The direct drive twin motor system, on the other hand, is a patented system that makes it possible to distribute the force of the two rock cutter heads in different ways. The advantage is huge, since the power of the two drums is managed on the basis of the toughness of the material, and the vibrations transmitted to the excavator arm are absorbed.
Thus it is possible to cut various different kinds of material, from hard to less resistant, using the same drum cutter: simply choose between the low and the full set of picks to be used depending of the material to be cut.
So as the site manager of Pilotec confirms: “With the MB Crusher drum cutter, our customer saved money on costs and we finished the work in record time. So we are both very satisfied”.
