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.
Loaded with "Sigma Dozer", the new concept blade that improved dosing, this model had productivity that was 15% higher than the previous models. The automatic speed changing power line with auto lock up controller system had superb power transmission and reduced fuel consumption by 10%. This model was also equipped with an engine that utilized the newest engine technology "ecit3". With all those updates, the fuel efficiency was improved by 20% compared to the previous models.
It also adopted the original undercarriage "K-Bogie" that had proved to work well for large models, achieving excellent traction and driving comfort. The remote control system "KOMTRAX" comes as a part of the standard equipment.
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.
