HCM’s Manufacturing Bases

HCM’s construction machinery is manufactured based on a fully integrated, comprehensive production system centering on the Tsuchiura Works located near the city of Tsukuba in Ibaraki Prefecture. The construction machinery produced here operates in Japan and respective countries worldwide in various areas ranging from residential and building construction, plant construction, urban development, infrastructure maintenance and mining resources, including coal and minerals, to the modernization of telecommunications and transportation networks and the creation of more greener and more environment-friendly living environments.

Tsuchiura Works

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.

Kasumigaura Works

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.
