The 2,756-pound (1,250-kilogram) Aqua Cutter 410V uses 15,000- to 40,000-psi water jets and a range of attachments for efficient concrete removal or surface preparation. Contractors can adjust the robot’s stroke to control removal depth and vary the water pressure to match the application, increasing precision, and efficiency over hand lances and other manual methods. This can significantly increase efficiency for applications such as tank and large-diameter pipe cleaning, reducing the time and personnel required while still producing high-quality results.

Roger Simonsson, Aquajet managing director, said:

“Industrial cleaning applications require flexibility. But with the models in the Aqua Cutter 410 series and Aquajet’s extensive range of attachments, contractors have the power and precision to tackle any application safely and still achieve unparalleled productivity. For example, we had a customer using a 410A that was able to reduce a routine pulp and paper scrubber cleaning from 30 hours to just five.”

The 410V also allows operation from a safe distance using the unit’s radio remote control, either wirelessly or with a hard wire. Contractors can remove the power control module from the tracked portion to reduce the crawler to one-third of its original size and create an even more compact robot. This provides the ability to drive the crawler into tight and inhospitable environments, such as small tunnels and flooded pipes, while the module remains connected via a cord.

And, thanks to superior lance control and Aquajet’s Equal Distance System (EDS), the 410V easily removes concrete and other materials in corners that would be difficult to access with hand tools. Its small size and light footprint allow operators to use the unit in confined areas — including passing through narrow passages, such as doorframes or operating from scaffolding — while retaining full mobility.

The 410V features electric power and is compatible with Aquajet’s line of accessories, such as the Extension Kit LT and Rotolance 2500 LT, as well as spines and frames. Contractors can also choose the Aqua Cutter 410V Tunnel Kit, specifically designed for cleaning and surface preparation in applications in steel or concrete pipes and tunnels up to 10 feet (3 meters) in diameter. The kit uses a rotolance and features automatic detection and the ability to adjust the distance to the tunnel surface. This makes it very easy to operate in uneven tunnel shapes or oval tunnels.

Roger Simonsson, Aquajet managing director, said:

“Safe and efficient wastewater handling is the number one concern for contractors, especially in bridge applications where even a minor spill not only threatens the environment but the contractor’s ability to work in that area. We’ve designed a trio of machines that, when used in combination, allows contractors to conquer road and bridge projects with power, precision and the complete certainty that wastewater is safe for release back into the environment or recirculation through the machine, reducing water requirements.”

With the 710V, operators can complete the work faster and with more precision than traditional methods. The 5,070-pound (2,300-kilogram) unit provides exceptional reach and unmatched productivity — up to 25 times faster compared to handheld pneumatic devices. It uses 14,500- to 40,000-psi water jets to remove as much as 35 cubic feet (1 cubic meter) per hour of concrete. Unlike other methods, Hydrodemolition cleans and descales rebar without damaging it or producing microfracturing in the surrounding concrete. The method also provides a superior bonding surface, which can extend the longevity of repairs by as much as three times, making it an ideal method for time- and budget-sensitive road and bridge repair projects.

For applications such as bridge deck repair and expansion joint replacement, the 710V combines power with industry-leading precision. Aquajet’s cutting-edge technology — including the Equal Distance System (EDS), ceramic nozzles and Evolution control system — provide unmatched productivity with high-quality results.

The 710V’s innovative mast design also gives operators unrivaled reach for applications such as columns, piers, abutments and parapets. The front powerhead can reach as high as 23 feet (7 meters) without additional support. Combined with Aquajet’s unique cutting head and multi-axis 3D positioning system, the unit provides versatile operation, easily removing concrete on horizontal, vertical and overhead surfaces that would be difficult to get at with other equipment.

The 710V is compatible with Aquajet’s line of accessories, such as extension kits, rotolances and circular power heads, as well as spines and frames, for increased versatility.

Powered by the Ecosilence 3.0 Power Pack, the 710V easily removes loose, deteriorated concrete or lowers the sound concrete to a pre-determined depth. Aquajet’s Ecosilence 3.0 consists of a 20-foot container that houses the engine and pump, offering reduced noise, low emissions and a cost-effective equipment transportation option, as well as secure storage for the robot and accessories when not in operation. A built-in workbench with a vise provides contractors a space for jobsite maintenance and a place to store spare parts, accessories and high-pressure hoses. The skid-mounted unit employs auto start/stop technology, like that found in many modern automobiles, which temporarily shuts down the engine when not in operation to reduce idling time by up to 50%. The Ecosilence 3.0 is available in several pressure and flow combinations, allowing operators to scale equipment to meet their specific needs.

With the EcoClear, contractors can leverage cutting-edge technology to meet even the strictest environmental standards. The system, contained in a compact, 20-foot container, lets contractors treat water, which can be scarce on some road and bridge applications, or safely release it back into the environment. The treatment system processes the wastewater generated through Hydrodemolition, neutralizing water pH and greatly reducing its turbidity. The EcoClear moves as much as 88 gpm, or about 5,283 gallons (20 cubic meters) per hour, through a series of treatment chambers that neutralize alkaline water to a pH of 6 to 9 and reduce turbidity to just 20-40 mg particles/liter, allowing contractors to treat wastewater in real time and maintain an environmentally sound jobsite. The entire process can be monitored and controlled with the RECO control system. This system records all historical data on outgoing water in a format that can be easily verified with third parties, such as project stakeholders or government agencies.

Simonsson said:

“To gain the advantage in road and bridge applications, contractors need to be able to do the job quickly and efficiently, but also to provide the documentation proving compliance with environmental regulations. For decades, our Aqua Cutters have been revolutionizing road repair applications. But with the addition of the EcoClear and the Ecosilence, contractors can really stand out in this highly competitive field.”
