The Viper Crawler System

  • Strong permanent magnetic wheels hold the system to the magnetic surface even through several layers of paint
  • Long lasting, high torque planetary gear mechanism for travel over welds and patch plates
  • Inspect tanks, piping, pressure vessels, duct work, etc.
  • Optional encoder for distance processing
  • Zero turn-radius for fast and accurate maneuverability
  • Offset wheel design allows maximum surface contact at all times
  • Operates at variable speeds through a handheld controller
