1970
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.
This was the beginning of the 500 series upgraded from the JH series. 510 was a renewed model of JH30B that was jointly developed with International Harvester as the first project after the partnership. Unlike JH30B with the rigid frame, 510 had articulated steering which greatly improved workability and mobility.
Bucket capacity: 1.2m3
The two-toned color of its exterior gave the 500 series a completely new look.
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.
