(1994)

Komatsu Bulldozer D155AX

This was the first construction equipment in the world that was equipped with the automatic continuously variable transmission.

Arranging the mechanical transmission and hydraulic transmission (hydraulic pump and motor) in a line, it had both high efficiency of a direct drive vehicle and good the operability/continuously variable transmission of a hydraulic transmission. The automatic continuously variable transmission reduced operators' fatigue while working.

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.
