Used Komatsu PC450-8 Crawler Excavator

The used Komatsu PC450-8 excavator stands out in the heavy machinery market, retaining impressive advantages and performance that meet the demands of construction, mining, and earthmoving projects—even after years of service.​

Durability is its foundation. Crafted with high-strength steel for the boom and arm, plus a reinforced undercarriage, it resists wear from rough terrains like quarries or construction sites. This sturdiness means used units still offer long-term reliability, a key plus for cost-conscious buyers.​

In terms of power, it’s equipped with a 326 HP Komatsu SAA6D125E-6 engine, delivering consistent torque for fast cycle times. It can lift up to 45,000 kg and dig to a maximum depth of 7.4 meters, outperforming many peers in its class for heavy lifting and deep excavation tasks. Even as a used machine, its hydraulic system remains precise, ensuring smooth operation for tasks like loading trucks or grading.​

Fuel efficiency is another highlight. Thanks to Komatsu’s Intelligent Machine Control (KMC) system, the engine adjusts output based on workload, cutting fuel consumption by up to 15% compared to older excavators. This lowers operational costs, a big advantage for long-term projects.​

The operator experience is also strong. The cab is spacious, with ergonomic controls, low noise levels, and clear visibility—reducing fatigue during long shifts. Maintenance is easy too: accessible filters, fluids, and diagnostic ports minimize downtime, while Komatsu’s global service network ensures quick access to parts for used units.​

Overall, the used Komatsu PC450-8 combines durability, power, efficiency, and user-friendliness, making it a cost-effective choice for businesses needing reliable heavy equipment.
