FTS, 4 general contractors/Development of remote control technology for spraying concrete in mountain tunnels

You can spray safely and comfortably in the control room away from the face (provided by FTS)
FTS (Chuo-ku, Tokyo, President: Hiroyuki Kimura), which develops and sells construction machinery, and four general contractors, including Shimizu Corporation, have developed the "Hercules" system, which remotely controls concrete sprayers in mountain tunnels. Spraying can be done safely and comfortably in a remote control room away from the face. In the future, the five companies will work to improve functions such as enhanced guidance functions and automatic nozzle control, aiming for full automation of work near the face.
Hercules consists of a remote control room, a video and control signal transmission system, and a machine control system. In the remote control room, there is an operation cockpit with control levers and foot pedals. to operate. You can work in a comfortable environment without the risk of dust or heatstroke, and excellent workmanship control increases productivity.
A base station was installed on the power trolley of the underground equipment in order to transmit the image of the spraying machine. Between the base station and the main body of the spray gun, we constructed a system that wirelessly transmits images and machine operation information signals via a high-speed wireless LAN. The base station and the remote control room are connected by wire, and by extending the communication cable, the remote control room can be installed not only inside the mine but also outside.
The airframe control system consists of an operation control panel that remotely controls operations such as starting the engine, running, and stopping using operation signals from the remote control room, and a video control panel that wirelessly transmits video signals from the airframe camera to the base station. Configure.
Hercules was jointly developed by five companies: ▽FTS, Shimizu Corporation, Toda Corporation, Nishimatsu Corporation, and Maeda Corporation. Utilizes Nishimatsu Construction's remote control technology. In the "Fukuoka No. 201 Tsukuho Tunnel New Construction" (ordered by the Kyushu Regional Development Bureau, Ministry of Land, Infrastructure, Transport and Tourism), a series of preparation work such as running the spraying aircraft and setting it to the face, and spraying work were remotely controlled in the tunnel. Operate wirelessly from inside the room. We confirmed the effects of the introduction of the system, such as improved safety and improved work environment.
