Since this era, the focus of domestic demand gradually started shifting from bulldozers to hydraulic shovels. Additional considerations, such as ease of operation, also became an important aspect of design.
As the number of larger constructions rose, so did the amount of soil transportation, gravel gathering, and stone crushing, which led to the higher demand for a larger loader in order to increase work speed and reduce cost. The sales of JH90E, the largest Wheel loader in Japan for exploded fallen rocks, grew rapidly.
Bucket capacity: 3.5m3
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.
