Used Caterpillar CAT315D2GC Excavator

Under the hood, the 315D2GC is powered by the CAT C4.4 ACERT engine, delivering approximately 97.9 kW (132.9 HP) of net power with a maximum torque of 637 N·m. What sets this engine apart is its direct injection design, which offers significantly better tolerance to lower-quality diesel fuels commonly found on domestic job sites compared to electronic injection systems.

The fuel economy is where this machine truly shines. In standard earthmoving operations, actual fuel consumption runs at just 8–11 liters per hour—10% to 15% lower than comparable joint-venture models in the same weight class. The engine supports three power modes (High Power / Standard / Economy), allowing operators to tailor performance to specific tasks—whether it’s bulk excavation, hard digging, or demolition work.

The 315D2GC employs Caterpillar’s classic negative flow control technology, delivering smooth and coordinated compound movements. Operations such as material swinging, truck loading, and grading are fluid and jerk-free, making the machine exceptionally easy for operators to learn and master. The pilot control requires minimal effort, significantly reducing operator fatigue during extended shifts.

The hydraulic system delivers a maximum flow of 2 × 132 liters per minute, providing ample power for demanding applications. All hydraulic lines and seals use Caterpillar’s original high-specification components, resulting in low oil leakage rates. With proper maintenance, the hydraulic system’s service life can exceed 15,000 hours.

Caterpillar built the 315D2GC with reinforced booms, arms, and upper and lower frames. The hinge points feature integral cast structures that effectively distribute stress, minimizing the risk of cracking during prolonged heavy use. The tracks, track rollers, and carrier rollers have all undergone wear-resistant thickening treatment, delivering 20% longer undercarriage life than competitors in the same class when operating on rocky or gravel surfaces.

The standard bucket is constructed from high-strength wear-resistant steel plate with a high-hardness alloy cutting edge, offering a service life of over 2,000 hours in earthmoving applications.

Low operating costs are the core selling point of the GC series, and the 315D2GC delivers on this promise:

These extended service intervals alone can save ¥3,000–5,000 per year in maintenance costs compared to competitors in the same class. All maintenance points are designed to be accessible from ground level—no climbing required for oil and filter changes, significantly improving service efficiency.

Caterpillar’s nationwide parts network ensures ready availability of both genuine and aftermarket components, keeping repair costs manageable. The 315D2GC also maintains industry-leading resale value in its class—after 3–4 years of use, residual value can still reach 50%–60% of the original purchase price.

The cab meets ROPS/FOPS (Rollover Protective Structure / Falling Object Protective Structure) safety certifications. With excellent sealing and interior noise levels below 75 decibels during operation, the machine provides a comfortable working environment. The suspension-adjustable seat and multi-zone air conditioning further enhance operator comfort during long shifts.

The 315D2GC comes standard with Cat’s intelligent telematics system, enabling remote monitoring of equipment location, operating hours, fuel consumption, and fault warnings. An electronic fence function provides anti-theft protection—fleet owners can manage their equipment remotely without needing to be on-site.
