“Aquajet is at the frontline of product development, giving customers a variety of tools to ensure maximum utilisation of their Aqua Cutters and enable the benefits of hydrodemolition in nearly every application,” said Roger Simonsson, Aquajet managing director. “The Super Lance System is a well thought out solution to enhance our already innovative hydrodemolition robots.” The system was recently exhibited at World of Concrete in Las Vegas.

Each element of the Super Lance System serves an important purpose to help contractors problem solve. Elbows help operators navigate tricky obstacles while lance extensions can be stacked to create the correct length required for the application. One option for the system is the dual/triple nozzle head that is compatible with all lances and lance extensions, elbows and ‘Rotolances’. The dual and triple nozzle heads split the waterjet to impact the concrete at multiple points, allowing it to cover more surface area in each pass. This allows an operator who is working with a very powerful high pressure pump, for example, to effectively execute a shallower removal (25.4mm to 50.8mm). 

Without the dual/triple nozzle, a contractor with a 370kW+ power pump would typically maximise speed and oscillation to avoid cutting too deeply which can compromise the quality of the result.  By diffusing the water jet, the operator can decrease the machine’s speed while retaining a shallow cut. When the Rotolance, Aquajet’s surface preparation tool, is configured with the dual and triple nozzle heads, it provides rotational hydrodemolition for effective shallow removals from 10mm to 50mm. 

The dual and triple nozzles feature Aquajet’s ‘LFD’ (Laminar Flow Director) concept, said to make the setup as efficient as using two or three separate lances. When water flow changes direction or passes through diameter changes, it creates turbulence, making the water less effective. The LFD design avoids this by eliminating all forms of turbulence before water enters the nozzles. Dual and triple nozzle heads work with lances, lance extensions and Rotolances. Another highlight of the Super Lance System is the cross nozzle configuration option for all Rotolance models. The cross nozzle intersects two water jets at a certain depth, cancelling each other out to achieve a very precise cut. It’s available with 30mm, 60mm and 100mm removal depths as standard.

The Super Lance System is based on Aquajet’s standardised ‘Aqua Cone’ that makes several configurations possible. It features unique elbows compatible with all hose adapters that can be stacked to go around obstacles as needed. It also offers nozzle types, lances, lance extensions, and the dual nozzle head and triple nozzle head to provide contractors with greater versatility. The Super Lance System is compatible with Aquajet’s ceramic nozzles engineered for extreme durability. With an expected lifetime of 350h, Aquajet’s ceramic nozzles are designed to provide industry leading longevity, cost savings and productivity to maximise efficiency on the toughest jobs.
