Aquajet Systems to launch Ergo Spine at World of Concrete 2019

Aquajet Systems AB, the hydrodemolition division of Brokk AB, will launch the Ergo Spine attachment for its new Ergo System hydrodemolition machine in the United States at World of Concrete 2019, booth C4249. The Spine wields four times the water reaction force of hand lances, giving contractors a more powerful and safer alternative.

“This innovative attachment couples with the convenience and portability of the Ergo System to deliver a lightweight, yet formidable, hydrodemolition solution,” said Roger Simonsson, Aquajet Systems managing director. “Its powerful water jets efficiently take on concrete removal and repair in some of the most challenging spaces to work, opening up the productivity of robotic hydrodemolition to nearly anybody in any location.” The Spine includes an Aquajet power head attached with a single bolt to a roller beam, which is connected to a spine roller mounted on a spine rail. Depending on the configuration, the setup may be supported by standard support legs, or the spine rail may be attached directly to a surface. 

Aquajet manufactures the roller beam with a lightweight aluminium core coupled with a steel gear rack and guide rails. Beam sections are mounted together with a single bolt. The Ergo Spine roller features a low weight, high strength skeleton base with a wheel setup that divides forces for the ability to handle high reaction forces. The spine rail is fabricated with high strength aluminium, reducing its weight by half compared to steel. A 2m rail weighs just 22kg, and despite its lightweight properties, the rail handles the same reaction force as an entirely steel rail. The rail allows for quick connections with a single bolt for different brackets and tools. 

The Ergo Controller’s intelligent sensing controls automatically adjust and move the power head along the roller beam. Aquajet’s high pressure power pack, sold separately, provides water pressure and flow to the power head´s lance and nozzle, creating a reaction force up to 1000N. The Ergo power head can tilt at up to a 45o angle to attack the material efficiently and oscillates to get the best results for each job. As the Power Head moves along the Ergo Spine, it removes concrete in sections as small as 250mm, up to 2m, leaving the rebar clean and undamaged. An Ergo Spine with a power pack producing 2,800bar of pressure and 40l/min of water can remove an estimated 250mm3 of concrete per hour.

The Spine simplifies use as well as maintenance, and is highly portable. One person can carry and set up the unit and secure it with a single bolt. All connection points are marked in red, and all bolt sizes on the unit are the same, ensuring easy replacements. Further, the wheeled controller measures just 1m tall and 420mm wide, making it easy to get to the jobsite on a pallet, and then move effortlessly around the site.  

The Spine’s standard setup easily tackles concrete walls, floors and ceilings while the side setup delivers hydrodemolition power to narrow spaces.  

Aquajet Systems backs its full line of hydrodemolition robots and accessories with service after the sale as well as product training. Through its Aquajet Training Academy, contractors receive hands on instruction and resources to spur their hydrodemolition success.
