120 mm Ten Wheel Drive Pipe Crawler

Key features

  • 120 mm to 150 mm diameter adjustable

  • Up to 140 Newtons of force dependent upon wheel grip – 70 Newtons Typical

  • 270 mm long

  • Compliance to ensure force at differing diameters and around bends

  • 10 x DC motors and gearboxes with proportional control


High speed wheel powered crawlers are needed to push or pull other instrumentation into pipes such as cameras, sensors or laser measurement devices and navigating bends.


This crawler is capable of going into pipes with a diameter ranging from 120 mm upwards to 150 mm. Being compliant and adjustable allows the crawler to navigate around bends up to 1.5-D.


Each wheel is powered so in the event that one wheel does not have full traction another wheel will still be operating. The wheels provide a point contact with the pipe surface and hence less grip compared to tracked systems have a considerable area of contact with the pipe.
