【 Premium Recommendation 】 The top-quality original Caterpillar 307E2 excavator is a rare and excellent choice in the second-hand market. Since leaving the factory, the cumulative working time has only been around 3,500 hours. For such a high-quality construction machinery, this usage time is almost negligible, indicating that it is still in the best condition. In terms of power, this aircraft is equipped with a C1.6 turbocharged diesel engine produced by Caterpillar itself, with a maximum output power of up to 40.4 kilowatts (approximately 54 horsepower), ensuring strong power while also taking into account fuel economy. After professional testing, the entire power system operates smoothly without any abnormal noise or oil leakage. It can be said that the "three major components" - the engine, transmission and main pump - are all kept very dry and have never undergone unnecessary disassembly or maintenance. Their original performance has been retained to the greatest extent. In terms of the hydraulic system, the 307E2 model adopts advanced load sensing technology, which can automatically adjust the flow distribution according to the actual operation requirements, thereby achieving an efficient and energy-saving operation experience.2025-12-10 14:59:58
