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.
In addition to K-Bogie, the original undercarriage that minimizes track slip, this model had eight lower rollers, which allowed better ground contact. Together with a low center of gravity, it yielded enormous traction power, driving stability, and effective leveling. Riding comfort was much improved by the combination of Cab Dumper Mount, K-Bogie, and the new swinging idler. It complies with the second regulation for emission gas of the EPA and EU.

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.
