Komatsu Dump truck HD785
(1982)

Komatsu Dump truck HD785

Since HD680 in 1974, the demand for 85-ton class Dump trucks was rising, as larger models were desired more at mines.

Komatsu first developed HD780, which it shared many parts with. Then they built HD785 with a more powerful engine and larger tires, which was commercialized. 

Load capacity: 78,000kg

Dump truck OPEN

The history of the dump truck as a transporting vehicle is also the history of increasing the amount of loading to improve productivity at construction sites. At mines especially, new technology is being introduced consistently even today. Enlarging the size by mechanical and electrical formulas, and adding the GPS control system are some of the examples.
