Product Description

The top-quality Caterpillar 312C excavator enjoys a high reputation in the construction machinery field for its outstanding performance and durability. This device is expected to have an operating time of over 5,000 hours, demonstrating its stability and reliability under various working conditions. It is equipped with Caterpillar's classic 3054 turbocharged engine, delivering a powerful output of up to 67 horsepower, ensuring that it can handle both flat excavation and complex terrain operations with ease. In terms of the hydraulic system, this machine is equipped with an efficient dual-pump system, which can achieve a precise and smooth operation experience. The main pump and the auxiliary pump work in coordination, which not only improves work efficiency but also ensures stability during long-term operation. In addition, the advanced hydraulic motor design makes the machine more adept at performing fine actions, enabling it to handle tasks such as excavation, loading, and crushing with ease. As a second-hand device, this Caterpillar 312C has been in excellent condition after professional maintenance and care, almost reaching the state of "playing freely at idle", which means it can maintain good operation even under low load.
