1990 OPEN

While equipment built to accommodate urban environments, by generating less noise, vibrations and emission, became more common, super sized equipment that could withstand harsh working conditions in places like giant mines were also developed.

Komatsu Bulldozer D575A

D575A was developed as the worlds largest bulldozer. It is used at large mines and stone crushing sites. The third one in production was supplied as the first unit for domestic use. A total of nine trailers and trucks were used for its transportation.

Weight: 129200kg

Komatsu Bulldozer D575A

Following D575A, the D575A Superdozer was launched. It can hold a scooping posture by tilting the blade backward toward the operator's side. This allows loaded soil to work as a counter weight, generating more power. Compared to D475A, it could carry twice as much soil. This technology was patented in the United States.

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.
