, extend equipment service life, and lower maintenance costs. Currently, the products cover all of Komatsu's mainstream models, with key compatible lines as follows:
PC200 Series:
Tailored to the chassis structure of Komatsu PC200 excavators. The guard's curvature fits the machine body perfectly, and its mounting holes align precisely-this tightly wraps the idlers to prevent impurity buildup during operation. The chain guard uses high-strength alloy, offering strong impact resistance to stop chains from shifting or falling off.
01
PC210/PC220 Series:
These models often work in high-dust, high-impact environments (e.g., mines, infrastructure sites). To adapt, the product's guard thickness is increased to 28mm, and the chain guard surface gets a wear-resistant coating. This boosts wear resistance by over 30% compared to standard accessories, making it suitable for long-term high-intensity use.
02
PC240/PC270 Series:
Built for the model's fast travel speed and heavy load. The support wheel guard's load-bearing structure is optimized with a "double-layer reinforcing rib" design to disperse operational impact. The gap between the chain guard and chain is controlled at 0.5–1mm, ensuring smooth chain movement while reducing noise and wear.
03
PC300/PC360 Series:
As Komatsu's core medium-to-large excavators, these demand highly durable components. The company's customized support wheel guards use Q345 high-strength wear-resistant steel and are formed via integral stamping-no weak weld points.
04
PC400 Series:
Designed for large-scale mining operations. Protective performance is further upgraded: guard edges are reinforced with folded edges, and chain guards include "anti-break limit blocks." These address chain stability issues under heavy loads and rough conditions, keeping equipment running normally even in extreme work environments.
05
Core Advantages
Beyond compatibility, the company's support wheel guards and chain guards for Komatsu excavators offer three key strengths:
Durable Materials:
Every part uses high-strength steel and alloys that meet construction machinery standards. They undergo quenching and tempering, plus anti-rust surface treatment-delivering excellent corrosion resistance and fatigue strength. This lets them stand up to harsh conditions like high temperatures, high humidity, and heavy dust.
Precise Fit:
Leveraging over 20 years of technical expertise with Komatsu models, part size tolerance is kept within ±0.3mm. No secondary modifications are needed during installation, saving time and effort.
Great Value for Money:
In-house production cuts out middlemen costs, so pricing is more competitive than OEM parts. The company also offers a 12-month warranty-if any quality issues arise during this period, we provide free replacements. This lets customers buy with confidence and use at ease.
