News from the hydrodemolition world

Published 2/12, 2020 at 14:08

The two Swedish manufacturers of hydrodemolition machinery and equipment have continued their efforts to raise the profile of their concrete removal technology.

Aquajet has announced that its new ‘Aqua Cutter’ 410V hydrodemolition robot is now an even safer and more efficient alternative to manual industrial cleaning methods. The model combines the compact size of the Aqua Cutter 410A with the innovative mast system of the Aqua Cutter 710V  for unrivalled performance when working in tight spaces such as boilers, tanks, pipes and other industrial containers and conduits. With a free standing reach of up to 4m, the 410V gives operators the ability to work horizontally, vertically or overhead, while the remote operation keeps them out of harm’s way during hazardous cleaning applications. The 410V’s design also makes it suitable for a wide variety of industrial cleaning tasks in oil, gas, petrochemical, refractory, nuclear and other industries where it can increase efficiency up to 80%.

 The 1,250kg Aqua Cutter 410V uses 1,000 to 2,750bar (approx.) water jets and a range of attachments for efficient concrete removal or surface preparation. Users are also able to adjust the robot’s stroke to control removal depth and vary water pressure to match the application, increasing precision and efficiency over hand lances and other manual methods. This can significantly increase efficiency for applications such as tank and large diameter pipe cleaning, reducing the time and personnel required while still producing high quality results. The 410V features electric power and is compatible with Aquajet’s line of accessories, such as the ‘LT’ extension kit and ‘Rotolance 2500 LT’, as well as spines and frames. 

Another choice available for users is the Aqua Cutter 410V ‘Tunnel Kit’, specifically designed for cleaning and surface preparation in applications such as steel or concrete pipes and tunnels up to 3m in diameter. The kit uses a rotolance and features automatic detection and the ability to adjust the distance to the tunnel surface. This makes it very easy to operate in uneven tunnel shapes or oval tunnels.

 

Ecosilence 3.0 

Aquajet has also recently introduced the new ‘Aqua Power Pack Ecosilence 3.0’ that reduces noise and allows for a more compact jobsite, while enhancing environmental stewardship and lowering overall operating costs. The new Ecosilence features integrated auto start/stop technology that improves fuel consumption, which saves as much as 25l/day of fuel for a smaller carbon footprint.  The re-engineered Ecosilence is also more compact with the entire self-contained system now fitting in a standard 6m shipping container. It also produces less noise while in operation, making it ideal for use in urban areas with limited space and strict noise restrictions. 

The new unit also has dramatically improved pumping pressure, operating as high as 3,000bar and providing ample power for hydrodemolition applications such as concrete renovation and road and bridge repair. Like all previous Aqua Power Packs, the Ecosilence 3.0 is easy to transport and set up, measuring 6.1m x 2.4m x 2.6m while maintaining innovative sound absorbing design features.  The latter includes insulated walls and doors, as well as seals on all doors and hatches. Despite the shorter overall length, the container still provides ample storage for the company’s Aqua Cutter robots, accessories and tools. Additional options are available to customise this work area, such as a built-in workbench with a vice that provides a space for jobsite maintenance and a place to store spare parts. The Ecosilence 3.0 is available in several pressure and flow combinations, allowing operators to scale equipment to meet their specific needs.

Conjet 

Conjet AB has recently launched a new graphical user interface for all ‘7-series’ robots. The new interface has been developed for working at a safe distance through the use of an interface on the robot or on the identical remote control box. The interface consists of two separate parts, one focused on operation and the other focused on service. The settings are easy to reach with just a push of a button with the interface also giving the operator instant feedback on the set parameter. Another important update is the ability to manoeuvre between controls and options using a rotary encoder. 

The display located on the robot is a 178mm colour screen with an 800 x 480 pixel resolution which will be available on all Conjet 7-series robots. The colour display on the remote control box is a 109mm LCD, 480 x 272 pixels, with 2mm thick protective Gorilla glass which utilises the surrounding light to give a sharp and clear image in more difficult environments such as bright sunlight. With this display the user is able to steer and control every aspect of hydrodemolition at a safe distance, resulting in no need for the operator to be close to the robot during operation. Should a fault arise, a comprehensive trouble shooting guide is available to the operator, with all existing robots in the 7-series being so  equipped with the new interface.

Applications wise, Conjet has also moved away to a degree from only using the word ‘hydrodemolition’ to define its services and offering. Instead the company has released a new concept termed, ‘Automated Concrete Removal’, which covers  more uses in terms of applications where high pressure water can used as an efficient concrete removal method.

Recently Conjet participated in the virtual trade show DEMCON hightlighting the latest novelities from Conjet including the new interphase. Lars-Göran Nilsson, one of the founder and and former owners of the company explain online the background of the company. Conjet’s news CEO Robert Kreicberg talked about Conjet today and in what direction the company is aiming. Service manager Conny Tångring described the advantages with the new graphical user interface on the Conjet 7-series.
