2023 Komatsu Trucks HD785-8

Power on grade. Exceptional brake-retarding performance.

With a rated payload of 101.6 U.S. tons, the HD785-8 is ready to produce in your mining, quarry, and aggregate applications. The Komatsu SAA12V140E-7 engine provides 1,140 net horsepower for excellent speed-on-grade. Oil-cooled, multiple-disc brakes on the front and rear wheels offer excellent brake-retarding capability when descending grades.

Features may include:

Auto idle shutdown

Control unnecessary fuel consumption. When the engine is idling for the set time — adjustable from five to 60 minutes — the auto idle shutdown function automatically stops and applies the parking brake.

Selectable operating modes

Your operator can choose between two operating modes: Economy mode to save fuel or Power mode for enhanced performance.

Variable Horsepower Control

The Variable Horsepower Control system is designed to deliver you high production with low fuel consumption. It automatically detects whether the machine is loaded or unloaded and selects the best horsepower setting.
