2020 second-hand Doosan 225 excavator excellent condition and suitable for countries in Latin America

Equipped with the original Korean Doosan engine, it has strong and abundant power, capable of handling various working scenarios and improving work efficiency. In some large earthwork projects, mining operations, and other situations, it can efficiently complete excavation, loading, and other tasks. With the new hydraulic system, its movements are smooth and stable, providing excellent control and operation performance, reducing vibration and shaking during the movement of the excavator, and improving work stability. During excavation, rotation, etc., the equipment can maintain stable operation. With the original Doosan efficient engine, its fuel economy is excellent, reducing fuel consumption, saving energy costs, and lowering operating costs. Through the use of high-quality materials and strict production processes, the reliability and durability of the product are ensured, reducing the failure rate, extending the service life of the excavator, and reducing the frequency of maintenance and equipment replacement. 

To ensure that our product quality can meet the expectations of customers, we will conduct detailed inspections on each excavator to ensure it is in good working condition. Inspection items and requirements are as follows:

Appearance and structure inspection requirements: Check if the boom and boom frame have welding defects or cracks (this is a sign of refurbishment);

Engine system inspection requirements: The engine exhaust should be normal, without abnormal noise, no blue smoke, no carbon deposits in the exhaust pipe, no oil leakage in the oil pan, no noise at idle speed.

Requirements for hydraulic system inspection: The hydraulic pump/motor should show no vibration, no cracks, and no oil leakage. The pressure should be stable. The chrome coating of the cylinder should have no scratches or oil leakage. The operation should be smooth. The pipeline should be confirmed to have no bulges or aging phenomena.

Requirements for electrical system inspection: The computer board should be able to display speed, pressure and fault codes normally. Wiring connection: The lighting, air conditioning and alarm systems should be able to operate normally.

Requirements for transportation system inspection: Track: The rubber layer should have no cracks, the chain guide rail should have slight wear, and the number of chains should match the machine. Motor: The rotational speed on both sides should be consistent during transportation, and the transportation should be normal.

Requirements for cooling and intake system inspection: The radiator should remain clean and free of dust, and the fan belt should not be loose. The list of easily damaged parts that must be replaced before mechanical transportation: Replace new engine oil, hydraulic oil and gear oil; replace new air filter, oil filter and diesel filter; replace intake/exhaust/pilot/pipeline filter elements; other damaged parts will also be replaced with new ones.
