VT150 Vertical Crawler

Adjust To Size. Power To Spare.

The VT150 Vertical Crawler™ is a unique inspection robotic solution for asset integrity condition assessments of those seemingly inaccessible industrial locations. Based on the proven VT100 Vertical Crawler™, this robust system employs three Minitracs™ and an expandable tripod chassis, allowing it to perform difficult inspections over a range of pipe sizes in virtually any orientation.


  • Operates in pipes ranging from 406–914 mm (16–36 in) with remote pipe adjusting chassis*
  • Works on any incline from horizontal to vertical
  • Independent track control for easy navigation around multiple bends and vertical pipe segments
  • Travels distances as far as 900 m (3000 ft) in a single run**
  • Option for high definition camera for more detailed remote visual inspection


Key Industries

  • Oil and Gas (onshore and offshore)
  • Petrochemical
  • Nuclear
  • Mining

Key Applications

The VT150 Vertical Crawler (VT150VC) employs field proven Minitracs and an Spectrum 90™ pan, tilt and zoom inspection camera for a variety of remote visual inspection applications across a range of applications. This remotely operated robotic crawler is ideal for inspection of flexible risers, vertical and inclined pipework and caissons, vertical air and seawater intakes, oil and gas refineries, water and sewer pipelines and other vertical non-ferrous infrastructure requiring integrity assessment.

Special versions have included a rotation drive for precision radial positioning, and a bidirectional shuttle for multi-tool deployment. This flexible system is ready for your unique inspection requirements.
