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.
This was a full model from the large self-propelled crusher, BR550JG.
It met the latest exhaust standard in Japan/US/Europe, and was equipped with Komatsu's original automatic hydraulic jaw crusher that had gained a good reputation with BR380G, a self-propelled crusher of the 30-ton class.
It could protect the crusher by employing the hydraulic lock cylinder, even if it bit a foreign substance such as metal. Under such circumstance, it could easily extend the space to the maximum, minimizing the downtime.
There were other construction machines built by Komatsu over the years. We can see how the various designs mirrored different eras if we look at them set against the flow of history.
