Aquajet takes hydrodemolition to next level with 750V Aqua Cutter

750V features the next generation Evolution 3.0 Control System that automatically calculates optimal settings for lance motion for greater precision and efficiency

Aquajet has introduced its latest hydrodemolition robot, the Aqua Cutter 750V.

Aquajet, a leader in the design and manufacturing of hydrodemolition technology, said the new model launches Aquajet’s patented Infinity oscillation that moves the water jet in an infinity – or figure 8 – pattern, removing more concrete in a single pass while reducing shadowing, eliminating the risk of pipe holes and providing an ideal bonding surface.

The 750V also features the next generation Evolution 3.0 Control System that includes new functions, including the ability to automatically calculate optimal settings for lance motion for greater precision and efficiency, according to the company.

Like all Aqua Cutter Robots, the 750V cleans and descales rebar without causing microfracturing. It also maintains horizontal, vertical and overhead reach, making it suitable for a wide variety of concrete removal tasks, such as renovation and bridge and road repair.

“Aquajet has always been at the forefront of hydrodemolition innovation,” said Roger Simonsson, Aquajet managing director. “Infinity oscillation is the next technological evolution, and it is changing how hydrodemolition contractors think about productivity.”

He continued, “In the coming years, we will see it replacing rotating lances and similar tools to become the new industry standard. With the productivity gains realized during customer testing, the Aqua Cutter 750V is a significant advancement for hydrodemolition.”

The constant lance motion of the infinity oscillation pattern reduces the need to follow up with hand lancing. The consistent motion also increases the digging effect and virtually eliminates pipe holes, resulting in a superior bonding surface and increased productivity. Another benefit is the constant, low noise that is less disruptive in urban areas and other noise-sensitive environments, a release from Aquajet said.

The Aqua Cutter 750V shares several similarities with Aquajet’s Ergo System. The infinity power head has Ergo-style spring-tensioned rollers and quick connection to the roller beam. It also uses absolute sensors, which means it automatically adjusts at the touch of a button. With a larger roller width and a new triangulated base frame for improved stability, the infinity power head contributes to precision while improving the hydrodemolition result.

As part of the new design, the Aqua Cutter 750V includes an upgraded version of the Evolution Control System. First released in 2004, this control system still features Aquajet’s patented Equal Distance System (EDS) as well as the ability to cut shapes and remove concrete at different depths in the same pass.

The 750V is compatible with Aquajet’s line of accessories, including the rotolance, circular power head and Aqua spine. It is also compatible with Aquajet’s Ecosilence high-pressure pump that supplies the water to run the machine and provides a cost-effective option for transport and storage.
