1980
More and more innovative technologies were applied to products with a heavy focus on hydraulic shovels. Using mechatronics for engine control was one of the examples of Japan's advanced electronics technology that surpassed the world standards.
Komatsu entered the field of the 20-ton class crane. This model worked well in high places. Selecting between two wheel, four wheels, or crab running drive, was simply done with a switch at the driver's seat, which made operation in small spaces and inside buildings easy.
It also offered stable running, easy operation, low noise, and low fuel consumption.
Maximum rating load: 20 tons
Other Equipment
There were other construction machines built by Komatsu over the years. We can see how the various designs mirrored different eras if we look at them set against the flow of history.
