Komatsu Dump truck HD325
(1979)

コマツ ダンプトラックHD325

7 years after development of HD320, in 1972, this model was built as high-end equipment to cope with the competitive market. The main differences from HD320 include increased power output with the new engine, a full automatic transmission, larger diameter tires and a higher loading height limit. In addition to domestic sites, it was used for the construction of a new airport in Hong Kong.

Load capacity: 32,000kg

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.
