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.
Mid sized models are often used for a longer duration of work such as material transportation/loading, snow removal, and are required to be easy to operate and comfortable for long hours. To meet these requirements, Komatsu made a model change of WA300, WA350, WA400, and WA450. The change included a larger bucket, an engine with larger output, and an advanced transmission system, improving both ease of operation and comfort.
These were also fitted with the eco friendly engine that cleared the emission regulation set by the Ministry of construction.
WA450 Bucket capacity: 3.8m3
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.
