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.
Output of the 872PS was the best in its class. This model had excellent workability with the high power engine that provided low fuel consumption. With a new undercarriage, it improved the essential performance of a bulldozers duty such as pulling and leveling. The new control lever improved operability, while the large cab and air conditioner improved comfort and productivity.
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.
