Maxwell working robots

Electric cutting technology



The Maxwell electric cutter series offers a complete range of robots to support rehabilitation operations (CIPP) and maintenance of sewer pipes. These robots have been specially designed to carry out grinding and milling tasks targeting deposits, root intrusion, joints and reopening laterals after relining. A wide range of heads and options increase the versatility of the systems. These electrically driven robots offer powerful cutting torque, lightweight construction, reduced noise and no exhaust gases.
