With a payload of more than 100 tons and the highest net horsepower in its class (1,140 hp), Komatsu’s new HD785-8 rigid frame off-highway haul truck is the beast you need for mining, quarry or aggregate operations.

 

Despite its size, the HD785-8 is nimble, with a tight turning radius of just a little over 33 feet. That maneuverability pays off when the operator is positioning the truck for loading or dumping.

 

“The HD785-8 has excellent travel performance on grade,” noted Robert Hussey, product marketing manager for Komatsu America. “The haul truck delivers fast acceleration out of the pit,” and downhill travel is easy, he added. “Wet multiple disc brakes on all four wheels provide great downhill brake-retarding performance.” The driver can focus on the road because the Automatic Retard Speed Control system maintains a selected downhill travel speed without relying on engine RPM.

 

The truck also has traction control to maintain optimum traction in different ground conditions. Material spillage is reduced, thanks to the smooth clutch engagement on the seven-speed automatic transmission.

 

“The new cab keeps operators comfortable during long shifts, resulting in high production per hour,” Hussey said. The redesigned cab includes upgraded seating, a rearview monitoring system, and Komtrax Plus telematics system.

 

The KomVision machine monitoring system is another productivity and safety-enhancing feature. It gives the operator a bird’s eye view of the entire working area, displayed on a dedicated monitor in the dash. The LED lighting package also increases visibility and safety in all working conditions.

 

The H785-8 is designed for easy maintenance and low ownership costs. There’s no requirement for DEF, for instance. Filters, grease points, and fuel fill coupler are all grouped together, and the service center is at ground level.
