1960 OPEN

Liberalization of trade brought Japan demand from abroad and the opportunity to raise Japan's technological advancements to a world-class level. The introduction of large-scale power sources took place, which accelerated development of larger equipment.

Back then, "pound" was the unit of load capacity for bidding, and the price of the equipment itself was also determined by the capacity. Load capacity of HD150 was 15 tons (33,600lbs). An increase of capacity was desired because, if it became 18 tons (40,320lbs), it could be ranked as a higher class.

The specifications were similar to those of HD150-6. It gained a good reputation as a reliable and reasonably priced Dump truck in the market, and was used at mid size mines and engineering projects. As the scale of construction became larger, the demand was later shifted toward 20 - 30 ton Dump trucks.

Load capacity: 18,000kg

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.
