Aquajet Super Lance System for Concrete Removal

The system includes multiple parts — such as elbows, lance extensions and different nozzle options — to give operators control over the concrete removal depth.

Aquajet offers the Super Lance System for concrete removal, adding versatility to its line of Aqua Cutters by allowing for several configurations. The system includes multiple parts — such as elbows, lance extensions and different nozzle options — to give operators control over the concrete removal depth. 

Aquajet is at the frontline of product development, giving customers a variety of tools to ensure maximum utilization 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.” 

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 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 powerful high-pressure pump, for example, to execute a shallower removal (1 to 2 in. or 25.4 to 50.8 mm). Without the dual-triple nozzle, a contractor with a 500+ horsepower pump would typically maximize speed and oscillation to avoid cutting too deeply.  

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 shallow removals from 0.4 to 2 in. or 10 to 50 mm.  

The dual and triple nozzles feature Aquajet’s unique LFD (Laminar Flow Director) concept. The LFD design avoids turbulence from passing through diameter changes or directional changes in water flow by eliminating all forms of turbulence before water enters the nozzles. Dual and triple nozzle heads work with lances, lance extensions and Rotolances.

Another feature 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, canceling each other out. It’s available with 30-, 60- and 100-mm (about 1-, 2- and 4-in.) removal depths as standard. 

The Super Lance System is based on Aquajet’s standardized Aqua Cone that makes several configurations possible. It features elbows compatible with 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 versatility. 

 With an expected lifetime of 350 hours, the Super Lance System is compatible with Aquajet’s ceramic nozzles engineered for extreme durability.
