Since this era, the focus of domestic demand gradually started shifting from bulldozers to hydraulic shovels. Additional considerations, such as ease of operation, also became an important aspect of design.

(1970)

Komatsu Bulldozer D155A

With the proposal of "Building a New Japan", the size of construction projects including public engineering work, housing, golf courses, road work, and resource exploitation was getting bigger. As a result, the demand for development of larger equipment was rising as well.

Based on D120A, this model was developed to be more powerful. 

Weight: 32000kg

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.
