The new automated remote manipulator (ARM) from NLB Corp. is a semi-automated water jet system that increases operator protection while reducing downtime, the company says. The ARM lets an operator manipulate a variety of accessories from the cab using 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 such as shell-side tube bundle cleaning and hydrodemolition. Its quick-connect system makes it easy to change accessories, NLB adds.
According to a press release, the ARM has a vertical reach of about 12 ft. and a horizontal reach of about 17 ft., with a wide water jet pattern to maximize coverage. This allows operators to stay out of the action, NLB says.
