Equipped with the KOMATSU SAA6D114E-3 engine, this excavator delivers a rated power of 180 KW with remarkable efficiency. The engine features advanced fuel injection technology that optimizes fuel atomization, ensuring thorough combustion and reducing unnecessary fuel waste. Its intelligent cooling system adjusts fan speed based on operating temperature, further minimizing energy consumption. This engineering allows the excavator to maintain consistent power output even in high-load conditions, such as continuous digging in compacted soil.
The hydraulic system of the Komatsu PC300-7 is engineered for precise control and responsive operation. It employs a closed-center load-sensing system that adjusts oil flow according to the actual workload, reducing energy loss during idle movements. The main control valve is designed to minimize pressure drops, ensuring that more power is transferred to the working equipment. This results in smooth bucket movements and accurate positioning, which is particularly beneficial for tasks requiring fine operations, such as grading or placing materials.
Building on its advanced engine and hydraulic design, the excavator achieves 8-10% better fuel efficiency compared to similar products. In practical tests, it consumes approximately 12-15 liters of fuel per hour during medium-intensity operations, which translates to significant cost savings over extended project durations. This efficiency does not compromise performance, as the machine maintains its 1m³ standard bucket capacity and consistent digging force.
Key structural components, including the boom, arm, and undercarriage, are constructed with high-tensile strength steel. The boom and arm undergo stress relief treatment to reduce fatigue damage, contributing to a design lifespan of 20,000 hours. The track links are hardened to resist wear, while the bucket is reinforced with extra steel plates at high-stress points, such as the cutting edge. These features enable the excavator to withstand abrasive materials and rough terrain commonly encountered in mining and earthwork projects.
Thanks to Komatsu's established brand reputation and the model's widespread use in global markets, the Komatsu PC300-7 maintains a retention rate of over 75% after three years. This is supported by the availability of replacement parts and a large user base, which ensures consistent demand for pre-owned units. Many construction companies prefer this model due to its predictable maintenance costs and proven reliability, further stabilizing its market value.
The excavator is designed with ease of maintenance in mind. Major service points, such as the engine oil filter, fuel filter, and hydraulic oil reservoir, are strategically placed for quick access. The side panels can be fully opened, providing unobstructed views of internal components during inspections. Additionally, Komatsu's diagnostic system allows technicians to identify issues through error codes, reducing troubleshooting time. This design minimizes downtime for routine maintenance, enhancing overall operational efficiency.
In earthwork engineering, the Komatsu PC300-7 used excavator demonstrates strong capabilities. Its daily operating volume can reach 800m³, which can meet the needs of large-scale earthmoving operations. Whether it is site leveling, foundation excavation, or soil transportation, this excavator can complete the tasks efficiently.
The excavator is also suitable for mining operations, especially when equipped with a 1.4 m³rock bucket. It can handle the excavation and loading of mineral resources with relative ease, adapting to the hard and complex geological conditions in mining areas.
In municipal construction projects such as road construction, pipeline laying, and greening projects, the Komatsu PC300-7 used excavator shows good maneuverability and flexibility. Its moderate size allows it to work in relatively narrow spaces, ensuring the smooth progress of municipal construction.
