Oklahoma City, OK. Komatsu America’s new HD785-8 rigid frame off-highway haul truck has the highest in class horsepower, 1,140 HP (849 kW) and a payload capacity of 101.6 U.S. (short) / 92.2 metric tons. Available from any one of Kirby-Smith Machinery's branches throughout Oklahoma and Texas, it’s built for mining, quarry, and aggregates applications.
“Thanks to its Tier 4 Komatsu SAA12V140E-7 engine, the HD785-8 has the highest in class horsepower for the best travel performance on grade,” said Robert Hussey, product marketing manager, Komatsu America. “The wet multiple disc brakes on all four wheels provide best in class downhill brake retarding performance. Additionally, the HD785-8 delivers faster acceleration out of the pit when loaded and shorter return times to the loading area, for more hauling cycles and increased production per hour.”
With a tight turning radius of 33’ 2”, the HD785-8 provides exceptional maneuverability when spotting to be loaded and positioning to dump. The Komatsu Traction Control System (KTCS) is standard on the HD785-8. KTCS automatically applies pressure to independent brake assemblies for optimum traction in various ground conditions, without the need for differential lock-up, so steering performance is not compromised.
KomVision all-around machine monitoring system provides the operator with a bird’s-eye view of the working area on a dedicated monitor in the dash (separate monitor from the rearview monitoring system).
The HD785-8 has a 7-speed, fully automatic transmission with two selectable reverse speeds. The Komatsu Advanced Transmission with Optimum Modulation Control System (K-ATOMiCS) ensures smooth clutch engagement for a comfortable ride and reduced material spillage.
The Automatic Retard Speed Control (ARSC) automatically maintains a selected downhill travel speed (rather than engine RPM) to let operators keep their focus on the haul road.
