Power Cutter – Milling Robots & Control Panels

The Power CUTTER series has garnered an excellent reputation in the area of self-propelled robots in recent years.

IST Power Cutters

The Power CUTTER brand name speaks for itself. Continued further development (e.g. in the observation camera and cable routeing) has produced considerable improvements.


A complete robot unit for Ø 150 to Ø 400 mm diameter pipes (i.e. the PC 150), including a 75-metre hose reel, controls and controller interface can easily be loaded into a medium-sized estate car (or station wagon).


Furthermore, an Power CUTTER 150 can be transported inside different vehicles instead of requiring a separate carrier truck to always be brought along. Therefore, the cutter can be taken out one day with the spot repair team, the next day with the liner group to carry out preparations for the rehabilitation and the following day to, for example, prepare joints for a grouting repair.

Mechanical features of the system

No supply lines on the body!

  • No airhose of the airmotor.

  • No waterhose for the camera cleaning device.

  • No hydraulic lines on the body.

  • No cables for the camera on thge body.

⇒ This design allows an endless circling without stop.

⇒ No damages on supply lines, hoses, airmotor and camera.

Electronical features of the system

Electronical Monitoring

  • Sonsory monitoring of the arm.

  • Pressure sensor in the crawler.

  • Temperature sensor in the crawler.

  • Humidity sensor in the crawler.

  • Integrated inclination sensor.



  • Sure data transfer between the controller and the connected components.

  • CAN-Bus allows a modular structure.

  • Easy integration of additional components in the system.



  • Display the angle of the arm.

  • Display pressure, temperature and humidity in the crawler.

  • Display the inclination.

Power CUTTER 200

The highly versatile milling robot, way ahead of its time.

This robot has functional design with no supply lines to the apparatus; the endless circles of the robot’s arm are without end stop. In addition, the PC 200 visualises the arm position and has a CAN-Bus control.

  • No external supply lines on robot

  • Sensor monitoring

  • Remote maintenance module

  • Speed control

  • Proportional control with saving of milling position and arm setting.
