The IT revolution had a tremendous influence on the technology of construction equipment as well. The satellite operation management system was developed during the 90's as a method to supervise and manage equipment from a remote distance, and became an industry standard during this era.
Take off and low speed (1st gear) were supported by the powerful hydraulic drive, and mid and high speed (2nd and 3rd gear) were supported by direct drive. After the model change, it achieved the world's first high speed running of 50kmph. In addition to the standard operation modes, it adopted the new heavy excavation mode supported by the engine/pump total control.

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.
