Nowadays, more global contractors and construction investors prefer purchasing second-hand XCMG machinery for its stable performance, affordable price and easy spare parts supply. However, many buyers worry about hidden faults, repainted appearance and false working hours when sourcing used construction equipment. Learning how to inspect the machine condition professionally can help you avoid risky deals and pick reliable used XCMG tower cranes, crawler cranes and other engineering machines with confidence.
First of all, start your inspection from the overall appearance, and distinguish original paint from repainted refurbishment. Genuine original XCMG equipment keeps uniform factory paint color, clear logo marks and natural slight wear without artificial polishing. Refurbished machines usually have obvious color difference at corners, boom and counterweight, with thick paint covering welding traces, collision damage or structural cracks. Heavy rust on key connections is also a warning sign of long-term poor maintenance. It is wise to avoid machines with large-area repainting and hidden structural repair records.
Secondly, focus on core components, especially the engine and hydraulic pump, which determine the service life of XCMG machinery. A qualified used XCMG engine starts quickly in cold condition, runs smoothly without abnormal knocking noise, and emits no continuous black, white or blue smoke. Check the engine oil and coolant to confirm no leakage or mixing. For the hydraulic system, inspect hydraulic pipes, cylinders and valve groups for oil seepage. Slow, jerky movement during operation means aging hydraulic pumps or faulty valve parts, which will cause high maintenance costs in later use.
Thirdly, judge the authenticity of working hours. Many suppliers modify the meter data to sell old machines at a high price. You can verify real working hours by combining tire wear, undercarriage abrasion, interior control panel aging and maintenance records. Low-hour XCMG equipment always shows uniform and slight overall wear, while high-hour modified machines have aging details inconsistent with the displayed meter data. Never judge the machine condition only by the digital hour meter.
Fourthly, master key test run points before final purchase. Start the equipment for no-load and simple load test, operate all functions including lifting, rotating and walking, and observe whether every action is sensitive and stable. Listen to the running sound carefully; abnormal vibration and harsh noise indicate internal component wear. Professional test run can expose hidden mechanical faults that cannot be seen from appearance inspection.
If you have no professional inspection experience, choosing a reliable supplier is the best choice. Our company strictly inspects all used XCMG tower cranes, crawler cranes and other construction machinery one by one, checking appearance, core parts, working hours and performing full test run before stock display. We only supply original condition, low-hour XCMG equipment without hidden faults and arbitrary refurbishment.
