Komatsu's HM460-6, an all-new addition to the company's ADT lineup, is designed around a new high-output powertrain, an advanced traction control system, and a new operator environment — and it's ready for demanding applications across challenging, versatile terrain.
The new ADT has a rated payload capacity of 46.3 tons, compared to the 44.2-ton capacity of Komatsu's HM400-5, allowing operators to haul a greater volume of material with each cycle.
The new Komatsu DBA127 engine is equipped with a two-stage turbocharger system and delivers 518 gross horsepower at 1,700 rpm. It is paired with a new nine-speed Komatsu transmission and intelligent gear control. Komatsu says that this ADT's increased torque at lower engine speeds supports strong acceleration, improved hill-climb capability, and efficient power delivery under load. It has no EGR system, uses less fuel, and has extended service intervals.
The traction performance of the HM460-6 will keep operators comfortable and confident across soft surfaces and on grades while reducing spillage and tire wear. The Komatsu Traction Control System, paired with cross-axle differential locks, helps maintain traction on soft, uneven, or muddy ground, and the hydro-pneumatic suspension system delivers comfort and stability. It continuously monitors wheel speed and slip and will automatically apply braking force to individual wheels when traction is lost.
Komatsu's new four-pillar cab has 16 percent more glass area and a 43 percent reduction in blind spots compared to the HM400-5. The control layout has been redesigned to group high-use functions within easy reach, and a high-resolution 8-inch machine monitor paired with a 10-inch sub-monitor provides access to payload data, machine information, and rear-view camera.
Cruise control and automatic retard speed control help maintain consistent downhill speeds. Hill start assist prevents rollback on steep grades. The new ADT also features a rollover prevention system that monitors vehicle speed and rear frame angle, providing alerts and limiting machine functions when tipping becomes a risk. Operators can review the status of their brakes by using the new brake inspection guidance.
