While equipment built to accommodate urban environments, by generating less noise, vibrations and emission, became more common, super sized equipment that could withstand harsh working conditions in places like giant mines were also developed.
New Avance was the first 20 ton class model that used the round form. It was fitted with fine control and CLSS (Closed Center Load Sensing System) and a pressure compensation hydraulic system that supported multiple operations. It was an ideal hydraulic system that advanced the quality of OLSS up to PC200-5.
PC200-6：Weight: 19450kg, Bucket capacity: 0.7m3
Later, the model was renewed with a focus on more speed and power while maintaining the existing soft feel that New Avance offered. In order to cope with aggressive digging, it came with active mode and one touch power up mode that gave it the ability to switch into full play when needed.
Also, to meet the expanded demand for rental, Komatsu introduced a rental package that made maintenance easy.
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.
