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.
PC400 was developed for gathering gravel, soil, and crushing stones. Like PC220 and PC300, it used the energy saving hydraulic system and was fitted with the Cummins engine that had excellent fuel economy. It used the same large link as the bulldozer D80 for improved durability.

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.
