In today’s construction equipment market, used excavators are becoming increasingly popular due to their excellent balance of cost and performance. Among them, the Komatsu PC270-7 stands out as a reliable medium-to-large excavator widely used in mining, road construction, and major infrastructure projects. However, buying a used construction equipment always carries certain risks. To avoid costly mistakes, here are five key points you should carefully consider before purchasing a used Komatsu PC270-7.
1. Inspect the Engine and Hydraulic System
The engine is the “heart” of any excavator, while the hydraulic system acts as its “circulatory system.” When buying second-hand equipment, you must check if the engine starts smoothly, and whether there are signs of black smoke, oil leaks, or unusual vibrations. Similarly, the hydraulic system should operate steadily without strange noises or sluggish movements. Issues in these areas often mean high repair costs later on.
2. Check the Operating Hours
Operating hours are a key indicator of how much life an excavator has left. While the PC270-7 is designed for long service life, machines with over 10,000 hours of work demand extra caution. That said, numbers alone don’t tell the whole story—some machines with higher hours remain reliable if well-maintained, while poorly maintained units may have problems even at lower hours.
3. Examine the Undercarriage and Structural Components
As a tracked excavator, the condition of the undercarriage directly affects performance and stability. Pay attention to the track chains, rollers, and drive sprockets for signs of excessive wear. Also, carefully inspect the boom, arm, and bucket for cracks, bends, or heavy repair marks. These may indicate that the machine has undergone heavy or even overloaded work in the past.
4. Review Maintenance and Service Records
A well-maintained machine is always more reliable than one without proper care. Ask the seller for detailed maintenance history, including oil changes, filter replacements, hydraulic system services, and any major repairs. A clear record not only provides confidence in the machine’s condition but also helps estimate future maintenance needs.
5. Consider Price and After-Sales Support
Price is naturally an important factor, but it should not be the only one. The market price for a used Komatsu PC270-7 excavators varies depending on the year, condition, and hours. In addition, availability of parts and reliable service is crucial. Fortunately, Komatsu has a strong global service network, making it easier to find replacement parts and qualified technicians—an advantage that gives buyers more peace of mind.
Conclusion
Buying an original used Komatsu PC270-7 excavator is not just about finding the lowest price—it’s about making a smart investment. By paying close attention to the engine and hydraulic system, operating hours, undercarriage condition, maintenance records, and after-sales support, you can significantly reduce risks and secure a machine that offers great value. With the right approach, a second-hand PC270-7 can deliver reliable performance and strong support for your construction projects.
