Aquajet Introduces Powerful Aqua Cutter 710V for Heavy-Duty Concrete Removal
Aquajet Systems 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 ft (7m). The 710V comes equipped with Aquajet’s hallmark ceramic nozzles that last as much as 79% 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. Aquajet will highlight the Aqua Cutter 710V, along with other innovations, at booth F101901 during Conexpo-Con/Agg, March 10-14, 2020, in Las Vegas.
The 5,070-pound (2,300-kilogram) Aqua Cutter 710V uses 14,500- to 40,000-psi (1,000 to 2,758 bar) water jets to remove as much as 35 ft3 (1 m3) 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.
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.
The 710V features a powerful 24-hp (18kW) diesel engine. Contractors can add an Aquajet Hybrid Kit, which easily attaches to a diesel-powered Aqua Cutter robot for electric operation in parking garages, inside buildings, or other constrained 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, which 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. The 710V robot fits into Aquajet Systems’ 23-ft (7m) 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-lb (2,430-kg) 710V XL is 23% 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 accessories, such as rotolances, circular power heads, spines, and frames.
