Komatsu America’s New HD785-8 Off-Highway Truck with High Horsepower

By Pulltarps Mfg | December 19, 2019

Komatsu America’s new HD785-8 rigid frame off-highway haul truck, with a Tier IV Komatsu SAA12V140E-7 engine, has the highest in class net horsepower, 1,140 hp (849 kW) in North America. With a payload capacity of 101.6 tons (92.2 t), it’s built for mining, quarry and aggregates.

“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 ft. 2 in. (10 m), the HD785-8 provides enhanced 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.
