(1969)

Komatsu Bulldozer D355A

This large bulldozer was developed for oversea mines. Compared to the smaller models such as D120A and D250A, the characteristics of work done by D355A included operation of the ripper that was attached to the rear part of the body.

The very first unit exported overseas went to mines in Hamersley Australia and was put into heavy use digging iron ore, whose iron density is more than 70%.

Weight: 48000kg

Bulldozer OPEN

Since its first emergence in 1951, it took only 50 years for the hydraulic shovel to establish its primary position on construction sites worldwide. Its size ranges from mini to super size depending on the scale of construction, and during the half century, it kept evolving by achieving a minimum rear-swing radius and adapting styles that would work with characteristics of each site. Mirroring the movement of a human hand, a hydraulic shovel will continue to evolve during the 21st century.
