1990
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.
Large graders are mainly used as supporting equipment for maintenance of runways for large Dump trucks at dams, etc. This was an upgraded version, following the high reputation of -1 model. It had excellent blade operability and blade capacity was as large as 14,270kg. The lift-up cab could be adjusted with a lever, and it offered superb maintainability. The roomy cab had wide visibility, and the operator could see the edge of the blade from the sitting position, which added additional comfort to the operation.
Other Equipment
There were other construction machines built by Komatsu over the years. We can see how the various designs mirrored different eras if we look at them set against the flow of history.
