コマツ（小松製作所） PC400

The Used Komatsu PC400 Excavator is a heavy-duty hydraulic excavator engineered for demanding earthmoving tasks. This 2017 model, with approximately 2,500 operating hours, combines Komatsu's proven mechanical architecture with a robust hydraulic system to deliver consistent performance across construction, mining and large infrastructure projects. Its 40 t operating weight and powerful Komatsu diesel engine make it a dependable choice for operators seeking both traction and digging power. The excavator is powered by a Komatsu SAA6D125E-5 engine (also referenced as S6D125 in some specifications), a 11.05-litre diesel unit rated at 199 kW. The engine delivers strong low-end torque at around 2,000 rpm, enabling reliable digging force and steady swing performance under load. The factory hydraulic system and pump controls are tuned for stable, responsive operation, allowing operators to cycle attachments efficiently while maintaining fuel economy consistent with Komatsu design principles. The PC400’s frame and boom are constructed to withstand heavy cycle loads. The tested SL undercarriage and 610 mm track shoes provide a balanced ground footprint for stability on uneven terrain. Structural components and pivot points are reinforced for longevity; routine inspection and well-documented maintenance history are recommended to maximize service life and ensure predictable resale value.
