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.
The newest mechatronics and high technologies were applied to improve productivity, energy efficiency, comfort, and operator environment. Compared to the previous models, productivity was up 40% while the cost went down by 30%.
In addition to mines overseas, this model was used in construction of the Kansai International Airport that had already begun.

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.
