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.
This was one of the models that Komatsu exhibited at CONEXPO, the exhibition of construction equipment held in Houston, Texas of The United States in January 1981. It was the largest bulldozer in the world at that time utilizing the newest electronics technology to cut down the cost of operation significantly at large mines.
Since its first emergence in 1951, it took only 50 years for the hydraulic shovel to establish its primary position on construction sites worldwide. Its size ranges from mini to super size depending on the scale of construction, and during the half century, it kept evolving by achieving a minimum rear-swing radius and adapting styles that would work with characteristics of each site. Mirroring the movement of a human hand, a hydraulic shovel will continue to evolve during the 21st century.
