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.
Productivity of this model was raised to the next level by adopting a large bucket of 20m3 capacity, the maximum excavating and pulling power of its class, and shortening the cycle time with the modulated clutch system. Its roomy dumping clearance and dumping reach were best matched for 150 to 200 ton Dump trucks. Additionally, its high lift format made it possible to load onto 240 to 300 ton Dump trucks.
The hydraulic and electric control technologies created the "advanced joystick steering system" that let an operator pull the lever at any degree he needed, providing a delicate steering experience that fit the sensitivity of personal preferences. It was also equipped with the "total management system" that reduced the running cost by constantly monitoring the vehicle. The color graphic console with easy touch panel operation helped visual recognition as well.
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.
