With a 6 level boom of 43m, this model had the highest lift above the ground. The high rigid hexagonal sectioned boom reduced deflection and stabilized operation. Its safety device automatically ceases movement when approaching dangerous areas, equipped with a function that slows the speed of turning and boom movements and softens shocks.
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.
