Tunnel-Kreter SP 40Large shotcreting applications for tunnel construction can be handled with the self-propelled Tunnel-Kreter SP 40. The kinematics of its spraying arm and oscillating nozzle increase spraying speed. The 10-foot lance can be aligned parallel to the tunnel wall and it can be set to travel at variable speeds—automatically back and forth—so the operator can cover a 10-foot section of the tunnel by simply controlling the main boom.
