Aquajet Offers Two New Products for Concrete Removal Versatility

Aquajet recently introduced two new products to provide more flexibility in hydrodemolition. The Super Lance System increases the versatility of the company’s Aqua Cutters by allowing for several configurations. The new Extender accessory is a flexible addition to the Aqua Cutter 750V that adapts to surfaces with height variations in overhead, below-grade, or constrained-space applications.
Super Lance System
The Super Lance System includes multiple parts to give operators more control over the concrete removal depth. In addition, elbows help operators navigate obstacles while lance extensions can be stacked to create the correct length required for the application.

The system’s dual/triple nozzle head is compatible with all lances and lance extensions, elbows, and Rotolances (Aquajet’s surface preparation tool). The dual and triple nozzle heads split the water jet to impact the concrete at multiple points, allowing it to cover more surface area in each pass. This allows an operator working with a very powerful, high-pressure pump, for example, to effectively execute a shallower removal of 1 to 2 inches.

Without the dual/triple nozzle, a contractor with a 500-plus horsepower pump would typically maximize speed and oscillation to avoid cutting too deeply, but this 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 is configured with the dual and triple nozzle heads, it provides rotational hydrodemolition for effective shallow removals from 0.4 to 2 inches.

The dual and triple nozzles feature Aquajet’s unique Laminar Flow Director (LFD) concept, making 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 turbulence before water enters the nozzles.

The Super Lance System also features a cross-nozzle configuration option for all Rotolance models. The cross nozzle intersects two water jets at a certain depth, canceling each other out to achieve a precise cut. It’s available with 30-, 60- and 100-millimeter (about 1-, 2- and 4-inch) removal depths as standard.

The Super Lance System is based on Aquajet’s standardized Aqua Cone that makes several configurations possible and is compatible with Aquajet’s ceramic nozzles, which have an expected lifetime of 350 hours.

Extender Accessory
Aquajet’s new Extender accessory comes with a hydraulic hose package that allows easy mounting on the Aqua Cutter 750V robot, with no need for additional hydraulics or other equipment.

“Projects sometimes require concrete removal in tricky spots or angles,” said Roger Simonsson, Aquajet Managing Director. “We designed this tool to offer optimal versatility and flexibility for those unique jobs.”

The accessory attaches to the Aqua Cutter’s tower to perform hydrodemolition on areas such as sloped roofs or roofs with varying heights up to 4 feet. Additionally, the Extender works in below-grade applications such as ditches or canals where the concrete surface requiring removal lies up to 3.3 feet below grade level.

The Extender also enhances side operations between beams on structures like bridges and parking garages, extending up to 8.2 feet to either side. The extended capability for sideways applications requires the smaller protection cover over the power head. This function is beneficial in confined or tight spaces.
