Improved components Modern Hydrodemolition machine’s components have
more functionality for improved performance. For example, today’s Hydrodemolition robots have a sensor in their hoist system to set the height of the hood, eliminating the need for operators to manually check. While some may think additional elements increase the likelihood of breakdowns, that isn’t the case. Components in new machines are designed to last and require less attention. Rollers, for example, had to be tightened daily on old machines. Today’s rollers use more components, are preset and much more durable, allowing operators to approach them with a set-it-and-forget-it mentality. It took time for the sensors equipped on new

Furthermore, it creates a rough but even result and virtually eliminates pipe holes, leaving behind the ideal bonding surface. Creating the perfect profile for superior bonding strength results in repairs that can last up to three times longer. This will please project engineers and prevent the job from being held up by subpar results.

Users can also adjust the machine to fluctuate speeds in different zones of the work area for deeper or more shallow removal where needed. This is another efficiency-enhancing feature, allowing operators to complete the removal in a single pass. For example, if the job requires removal 4 inches deep for the first half of the pass and 2 inches for the other section, the operator can set zones to accomplish this in one go. Operators can also set new machines to cut in a variety of shapes. So, the triangle shape left over from something like a bridge joint no longer needs to be removed manually by jackhammers or hand lances.
When an operation implements a machine that uses the infinity pattern, they’re making the most efficient use of all the force at their disposal. Contractors using equipment with an infinity pattern will typically increase efficiency by 15 to 20%, depending on the scope of the work. With the proper settings and depending what settings are changed, that number could increase to 50%. This can save significant time and money for things such as fuel if contractors can complete the project that much faster. This represents state-of-the-art engineering
Right: Creating the perfect profile for superior bonding strength results in repairs that can last up to three times longer. This will please project engineers and prevent the project from being held up by subpar results
Far right: The constant speed and continuous movement of an infinity pattern removes more concrete in a single pass and leaves behind a more consistent result

with precision and control previously thought unattainable. Contractors and their crews can take pride in knowing they are using the most advanced, efficient and powerful tools available to set a new standard in their industry.
Hydrodemolition robots to catch on and be more accepted, but they’ve made great strides in terms of reliability. They’re well-sealed mechanisms and handle stress from operation well, meaning far less upkeep. Previously, if a sensor was tied to a cable and the cable needed to be replaced, the sensor did, as well. With optimized sensors, one can simply replace the cable and get back to work. New and improved components in today’s equipment give contractors a competitive advantage by helping minimize downtime and keep projects on track.
Speaking of tracks — those can impact a project’s quality and efficiency. Take a bridge job, for instance. Sometimes, operators will have to drive the machine up to a couple-hundred feet to the work area. New track systems allow the Hydrodemolition robot to travel 50 meters per minute opposed to 30 with an older machine. The modern track systems also provide a smoother ride, reducing wear on the machine and increased stability during operation. Adopting new technology seems like a significant
step, but it’s important to consider the long-term benefits of reduced maintenance costs, more reliable equipment, faster project turnaround times and an easier route to profitability.
Modern machines produce optimum results
Investing in new technology can seem unnecessary if you have equipment that still gets the job done. But Hydrodemolition contractors are no longer competing with jackhammers and hand lances. They are competing with new Hydrodemolition technology that is rapidly building on yesterday’s advancements, allowing those who invest to achieve better results faster and easier. Upgrading to today’s equipment isn’t just about staying with the pack, it’s about paving the way and becoming a leader in the field. Contractors adopting the latest technology invest in their team’s success and company’s future by maximizing their potential.
