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.
A microcomputer was added to the energy saving hydraulic system, OLSS(Open Center Load Sensing System), that was standard equipment on the PC-2 Series and had a good reputation, which upgraded OLSS to "Electric OLSS". It was the world's first control system that made full use of mechatronics. The design was also reworked, giving the series an original style.

Hydraulic excavator
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.
