NLB Corp. has introduced wireless controls for its automated water jet Crawler, designed to achieve high-productivity surface preparation on towers and other large structures, the company says.
The NLB SRT-10-W Crawler removes coatings and scale using ultra-high pressure (UHP) water up to 40,000 psi (2,800 bar) that passes through from patented rotating nozzles.
The Crawler, controlled by an operator on the ground, moves up, down and across to strip storage tanks, ship hulls and other tall surfaces down to bare metal. The new wireless controls let a single operator direct the entire job from as far away as 1,500 feet and reduce the potential for tangled wires, NLB points out.
NLB says that users of its Crawlers report removal rates of up to 2,000 square feet per day, with reduced risk to the environment as well as to operating personnel.
The NLB SRT-10-W Crawler uses no abrasive and has vacuum recovery to contain the water and debris. No other containment is needed to protect the surrounding area, reducing clean-up and operating costs.

NLB manufactures a full line of water jetting pump units and accessories for contractor and industrial uses, including surface preparation, product removal, tank and tube bundle cleaning, pavement stripe and rubber removal, concrete hydrodemolition and concrete and pipe cutting.
