The new Automated Remote Manipulator (ARM) from NLB Corp. is a semi-automated water jet system that increases operator protection while reducing downtime. It lets an operator manipulate a variety of accessories from the safety and comfort of a climate-controlled cab, using convenient joystick controls to position them and to start and stop the flow of high-pressure water (up to 40,000 psi, or 2,760 bar, at 600 hp). With specialized tooling mounted on the arm of a mini excavator, the ARM handles applications as diverse as shellside tube bundle cleaning and hydrodemolition. The ARM has a vertical reach of about 12 feet and a horizontal reach of about 17 feet, with a wide water jet pattern to maximize coverage. This allows the operator to stay out of the action, not only reducing risk but eliminating the fatigue of manual water jetting and the possibility of inconsistent results from operators with different skill levels.
