Our Business Departments
Power Transmission Department
Since its establishment in 1971, Sasagawa Densetsu, the predecessor of our company, has been engaged in the construction of transmission line towers to supply electricity, which is very closely related to our daily lives.We are committed to supplying electricity safely to our customers and helping them to spend their days with peace of mind by quickly responding to natural disasters such as earthquakes and typhoons, and restoring power outages. Of course, we also give full consideration to the safety of our staff, and each member of our team is striving to further improve their skills.
The construction of transmission line towers can be roughly divided into civil engineering work, tower assembly work, and overhead line work.Civil engineering work is used to build the foundation for the costruction, tower assembly work is used to build the tower to pass the power lines, and overhead line work is used to string the power lines to conduct electricity. Our company has an environment that allows us to perform all construction work, and our experienced staff quickly and reliably builds electrical paths from scratch. In the future, electric power will be needed more than ever. We will work together as a team and strive to fulfill our role, advancing as experts in the field of linemen.
Telecommunications Business Department
TCA, the predecessor of our company, has been engaged in the installation, design, construction, and management of cellular radio base stations in the Kanto and Tohoku areas. We are performing our daily operations by utilizing our abundant knowledge and the technology we have cultivated over the years. We respond quickly to requests for small installations, annexations, and expansions, as well as large-scale new installations, and indoor installations in subways and large buildings. As new technological innovations are introduced in the future, we will continue to make daily efforts and devote ourselves as experts in the field of telecommunications engineer.
Wireless Base Station Construction
We provide one-stop services for cell phone base station installation from negotiation to construction management, regardless of the size of the project.
We are flexible and work with expertize.
Land stations (towers)Construction of steel towers and installation / replacement of attached radio equipment and antennas
Building StationsInstallation and replacement of new radios and antennas on building rooftops and indoor commercial facilities
Land station (concrete pillar)Construction of concrete pillars and installation / replacement of attached radios and antennas
Maintenance and inspection of wireless base stations
We provide inspection and maintenance services for cellular radio base stations at the request of businesses. In addition to normal inspections and maintenance, we also provide infrastructure maintenance for quick and early restoration in the event of a disaster, based on our experience from the Great East Japan Earthquake.
MaintenanceMaintenance of existing stations
Periodic InspectionPeriodic inspections of installed stations are performed throughout the year.
Environment Business Department
TCA, the predecessor of our company, has been constructing and maintaining observation towers for the construction of wind power plants widely from the Pacific coast of Kanto to the Sea of Japan coast of Tohoku. Since the observation towers are more than 60 meters high, they require special and advanced technology, and with the zero-carbon declaration in October 2020, the wind power generation business is increasingly in the spotlight, and this division is sure to grow in the future.
