For big vertical jobs, like 100-foot storage tanks and ships hulls, more and more contractors are moving up to the NLB SRT-10-W-1 Crawler. While personnel stay safely on the ground, it crawls up, down and sideways - directed from wireless controls - while rotating SPIN JET nozzles do all the work.
The Crawler uses a vacuum system to grip the surface and to recover waste-water and debris, minimising clean-up. A winch skid assembly with locking pulleys allows an operator to position the unit and also servers as a fall arrest system.
The SRT-10-W-1 Crawler can be used horizontally as well as vertically. it cleans over welds and plates as thick as 1/2" (12.7mm).
Water Jet Vs Grit
When you consider all the factors, NLB's HydroPrep system consistently outperforms grit blasting. In addition to achieving a quality surface, water jetting:
- significantly simplifies clean-up and disposal
- minimises operating and maintenance costs
- can be performed nearly anywhere
- drastically reduces airborne pollutants
- removes invisible contaminants (e.g. entrapped chlorides)
- is virtually dust-free, so won't damage nearby equipment
- operates at lower sound levels
- uses minimal water
- requires minimal training.
