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.
Equipped with the original transmission, HST (Hydro Static Transmission) and the 3-speed HST motor that let the operator choose from 3 different speeds. This model had a very high soil preparation performance. Adopting the new palm mono lever (PCCS: Palm Command Control System) that was based on human engineering design, it significantly improved detailed operability.
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.
