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.
PC650 is a large loading shovel equipped with an electrically controlled hydraulic system like PC1500. Though it was improved later, this complicated hydraulic pluming was called "Jungle Gym Spaghetti Tube" among the developers.
Its quality was drastically improved with PC650-3, which eventually led to development of larger equipment such as PC750 and PC800.

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.
