2000 OPEN

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.

A full model change was made to the mid size bulldozer well suited for land forming, leveling, and road constructions.

Komatsu's super slant nose design made the front engine hood area slimmer by placing the radiator in the rear. The innovative structure and body shape that broke stereotypes of bulldozers realized superb forward visibility. The floating cab, with the cab dumper mount, reduced operators' stress level by minimizing vibration while driving and experiencing shock from bumps and falls. Additionally, a swing type cooling fan (tip-up hydraulic drive fan) was used for the first time for bulldozers, which made maintenance and cleaning of the radiator much easier.

D51PX won the silver prize at IDEA (Industrial Design Excellence Awards) in the United States, receiving high praise for effective visualization of "super slant nose design". 

The same design was later featured with other bulldozers including D31, D37, D37 and D39.

Bulldozer 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.
