코마츠 450

The Komatsu PC450-8 stands as a flagship heavy-duty excavator engineered to deliver exceptional power, reliability, and efficiency in the most challenging construction, mining, and infrastructure projects. Powered by the robust SAA6D125E-5 diesel engine, this machine generates a net power output of 257 kW (345 HP) at 1,900 rpm, ensuring superior digging force and hauling capacity to tackle large-scale earthmoving, rock excavation, and material handling tasks with ease. With an operating weight of 45,125 kg, the PC450-8 strikes an optimal balance between stability and maneuverability, featuring a crawler undercarriage with a track width of 600 mm (optional 700 mm for enhanced flotation) and a ground pressure of 83 kPa, allowing it to navigate rough terrains, soft soils, and confined job sites without compromising performance. At the heart of its functionality is a high-capacity bucket (standard 2.1 m³, optional up to 2.7 m³) paired with a powerful hydraulic system that delivers a maximum digging force of 278 kN (bucket) and 245 kN (arm), enabling efficient penetration into hard rock and compacted soil. The excavator’s digging range is equally impressive, with a maximum digging depth of 7,470 mm, a maximum digging height of 11,020 mm, and a maximum reach of 11,280 mm, making it versatile for tasks ranging from deep trenching to high-reach demolition. Komatsu’s advanced fuel-saving technologies, including the Hydraulic System with Variable Displacement Pumps and the Auto Idle Stop function, optimize fuel consumption, reducing operational costs while minimizing environmental impact—achieving an average fuel efficiency of 18-22 L/h depending on the application. Designed with operator comfort and safety in mind, the PC450-8 features a spacious, climate-controlled cab with an ergonomic layout, including a fully adjustable suspension seat, intuitive control levers, and a large color monitor that displays key machine data (fuel level, engine temperature, hydraulic pressure) and maintenance alerts. The cab is mounted on viscous dampers to reduce vibration, while sound insulation minimizes noise levels (interior noise: 72 dB(A)), ensuring a comfortable working environment during long shifts. Safety enhancements include a ROPS (Roll-Over Protective Structure) and FOPS (Falling Object Protective Structure)-certified cab, rearview cameras, and wide-angle mirrors for enhanced visibility, reducing the risk of accidents on busy job sites. Durability is a cornerstone of the PC450-8’s design, with a reinforced boom and arm constructed from high-tensile steel, thickened bucket teeth, and wear-resistant components that withstand heavy loads and abrasive materials. The machine’s undercarriage is built for longevity, featuring sealed track links, heavy-duty rollers, and idlers with automatic lubrication systems to reduce friction and extend service life. Routine maintenance is simplified with easily accessible service points, a centralized lubrication system, and Komatsu’s Komtrax telematics system, which allows remote monitoring of machine performance, location, and maintenance schedules—enabling proactive servicing and minimizing downtime. Versatile by design, the Komatsu PC450-8 can be equipped with a range of attachments, including breakers, grapples, rippers, and tilt buckets, adapting to diverse applications such as mining, quarrying, road construction, building demolition, and agricultural land development. Whether working in extreme temperatures, high-altitude regions, or wet conditions, the PC450-8 maintains consistent performance, thanks to its robust engine cooling system, water-resistant electrical components, and corrosion-resistant finishes. Backed by Komatsu’s global network of service centers and genuine parts availability, the PC450-8 is a reliable investment for businesses seeking a high-performance excavator that combines power, efficiency, and durability to meet the demands of today’s most challenging job sites.
