Aquajet, a global leader in the design and manufacture of innovative Hydrodemolition technology, introduces the new Aqua Rail System 3.0 designed to enhance the capabilities and flexibility of Hydrodemolition robots in challenging environments. The system centers around the upgraded Aqua Spine 3.0, an extendable rail system that attaches easily to any surface, providing a stable platform for the Power Head to move along during operation. The Ergo Climbers have also been upgraded to version 3.0, with new features that ensure seamless compatibility with the new system. To better support the Aqua Spine and Ergo Climbers, Aquajet created a customisable Support System, providing more flexibility and adjustable setups for different projects. This whole system is ideal for a variety of Hydrodemolition work and is compatible with the Aqua Cutter 750V, as well as the new Aqua Cutter 450A and 450V Hydrodemolition robots, and Ergo system. Recognizing that not all projects involve straightforward flatwork, this solution equips contractors with a highly adaptable, ready-to-use setup capable of tackling complex applications, such as tunnel, bridge, silo and dam wall repairs and refractory work.
Aquajet will highlight the new Aqua Rail System 3.0, along with other state-of-the-art Hydrodemolition solutions, at Stand A1.325 April 7-13 at bauma 2025.
“We noticed a pain point where contractors are still using hand lances for jobs that can be accomplished more quickly with a Hydrodemolition robot, given the right setup," said Roger Simonsson, managing director of Aquajet. "To make it easier to deploy Hydrodemolition robots in even the toughest environments, we upgraded both the Aqua Spine and Ergo Climbers, and developed a fully customizable Support System with adjustable legs, brackets and rotatable joints. This allows contractors to purchase a system tailored specifically to their project needs, ensuring the right configuration for each job."
The Aqua Spine 3.0 greatly expands range and flexibility for both on and offshore Hydrodemolition applications, excelling in both linear work — such as structure walls and power plants — and circular applications like tunnels and pillars. New passable mounts/brackets, support legs, adapter plates and feet make up the Aqua Spine, providing users the option to build longer setups when needed, rather than having to repeatedly move a shorter setup along the removal area. Passable mounts allow the Power Head to seamlessly move from section to section without the need to stop and reposition. The upgraded version is also lighter than the previous Spine and can handle 60% more load and 50% more torque.
The Aqua Spine 3.0 is compatible with the Circular Power Head and Aqua Centralizer, a ring mounted to the Aqua Spine base used for work on pipes or inside tunnels. The curved roller beam is compatible with both the Climber and Spine system and can be easily constructed into a complete circle. All parts of the Spine system are assembled with M16 or M20 bolts, allowing contractors to easily assemble and adjust with few tools.
The updated Ergo Climber 3.0 features several improvements, such as beam brackets with adjustable height and angle, adjustable clamping screws allowing it to attach and move along both standard and curved scaffolding pipes or roller beams and be configured as a complete circle for pillars and pipes. New passable brackets enable the Climbers to move the Ergo Power Head continuously along the scaffolding, making it possible to build infinitely long racks and increasing productivity without the need to stop and reposition.
“With this new Aqua Rail System, contractors can easily adjust the support legs to exact heights or angles, ensuring stability and optimal positioning for their Hydrodemolition project, regardless of the surface or environment,” Simonsson said. “The true value, however, lies in its reusability and scalability. If a future project requires different specifications, the system can be reconfigured or expanded with additional components. This flexibility reduces the need for entirely new setups, saving both time and resources, while keeping contractors prepared for any challenge that comes their way.”
Aquajet’s new Support System is designed to deliver even more flexibility and stability when working with the Aqua Spine 3.0 or the Ergo, offering a customizable solution that adapts to the specific demands of each job. Whether working on floors, walls or ceilings, the system ensures that contractors can position their equipment with remarkable accuracy, adjusting the height and angle of the components to provide optimal stability in any environment.
The system consists of support legs, brackets and joints that are easily adjustable in both height and angle and can be assembled to allow the Aqua Spine to rotate 360 degrees — either manually or hydraulically. Featuring only nine parts, the Support System uses interchangeable CC80 hole pattern and M16 screws, enabling quick reconfiguration from one project to the next. What truly sets this support system apart is its modularity. Contractors can select from light and heavy versions to meet the specific job needs. The light series is a lighter weight, flexible system ideal for the Ergo, while the heavy series is more stable and robust to handle a more powerful machine, like the Aqua Cutter 750V’s power head.
These systems can be adapted to a wide range of industries to remove any number of materials. It adapts to various surfaces — floors, walls or ceilings — allowing contractors to precisely adjust leg height and angle for optimal stability. Fully customizable for specific project requirements, the system’s reusability and scalability allow for future reconfiguration, saving time and resources by eliminating the need for entirely new setups.
