This Caterpillar 312D2GC excavator was purchased in 2015 and has undergone several years of testing. However, its performance remains outstanding and it is a high-quality second-hand construction machinery rarely seen in the market. This equipment is specially designed for earthwork operations, with a cumulative working time of approximately 4,000 hours. It is in good condition and is highly suitable for engineering projects that require efficient completion of earthwork excavation tasks. In terms of power, this 312D2GC is equipped with a powerful and reliable engine, which can provide sufficient power output and ensure stable operation under various complex working conditions. After professional testing, its power system performs exceptionally well. Both the starting speed and fuel economy are satisfactory, almost reaching the "no-inspection" level. As one of the core components of an excavator, the hydraulic system has also received sufficient attention and optimization on this machine. By adopting advanced hydraulic technology, not only has the work efficiency been improved, but also the flexibility and smoothness of operation have been enhanced, enabling the driver to control the equipment more easily to complete precise tasks.
