DEMOLITION ATTACHMENTS

The Extension Kit can be configured in several ways with an elbow and beams, allowing the operator to perform Hydrodemolition in hard to-reach areas.

New Aquajet attachments streamline concrete repairs

Aquajet Systems AB is a pre-eminent name in the realm of hydrodemolition in South Africa. Locally the Aqua Cutter 710V hydrodemolition robot, distributed through Total Blasting, offers something unique. But the 710V’s big brother, the Aquajet 750V has been introduced to the market this year, and it’s time to see how this machine’s range of attachments allows it to be top of the class.

W hile South Africa most often must wait for the latest equipment to become available after its launch, the Aquajet Systems ABs available locally aren’t by any means dated. Since launching in 2017 the 710V is thoughtfully equipped with Aquajet’s signature ceramic nozzles which offer an extended lifespan—up to 79 percent more durable than the typical steel alternatives. Weighing in at 2,300 kilograms, the Aqua Cutter 710V harnesses the power of water jets ranging from 1,000 to 2,750 bar to remove up to 1 cubic metre of concrete per hour. Contractors have the flexibility to adjust the robot’s stroke for precise depth control of cuts and can vary the water pressure to suit the task at hand—be it clearing away weakened concrete or reducing robust concrete to a predetermined depth. Under the hood, the 710V houses a robust 18-kW diesel engine. For environments where diesel engines are not permissible,

on steel bridges, roadways, pipes, tunnels and more. The Hybrid Kit 3.0 converts the diesel powered 750V to electric when diesel cannot be used due to noise or emission requirements. “After a successful 750V launch, we wanted to fine-tune accessories that give our customers even more ways to use the robot,” said Roger Simonsson, Aquajet CEO. “There is a lot of concrete around the world that needs repair. The 750V provides a way to efficiently remove it, and these accessories increase where the robot can go and the types of removal that are achievable.” New configurations The Extension Kit can be configured several ways with an elbow and beams, allowing the operator to perform Hydrodemolition in awkward, hard-to-reach areas. During a bridge repair, for example, the Extension Kit allows the 750V to work from the bridge deck and reach over the barrier without

contractors can augment the robot with the Aquajet Hybrid Kit. This attachment enables electric operation and intelligently disengages the onboard diesel engine when necessary. The 710V robot is also compatible with Aquajet Systems’ 7-metre Power Packs, which house a high-pressure Hammelmann pump, a hefty diesel engine, and a control system, complete with a convenient storage section for the robot. The 710V is also fully compatible with the comprehensive range of accessories from Aquajet Systems, including rotolances, circular power heads, spines, and frames. The Aqua Cutter 750V While the 710V remains a solid workhorse, last month Aquajet unveiled an Extension Kit, Rotolance and Hybrid Kit optimised for its latest machine, the Aqua Cutter 750V. The Extension Kit increases the 750V’s reach for applications, such as bridges, berths, piers and wastewater plants, while the Rotolance excels at surface preparation
