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.

With the full model change, its safety and eco aspects were improved further while keeping the basic concept of MR-2 that had an established reputation. It was compatible with the newest gas emission regulation and it was the first mini shovel equipped with KOMTRAX as part of its standard specs. This made it possible to show the position and working conditions of the machinery at anytime, and made maintenance easy and more efficient.

This model was also equipped with ROPS (Roll Over Protective Structures), a head guarded canopy, and a winding seatbelt, protecting an operator in case of roll over or falling objects. It also achieved all direction visibility by adopting a two-column canopy and a rear view mirror.

"X-shape truck frame" prevented soil from sticking, shortening the cleaning time during maintenance.

Hydraulic excavator OPEN

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.
