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.
PC1500 was a super sized loading shovel that was unveiled at CONEXPO'81. In the following year, only three units were sold. Its mass production began in 1984. It was also in 1984 when OLSS (Open Center Load Sensing System) was installed in PC200-3 with mechatronics as a part of an energy saving hydraulic system, however, the PC1500 was already equipped with the device.
Weight: 150000kg, Bucket capacity: 8.5m3(Standard)/14m3(Coal)
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.
