Conjet Jetframe

JETFRAME 137/157

Conjet’s Jetframe 137/157 ACR™ system allows selective removal of concrete in areas inaccessible to standard hydrodemolition robots. The Jetframe is remotely operated from up to 100 meters using any 7-Series Conjet ACR™ robot.

The Jetframe 137/157 consists of a rectangular frame supported on four legs that utilizes the feed beam and cradle from a Robot 327 or 557, or it can be purchased as a complete assembly. It can be bolted to the concrete surface being repaired or mounted on a tool carrier, such as a four-wheel drive forklift truck, sky lift platform or supported from winches.

The Jetframe 137/157 is specifically designed to remove concrete in the most difficult-to-reach places. It can also be quickly dismantled into components small and light enough to be carried by one man. It can operate on a variety of horizontal, vertical, and angled surfaces, including ceilings and underneath bridge decks.

Optimal for confined spaces:

  • Bridge pillars
  • Dam surfaces and spillways
  • Dry docks and quay docks


  • Handles the most inaccessible areas
  • Operates under water
  • Remotely controlled via any 7-Series robot
  • Rigid framework to maximize precision
  • Can operate at long distance from the control unit
  • Can be dismantled for easy transportation and handling
  • Customizable upon request for special projects

The rotor is suitable for cleaning applications or scarification of all surfaces. The rotor is normally equipped with 2-4 nozzles for concrete removal and up to 20 nozzles for surface preparation.

Fork Nozzle

The fork nozzle can replace the regular nozzle in the standard tool, providing a similar result to the rotor in terms of surface finish. It is mainly used for scarification.
