Applying excavation technology cultivated to provide machines with a wider range of applications
In addition to the core products in excavating machinery, we manufacture various types of applied excavating machinery and peripheral machines. We also plan and propose a variety of machines to meet customers' needs in accordance with their work environment.
Development of a mining excavator capable of stably operating 2,000 meters under the sea
We participated in a project for mining seafloor hydrothermal deposits, which are expected to be a domestic source of marine mineral resources. MITSUI MIIKE MACHINERY developed a mining excavator that can operate stably and efficiently in deep sea at a depth of 2,000 meters. And this project succeeded in testing mining of seafloor hydrothermal deposits for the first time in the world.
Development of equipment for excavating hard rocks at sites where blasting is not possible
Since excavation by blasting is difficult at sites near a residential area, it is necessary to excavate by machine. However, excavating hard rocks takes time. Hence, Tasisei Corporation and MITSUI MIIKE MACHINERY jointly developed a machine that could excavate even hard rocks freely.Consequently, it became possible to efficiently perform excavation even in areas with hard rocks.
