buildup removal

DrumJet-HP

Robotic concrete build-up removal system for concrete mixertrucks to remove sticked concrete, mortar and hardened, buildup from the mixerdrum blades and drumwall.

The DrumJet-HP system is a semi-automatic high-pressure concrete removal system, operated by a certified operator. The system replaces human entry for the manual concrete removal job with jackhammer in this named confined space.

History

Main goal for development of the DrumJet-HP is to prevent people entering the confined space of the mixerdrum. The system is developed as a curative method for robotic concrete buildup removal. The first generation DrumJet-HP machines are relay steered, actuating solenoid direct acting valves for hydraulic machine functions. The system is operated through a wireless remote control offering the operator to stay safe during operations.

Present, 2025

While the first generation DrumJet-HP was developed as a curative method, the third generation DrumJet-HP was a PLC steered machine. the DrumJet-HP G3 was in theory also offering more operator friendly solutions because of the PLC steering. The PLC steering actuates proportional valves and direct acting valves for all DrumJet-HP functions. All functions of the machine could be operated from the wireless remote controll which is equipped with a screen for easy function checks. The 2020 G3 machines were equipped with diesel engines complying with the latest exhaust requirements Tier4 Final (US) / Stage5 (Europe). Nevertheless 2025, the latest “DrumJet-HP model 2025” has made its entry into the market. The best and most robust system that has been developed for robotic mixerdrum concrete buildup removal until today.
