Used Komatsu PC400-8 excavator

Komatsu PC400-8 is not the machine I use for every heavy job. It is better for buyers who need a large Komatsu excavator for normal earthmoving, road work, river cleaning, slope trimming, foundation excavation and loose material loading, but do not want the higher ownership pressure of a heavier quarry-position machine.

We usually keep around three PC400-8 machines in stock. Working hours may range from about 1,000 to 8,000 hours, but exact stock changes and should be confirmed before quotation. Paint condition may include original paint or full repainting. Many original-paint machines we handle may still keep around 80% undercarriage condition, while fully refurbished machines often have new undercarriage prepared for resale.

PC400-8 is attractive when the job site is narrow, muddy or needs frequent transfer. Many buyers use it for mountain-side working faces, river dredging, soft soil jobs, roadbed work and short-term earthwork projects. It can be easier to move and manage than PC450-8 when the job does not require continuous hard rock loading or 24-hour quarry production.

PC400-8 and PC450-8 should not be treated as the same machine. PC400-8 is better for general 40-ton class work, softer ground, lower transport pressure and projects using 30–35 ton dump trucks. PC450-8 should be checked separately when the buyer needs heavier structure, larger quarry loading ability, stronger stability with big rock and long-hour mining work.

PC400-8 commonly uses the SAA6D125E-5 engine family, but the actual engine plate must be confirmed on each machine. Before comparing price, confirm the real nameplate, engine plate, undercarriage, boom foot, counterweight, hydraulic response, structure repair marks and current working video.

Before quotation, ask for the exact working video. Check cold start, smoke, idle sound, hydraulic response, swing, travel, undercarriage, boom foot, arm welds, swing bearing area, leakage, nameplate and loading proof. A clean repaint or good-looking sticker cannot replace real machine inspection.

Final Komatsu PC400-8 specs should follow the current machine, nameplate, engine plate and actual configuration. PC400 weight, bucket size, lifting condition, track shoe width and transport size may vary by machine condition and export preparation.

For Komatsu PC400-8 specs, PC400 weight or PC400 engine details, the exact machine should be confirmed by video, plate details and photos.
