Komatsu PC4000 vs CAT 6060: Comparison
The Komatsu PC4000 and CAT 6060 are both massive, 400-to-600-ton class hydraulic mining shovels built for heavy-duty earthmoving. The PC4000 (1,875 hp) is favored for its balanced power and lower fuel consumption, while the CAT 6060 (3,000 hp) dominates in raw payload, bucket capacity, and high-volume production.

Key Differences & Performance
- Productivity & Capacity: The CAT 6060 is a significantly larger machine. It features a
bucket and handles payloads of up to 61 tonnes per pass. This makes it an efficient 4-pass match for a large mining haul truck like the CAT 793. By comparison, the Komatsu PC4000 carries a
bucket, making it suited for slightly smaller-scale truck pairings.
- Fuel Economy vs. Raw Power: Komatsu machines are heavily engineered around the balance of power and fuel consumption, resulting in highly efficient operations. CAT delivers raw hydraulic power designed for brutal digging conditions and higher total tonnage output.
- Maintenance: Both units are modular and designed with serviceability in mind. The Komatsu utilizes features like the Eliminator oil filter system to drastically extend oil change intervals, while CAT offers a popular ground-level accessible, retractable service station.
- Dealer Network: CAT generally has the upper hand regarding global parts availability and resale value, thanks to its widespread dealer support
