Aquajet Introduces Powerful Aqua Cutter 710V for Heavy-Duty Concrete Removal

Aquajet Systems AB, a global leader in hydrodemolition machine manufacturing, introduces its farthest-reaching unit, the Aqua Cutter 710V hydrodemolition robot. It’s the largest of its kind and offers exceptional horizontal, vertical and overhead reach — as high as 23 feet. The 710V comes equipped with Aquajet’s hallmark ceramic nozzles that last as much as 79 percent longer than standard steel versions. Its design makes it suitable for a wide variety of concrete removal tasks, such as renovation and bridge and road repair.

“We designed the Aqua Cutter 710V to give customers the ability to accomplish more work, even in hard to reach areas,” said Roger Simonsson, Aquajet Systems managing director. “The robot’s extended reach allows contractors to get at and remove concrete in areas other robots simply cannot.”

The 5,070-pound (2,300-kilogram) Aqua Cutter 710V uses 14,500- to 40,000-psi water jets to remove as much as 35 cubic feet (1 cubic meter) per hour of concrete. Contractors adjust the robot’s stroke to control the depth of cuts and vary the pressure of the water jet depending on whether they are removing loose, deteriorated concrete or lowering the sound concrete to a pre-determined depth. A valuable feature of hydrodemolition is that rebar is cleaned and descaled during the process, whereas alternative methods, such as pneumatic tools or milling machines, may damage the rebar or produce microfracturing in the remaining concrete.

Operators can control the 710V from a safe distance using the unit’s radio remote control, either
wirelessly or with a hard wire. The remote communicates with the robot’s wheeled power
control module.

Contractors use Aquajet’s unique cutting head, extended reach and its multi-axis 3D positioning
system to efficiently operate on all horizontal, vertical and overhead areas that would be difficult
to get at with other equipment. This includes straight up and down work, such as renovating
walls, shafts and furnaces. In addition, the 710V easily removes concrete in corners that would
be difficult to access with hand tools. Aquajet constructs the 710V’s steel mast in sections — an
innovative design that gives the operator freedom to raise the front power head as high as 23 feet (7 meters) — 10 feet (3 meters) higher than the Aqua Cutter 410V — without additional support.

The 710V features a powerful 18-kW diesel engine. Contractors can add an Aquajet Hybrid Kit,
which easily attaches to a diesel-powered Aqua Cutter robot for electric operation in applications
where diesel engines aren’t allowed, such as parking garages, inside buildings or in other urban
environments. The kit uses an intelligent system to automatically disengage the onboard diesel
engine.

Aqua Cutter robots feature unique ceramic nozzles specifically designed for demanding
hydrodemolition applications. The highly efficient nozzles last 300-350 hours, depending on the
water quality. Standard steel nozzles on competitive equipment typically have a lifetime of 20-40
hours.

All Aqua Cutter robots feature Aquajet Systems’ patented Equal Distance System. EDS keeps a
preset distance from the nozzle to the concrete surface, regardless of the angle of the water jet,
allowing for maximum efficiency and productivity. Systems without EDS lose as much as 20
percent of the power before the water hits the concrete, greatly reducing productivity and
increasing waste.

The 710V robot fits into Aquajet Systems’ 23-foot (7-meter) Power Packs. The large metal
containers include a high pressure Hammelmann pump, large capacity diesel engine and control
system, with a convenient storage area for the robot.

The hydrodemolition robot features unrivaled ease of access for all maintenance, allowing for
minimal downtime. The unique gullwing hood and foldable back cover of the Aqua Cutter robot
offers total access for both daily maintenance, such as checking oil levels, as well as periodic
service jobs, such as oil and filter changes.

The robot also comes in a larger version, the Aqua Cutter 710V XL. The 5,357-pound (2,430-
kilogram) 710V XL is 23 percent larger than the 710V, allowing for lower overall ground
pressure and the ability to handle more reaction force.

The 710V and 710V XL are both compatible with Aquajet Systems’ line of accessories, such as
rotolances and circular power heads, as well as spines and frames.
