As use of ICT for construction equipment became more common, things like crewless dump trucks, IT execution, and KOMTRAX were further developed. Hybrid equipment that decreased both fuel consumption and carbon dioxide emission was introduced and marked a new generation of construction machines.
NOx and PM emissions are drastically reduced, by adopting a new exhaust gas aftertreatment system (※1) for construction equipment. Furthermore, the advanced hybrid system with further improved durability and the new engine, as well as the total electronic control of hydraulic equipment, reduce fuel consumption.
The latest iMC is installed in this equipment. The latest KOMTRAX (Komatsu Machine Operation Tracking System) enables management of the vehicle operation information for each operator, as well as confirming the remaining amount of AdBlue®(*1) required for selective catalytic reduction (SCR) of the exhaust gas aftertreatment system.
In order to improve safety, KomVision (ambient monitoring system for general construction machinery), an automatic lock function for the lock lever, the secondary engine stop switch, and large handrails to prevent falling are newly adopted.

Hydraulic excavator
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.
