The Rotolance is a powerful tool for cleaning, light removal and preparatory work to roughening concrete surfaces. It removes rubber coatings, paint and various kinds of layers such as rust and plastic – without vibrations and dust pollution.
Our Rotolance comes in four versions and is compatible with all Aqua Cutter robots, as well as the Aqua Spine. All can be used to prepare concrete in various applications such as roads, bridges, harbours, sewerage pipes and industrial service in the petrochemical industries. But also for cleaning or removal of paint, rust and rubber from ship hulls, storage tanks and much more.
The Rotolance system helps to prevent injuries to the operator caused by hand held equipment. It also saves time and money, as it can operate around the clock. All movements are computer controlled in order to get perfect results every time.
Both the Aqua Cutter 710 and 750 comes with three Rotolance options, capable of handling water pressure up to 1000 or 2500 bar (14,500 or 36,300 psi). The Rotolance LT, compatible with the Aqua Cutter 410, handles pressure up to 2500 bar (36 300 psi).
Optimize precision and efficiency with our cutting-edge nozzle innovations. The Dual and Triple nozzle heads are perfect for shallower removals, as they disperse the waterjet impact across multiple points, effectively extending the covered area. Meanwhile, the Cross nozzle intersects two water jets at a specific depth, canceling each other out to achieve exceptionally precise cuts. Ideal for hydrodemolition applications requiring precise and shallow removal at a specific depth.
The Spraybar configuration, standard on all Rotolances, is particularly effective for surface treatment, providing a removal capacity of up to 10-15 mm. It excels in tasks such as paint and rust removal, making it a versatile choice for diverse hydrodemolition projects.
For those requiring rotational hydrodemolition capabilities, the Dual/Triple nozzle head is the ideal choice. 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. Also known as ”Hydromilling,” this configuration is specialized for shallow removal, covering a range from 10-50 mm. Its innovative design makes it a powerful tool for precision hydrodemolition projects.
Dual and triple nozzle heads work with lances, lance extensions and Rotolances.
The Cross nozzle configuration stands out for its unique approach, employing two intersecting jets that cancel each other out at a specified depth. This design ensures tailored removal to an
exact depth, with standard options available at 30 mm, 60 mm, and 100 mm. Depths in between can be achieved by adjusting the power head’s height.
There are two primary scenarios for using the Cross nozzle head:
Due to the jet’s canceling characteristics, careful consideration is necessary for robot settings to avoid excessive power cancellation and optimize performance.
