Product Overview

The Komatsu PC450 series is a 45-ton mining-class heavy-duty hydraulic crawler excavator, purpose-built for large-scale overburden stripping, open-pit quarrying and heavy infrastructure construction. Represented by the proven PC450-7 and PC450-8 generations, it is powered by a high-displacement six-cylinder turbocharged aftercooled diesel engine and matched with Komatsu's proprietary closed-center load-sensing hydraulic system, delivering class-leading digging force, exceptional structural durability and reliable round-the-clock heavy-load operation capability. As a flagship model in the 40–50 ton segment, it is the standard core equipment for open-pit mining, highway and railway subgrade construction, deep foundation pit excavation, river dredging and large-scale infrastructure projects worldwide.

All our used PC450 excavators are sourced from formal authorized channels with 100% original core components, no structural collision or rollover history, and traceable regular maintenance records. Each unit undergoes a strict 120-point pre-delivery comprehensive inspection, including engine load test, hydraulic system full-pressure detection, track wear measurement and full electrical circuit verification. Purchasing this used Komatsu heavy excavator only costs 40%–55% of a brand-new unit, with extremely high residual value and outstanding return on investment, making it the preferred choice for large construction contractors, mining operators and heavy equipment rental fleets.

Core Product Advantages

• Original Komatsu SAA6D125E-5 six-cylinder water-cooled turbocharged aftercooled diesel engine, net power 257 kW (345 HP) @ 1900 rpm, 11.04L large displacement, robust low-end torque output, proven reliability and ultra-long service life, with fuel consumption of only 26–34 L per hour, adaptable to low-grade diesel in various regions and 24-hour continuous heavy-load operation.

• Advanced closed-center load-sensing hydraulic system (CLSS) with HydrauMind intelligent control, precise flow distribution and smooth coordinated compound actions; equipped with Power / Economy / Heavy Lift / Breaker multiple working modes, which can be switched freely according to different operation demands, effectively improving work efficiency and reducing fuel consumption.

• Outstanding heavy digging performance: bucket breakout force reaches 278 kN, arm crowd force reaches 233 kN, matched with standard 2.1 m³ heavy-duty rock bucket, highly efficient for large-scale overburden stripping, quarry aggregate loading and bulk material transportation; standard high-flow auxiliary hydraulic pipeline, compatible with hydraulic hammer, ripper, grab, shear and other heavy attachments for multi-purpose operation.

• Heavy-duty reinforced X-shaped chassis frame with 600 mm wide triple-grouser steel track, heavy-duty track rollers and grease-sealed track links, strong impact resistance for hard rock digging and rough terrain operation; three-speed travel mode with maximum speed of 5.5 km/h, gradeability up to 70% (35°), adapting to various complex mining and construction terrain.

• Ultra-high rigidity working device: high-strength thickened steel boom and stick with internal partition reinforcement and full box welded structure, strong impact resistance for hard rock excavation and heavy loading; maximum digging depth reaches 7,790 mm and maximum digging reach exceeds 12 meters, covering most large-scale construction and mining project demands.

• Optimized maintenance-friendly design: wide side-opening engine hood and swing-out cooler module provide easy access for daily inspection and maintenance; centralized lubrication points and large-capacity filter elements extend maintenance intervals, reducing downtime and operating cost; large fuel-water separator effectively protects the engine from poor-quality fuel.

• Spacious fully enclosed ergonomic cab with wide panoramic vision, viscous cab damper mounting for low vibration and noise, adjustable air-suspension shock-absorbing seat and centralized control layout, effectively reducing operator fatigue during long-hour heavy-load work; equipped with safety lock lever and ROPS/FOPS protection structure to ensure construction safety.

• Transparent and reliable used condition: genuine unmodified hour meter reading, no abnormal oil leakage from engine, hydraulic pump and control valve; no cracks, deformation or welding repair traces on boom, stick, chassis frame and revolving platform; undercarriage components maintain good wear condition.

• Full one-stop global export service: support third-party pre-shipment inspection by SGS, BV and other authoritative institutions; professional team handles customs declaration, shipping booking, container loading supervision, and provides complete set of export documents. Lifelong 24/7 online technical support for maintenance and fault troubleshooting.
