【 Premium Recommendation 】 A second-hand Caterpillar 305.5E excavator manufactured in November 2017 is in excellent condition, so there's no need to worry about any mechanical issues. This equipment has maintained a good maintenance record since it left the factory, with a cumulative working time of only 3,500 hours, which is far lower than the average service life of the same model. This means that it still has a long service life to be explored. In terms of the power system, this aircraft is equipped with Caterpillar's self-developed C1.7 inline four-cylinder turbocharged diesel engine, with a maximum output power of up to 24.6 kilowatts (approximately 33 horsepower). It ensures strong performance while also taking into account fuel economy, enabling it to easily handle various challenges whether on urban construction sites or in outdoor operations. The hydraulic system adopts advanced load sensing technology, which can automatically adjust the oil supply according to the actual operation requirements, ensuring smooth and stable operation as well as rapid response. In addition, it is equipped with an efficient cooling device, which can maintain a stable working state even after long-term high-intensity operation. This product is f2025-12-05 12:18:46
