Komatsu HM400-5 Water Truck (Conversion) Specifications
Dumpers Specs
The Komatsu HM400-5 Water Truck conversion is a heavy-duty dust suppression and water transport solution built on the highly reliable HM400-5 articulated dump truck platform. Engineered to withstand the harshest Australian mining, quarrying, and civil construction environments, this machine combines Komatsu’s advanced drivetrain technology with a high-capacity water tank integration. Its articulated steering and hydro-pneumatic suspension ensure exceptional stability and traction across challenging, uneven terrains.
Equipped with a powerful, fuel-efficient Komatsu engine, the HM400-5 conversion delivers outstanding performance while meeting strict emission standards. The spacious, ergonomically designed cab provides operators with superior visibility and comfort, reducing fatigue during long shifts. Whether deployed for haul road dust control, soil compaction, or large-scale water transfer, this robust water truck is a vital asset for maintaining safety and productivity on major Australian worksites.

Additional Information
The Komatsu HM400-5 features the advanced Komatsu Traction Control System (KTCS), which automatically monitors wheel slippage and applies independent brakes to maintain optimum traction in muddy or slippery conditions without compromising steering performance. Additionally, the Komatsu Advanced Transmission with Optimum Modulation Control System (K-ATOMiCS) provides smooth, electronically controlled gear shifts to eliminate torque cut-off, enhancing operator comfort and powertrain longevity. The conversion to a water truck utilizes these robust base features to deliver a highly stable, efficient, and durable dust-suppression platform tailored for demanding Australian operations.
