Komatsu WA600 Wheel loaders tech specs

Overview

The Komatsu WA600 (WA600-3) (1994–2005) is a 44.16-ton wheel loader aimed at quarry operators, aggregate producers, mining support fleets, and contractors that regularly handle heavy material. Its 389.3 kilowatt turbocharged Komatsu SAA6D170E-3 engine, 2.1 cubic meter bucket, 31-ton lifting capacity, and 368.75 kN breakout force make it suitable for loading trucks, moving rock, feeding processing equipment, and managing large stockpiles.

Expert rating: 4 stars

Performance & Efficiency

The 389.3 kilowatt Komatsu SAA6D170E-3 turbocharged engine produces up to 2,250 Nm of torque for pushing into dense stockpiles and maintaining performance under load. Its 368.75 kN breakout force supports bucket filling in compacted material, while the 492.05-liter-per-minute variable-displacement piston pump handles lifting, tilting, and rack-back functions. The 31-ton lifting capacity and 33.2-ton tipping load provide strong working stability, while the 33.5 kph maximum travel speed supports movement across large production sites.

In Comparison

Komatsu WA470: Easier to transport and better suited to general construction and medium-volume loading, but provides considerably less lifting capacity and breakout force.
Komatsu WA500: A closer alternative for quarry and aggregate work, with lower operating weight and easier site logistics, but less overall lifting strength than the Komatsu WA600.
Komatsu WA600: Provides the strongest production package of the three, combining a 44.16-ton platform, 31-ton lifting capacity, and 368.75 kN breakout force for heavy material handling.

Final Verdict

Rated 4 stars, the Komatsu WA600 is a capable heavy wheel loader within the AED 320,000–490,000 range. Its strong lifting capacity, high engine output, substantial tipping load, and heavy-duty hydraulic system suit quarry and aggregate work, but buyers should inspect the engine, transmission, articulation joint, hydraulics, tires, and service history carefully due to the machine’s age.
