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.
New colors were introduced to WA20, WA30, WA40, and WA50 of the mini Wheel loader series. Renewing the exterior was part of this series model change.
A new type of engine was installed, passing the emission regulation that was set in 1992 and reducing fuel consumption. The sound isolation technology realized super noise reduction. WA30 through WA50 cleared "super noise reduction norm" set by Ministry of construction.
Wheel loader
It was 1949 when the first wheel loader was manufactured in Japan, however, it was not until mid 1960's when Komatsu entered the wheel loader market aligning with International Harvester. From JH series in the beginning, to the 500 series, to Komatsu's original WA series, our wheel loaders have met the needs of construction sites by scaling up, coping with the environment and adopting advanced technology such as mechatronics and IT.
