Product Description

Second-hand Caterpillar 312C excavator, Long Arm version This is a second-hand Caterpillar 312C excavator with outstanding performance and good condition, specially equipped with a 16-meter extended arm, suitable for deep digging operations in various complex working conditions. The cumulative working time of this machine is only 4,500 hours, which is of medium usage intensity. The overall mechanical condition remains good, and the wear degree of each component is relatively low, making it have a relatively long service life. In terms of power, this machine is equipped with an original imported C4.4 diesel engine from Caterpillar, with a rated power of 75kW (approximately 100 horsepower). While ensuring strong power output, it also features excellent fuel economy, effectively reducing operating costs. In addition, the advanced electronic fuel injection technology makes the engine run more smoothly and reliably, with low noise and emissions meeting environmental protection standards. The hydraulic system adopts Caterpillar's patented positive flow control technology, ensuring smooth and continuous operation of the entire machine, as well as rapid and sensitive response. This performance is particularly outstanding during meticulous e
