renchless Australasia sat down and spoke with Sewer Robotics Sales and Export Manager Bart van der Zalm at No-Dig Down Under 2023 about the system and its different modules. Manufactured by Sewer Robotics in the Netherlands, the one system is classified as highly effective and cost-effective. It can remove root intrusions, cut protruding traps, and reinstate lateral connections, install spot repair systems and remove heavy grease. “There’s a one-stop-shop element, which is really beneficial,” van der Zalm said. “The precision jet cutting with the ultrahigh pressure water jet can be used to remove

nearly any obstacle like settled deposits, cement, concrete and grout.” Utilities management service, Pipe Management Australia, recently purchased its first unit of the Sewer Robotics crawler to service difficult jobs. “We bought the unit to tackle some of the harder concrete deposits so, it gives us a competitive edge,” Pipe Management Australia Co-founder and Chief Innovations Officer Luke Moore said. “For us, we would use it for major root removals, hardened concrete deposits and with the additional attachment of the grinding head,
it can cut back intrusions as well.” Due to the multifunctional nature of the crawler and its various job-specific modules, it can be used across multiple applications. The R125 crawler has a maximised clearance inside 150mm pipelines and features a twist and lock mechanism to exchange the modules. It can also easily transform from powerful cutter to a water jet cutter by swapping out the modules in less than one minute. Lateral reinstatement cutting One module example is the HA125 – a lateral reinstatement cutter that can be used inside 500mm pipelines and 150mm relined pipelines. The 90-degree cutter and 205mm ram lift are key for durability and precision without the need for hydraulics inside the crawler. It is also easy to service and features a powerful cutter motor, great camera visibility and user-friendly controls. Water jet cutting The WJ125 water jet cutter is just one example of Sewer Robotics’ 17 years’ experience of UHP water jet cutting. This module applies a continuous highpressure blast from the crawler for a controlled removal of deposits settled from within 150mm to 1000mm pipes and their connections. With up to 3000BAR, the precision water jet cutting can remove fog, debris, roots, cement, scale, tuberculation, grout, calcium and concrete.
