MAIN EXHIBITION ENTRANCE HISTORY OF JAPANESE BULLDOZER EXHIBITION
-

1950 OPEN

After the war, larger construction equipment was needed in order to reconstruct and cultivate devastated farmlands. At this point, Japan was developing equipment imitating what the U.S. army had brought in.

Komatsu Bulldozer D80
(1953)

Komatsu Bulldozer D80

Bulldozer D50 had been the model used for reconstruction and reclamation of farmland after the war. However, around 1949, larger bulldozers were in demand, as the need for engineering work requested by the Ministry of Construction and the development of power resources were increased. At that time, Caterpillar Inc.'s 15-ton class bulldozer D7 imported by the US army was heavily used in Japan, and this D80 model was domestically produced based on the D7.

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.
