Komatsu WA900 Wheel loaders tech specs

Overview

The Komatsu WA900 (WA900-3E0) (2007–2019) is a 107.35-ton wheel loader aimed at mine operators, large quarry fleets, aggregate producers, and contractors that move very high volumes of material. Its 672 kilowatt Komatsu SAA12V140E-3 engine, 11.5 cubic meter bucket, 41-ton lifting capacity, and 665.9 kN breakout force make it suitable for loading large haul trucks, handling blasted rock, feeding crushers, and managing major stockpiles.

Expert rating: 5 stars

Performance & Efficiency

The 672 kilowatt Komatsu SAA12V140E-3 engine produces up to 4,090 Nm of torque for pushing into dense rock piles and maintaining loaded travel performance. Its 665.9 kN breakout force helps fill the 11.5 cubic meter bucket in heavy material, while the variable-displacement piston pump delivers 1,015 liters per minute at 314 bar for responsive lifting, tilting, and rack-back movements. The 41-ton lifting capacity and 57.4-ton tipping load provide the stability needed for repetitive loading in mine and quarry production.

In Comparison

Komatsu WA500: Easier to transport and more practical for general quarry and aggregate work, but offers far less bucket capacity, lifting strength, and breakout force.
Komatsu WA600: A heavy production loader with lower operating weight and simpler site logistics, but it remains substantially smaller than the Komatsu WA900 in loading capacity and hydraulic output.
Komatsu WA900: Provides the highest production potential of the three, combining a 107.35-ton platform, 11.5 cubic meter bucket, 41-ton lifting capacity, and 665.9 kN breakout force.

Final Verdict

Rated 5 stars, the Komatsu WA900 is a high-production wheel loader within the AED 735,000–2,750,000 range. Its large bucket, high engine output, substantial lifting capacity, and heavy-duty hydraulic system make it a practical choice for mines, major quarries, and large aggregate operations where production volume justifies the high ownership and operating costs.
