Used Komatsu PC400 Excavator Guide: Large Class Export Buying Tips
Release time: 2026-10-23
The Komatsu PC400 class (including PC400-7 / PC400-8 variants) is a large excavator for quarry faces, mining support and heavy loading. Landing one from China only makes sense if you verify structure and undercarriage carefully — repair costs scale fast at this size.
When a PC400 is the right buy
Choose PC400 when 20-ton machines cycle too slowly on your rock or when you need deeper reach. For general civil work, a PC200/PC210 is usually enough and cheaper to ship.
High-cost inspection items
- Boom and arm cracks, especially around the boom foot and stick nose
- Swing bearing play and grease path
- Track group remaining life (shoes, pins, bushings, rollers, idlers, sprockets)
- Main pump output and abnormal metal in filters
- Engine blow-by and turbo condition on cold start
Shipping reality
PC400-class machines almost always move as bulk or heavy flat-rack cargo. Freight is a big share of landed cost, so confirm port crane limits before you book. We can share yard videos and a packing proposal from Shanghai.
