Aquajet launches tunnel cleaning device

Swedish hydrodemolition machine manufacturer Aquajet has unveiled its latest piece of technology, the Aqua Centraliser.

Designed for use in roadbuilding, wastewater and industrial plant applications, the machine can be used to clean or remove concrete, paint, rust and coatings from the inside of tunnels and pipes.

Working in conjunction with the company’s Aqua Cutter hydrodemolition robots, the Aqua Centraliser is able to carry out these tasks along entire sections of tunnel, including inclined or vertical lengths.

An intriguing piece of hybrid equipment, the Centraliser uses elements of the company’s Aqua Spine system as its base (giving it a span of up to 6m), between a pair of triple support wheels. The machine also incorporates technology from Aquajet’s Circular Power Head – a 360° ring, that is generally used to wrap around concrete pillars.

In combination with an Aquajet power pack – which can provide up to over 2,750 bar – the company says the new machine offers contractors a winning combination of power and precision for the cleaning and removal of unwanted material.

Roger Simonsson, Aquajet Systems AB managing director, said, “Whether it’s a brand-new design or a reconfiguration of our current technology to allow for new applications, Aquajet is constantly at the drawing board to help our customers stay ahead of the curve. The Aqua Centralizer integrates key components of several of our existing designs to provide operators a new solution for working in pipes and tunnels more effectively than ever before.”
