Encompassing an expansive 490,000-square-meter site, the Tsuchiura Works manufactures a complete range of construction equipment including small- and medium-sized hydraulic excavators. The Tsuchiura Works also houses a hydraulic machinery plant producing pumps, motors and other hydraulic machines, as well as a parts division and various laboratories. It also hosts our Technical Research Center, which conducts diverse kinds of basic and applied research. In all areas of its operations, from R&D to design, production and inspection, the Tsuchiura Works brings to bear the most advanced technologies in a constant effort to raise its construction machinery, factory automation and other products to ever higher levels of performance and quality.

Occupying a 180,000-square-meter site not far from the Tsuchiura Works, the Kasumigaura Works is a high-tech production line designed to be operated by minimal staff. This is made possible by the use of an array of computer-controlled devices including material-handling robots, NC machine tools, unmanned conveyance carts and automated warehouse facilities. The plant manufactures key components of construction machinery, such as reduction gears, swing wheels and rollers, and supplies them to assembly lines at the Tsuchiura Works and to our overseas production bases.

Occupying a 210,000-square-meter site as the third plant established following the Kasumigaura Works, the Hitachinaka Works manufactures large and ultra-large hydraulic excavators and key components for dump trucks used in applications such as mining, as well as wheel loaders, crawler cranes and other machinery, and supplies them to assembly lines at the Tsuchiura Works, TCM Ryugasaki factory and to our overseas production bases.

Occupying a 180,000-square-meter site located within Ibaraki Port (Hitachinaka Port), which is one of Japan’s major ports, the Hitachinaka-Rinko Works manufactures large and ultra-large hydraulic excavators, as well as dump trucks used in applications such as mining, and supplies these products to respective countries worldwide by taking the advantage of its convenient location adjacent to the port.
