Shotcrete Sprayer Remote Control



Underground mines operating in hard rock environments


Keeping mine operators safe is a challenge in any underground mining environment. One of the actions taken to accomplish this is solidifying the tunnel walls to prevent rocks from falling and causing injury to workers. Additionally, the roof may lose support if the walls slide, increasing the risk to those working inside the tunnels. Securing the walls is done by spraying concrete cement onto the walls at a high pressure and velocity. The splash and fumes created by the pressurized cement hitting the walls require that the operator stands as far as possible behind the machine.


A remote control system is used to operate the shotcrete sprayer machine from a safe distance. The system controls the boom articulation, the nozzle angle and the pressure at which the concrete is sprayed onto the walls.

  • Battery can last an entire shift before it needs to be charged.
  • Configurable with frequencies and identification codes such that many systems can operate in the same area without interference.
  • The rugged construction of the machine control unit ensures reliable operations.
