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.
WA600 and WA800 were fully upgraded for the first time in 12 years. Their bucket capacity and engine output were improved significantly. Adopting a new structure of two staged hydraulic system increased both speed and power, allocating the appropriate amount of oil when lifting a boom, excavating, and scooping. WA600 was also built more environmentally friendly, passing the emission regulation in Europe and the United States.
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.
