It meets EPA Tier 3/EU Stage IIIA emission standards, and is widely used in large - scale mining, dam construction and road - and - bridge infrastructure projects for its strong digging force and stable performance.
The PC450-8 is equipped with the KOMATSU SAA6D125E - 5 6 - cylinder turbocharged diesel engine (257kW/1900rpm, 11.04L displacement), featuring high - pressure common rail and cooled EGR technology:
- Strong Power Output: The engine delivers a maximum torque of 1420N·m, enabling the excavator to easily handle hard rock and heavy - load digging tasks, with a maximum climbing capacity of 70% to adapt to steep slopes in mining areas.
- Eco - Friendly & Cost - Saving: It meets EPA Tier 3/EU Stage IIIA emission standards, ensuring smooth customs clearance in emerging markets without modification. The intelligent fuel injection system reduces fuel consumption by 12% compared with peers, at 18-20L per working hour, suitable for long - term high - frequency operations.
- Long - Lasting Durability: A double - layer air filter and high - precision fuel filter extend the engine's service life to 18,000 hours—35% longer than the industry average, reducing downtime in harsh mining environments.
It is matched with KOMATSU's proprietary CLSS closed - center load - sensing hydraulic system (main pump maximum flow of 580L/min), ensuring efficient and stable operation:
- Super Strong Digging Force: The maximum bucket digging force reaches 278kN, and the maximum arm digging force is 233kN, easily breaking hard rock and compacted soil, improving operation efficiency by 25% in large - scale earth - moving projects.
- Precise & Smooth Control: The hydraulic system realizes independent control of the boom, arm and bucket, with a swing speed of 9.1rpm and a maximum travel speed of 5.5km/h, enabling flexible operation in narrow mining areas and construction sites.
- Low Maintenance Cost: The hydraulic oil replacement cycle is extended to 5,000 hours, and imported seals reduce the hydraulic leakage rate by 90%, lowering long - term maintenance costs significantly.
The PC450-8 adopts a variable - gauge undercarriage and a spacious FOPS - certified cab, ensuring stability and operator comfort:
- Superior Stability: The variable - gauge undercarriage (track gauge 2890mm extended/2392mm retracted) enhances stability during heavy - load digging, and the 600mm - wide track shoes improve ground contact area and traction on soft ground.
- Comfortable Operation: The ergonomic seat with suspension, low - noise cab (≤75dB) and user - friendly control levers reduce operator fatigue during 10 - hour+ shifts. The KOMTRAX system provides real - time data on fuel consumption, working hours and fault alerts.
- Excellent Maneuverability: The compact rear - end swing radius (3605mm) allows safe rotation in confined spaces, while the reinforced boom and arm (7060mm/3380mm length) ensure structural strength during heavy - load operations.
The PC450-8 uses a high - strength steel frame and a reinforced counterweight, ensuring operational safety in harsh conditions:
- Comprehensive Safety Protection: The FOPS/ROPS - certified cab, anti - slip walkways and hydraulic safety lock prevent accidents. The double - circuit braking system ensures a short braking distance even on slippery slopes.
- Corrosion & Wear Resistance: The anti - corrosion paint resists salt spray in coastal areas and chemical corrosion in mining areas, extending the machine's service life by 40%. The reinforced track frame and heavy - duty idlers handle rough terrain easily.
- Easy Maintenance: Daily maintenance points (oil, filters) are accessible at ground level, cutting maintenance time by 30%. Common spare parts (filters, seals, hydraulic hoses) are available in KOMATSU's regional warehouses (Dubai, Singapore, Johannesburg) with 3-7 - day delivery.
With an overall size of 12040×3580×3660mm and an operating weight of 45,125kg, the PC450-8 has a robust body. The variable - gauge undercarriage and large counterweight ensure stability during heavy - load digging, and the KOMATSU green paint resists corrosion in harsh environments.
The SAA6D125E - 5 engine (257kW) and CLSS hydraulic system deliver a maximum digging depth of 7790mm and a digging force of 278kN. The optimized heat dissipation system ensures continuous operation in 50°C high - temperature environments in the Middle East and Africa.
The KOMTRAX - equipped dashboard displays real - time data, and the ergonomic control levers reduce operating force by 30%. The spacious cab with a wide field of vision ensures safe and efficient operation during long shifts.
