Komatsu America introduce new HD785-8 off-highway truck

Komatsu America’s new HD785-8 rigid frame off-highway haul truck, with a Tier 4 Komatsu SAA12V140E-7 engine, has the highest net horsepower in North America.

“The HD785-8 has excellent travel performance on grade, and wet multiple disc brakes on all four wheels provide great downhill brake retarding performance,” said Robert Hussey, Product Marketing Manager, Komatsu America. “The HD785-8 delivers fast acceleration out of the pit and the new cab keeps operators comfortable during long shifts, resulting in high production per hour.”

With a tight turning radius of 33’ 2”, the HD785-8 provides good manoeuvrability. 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.

The 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 rear-view 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.

Furthermore, 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.
