Our columns and booms – ranging from 1.5 x 1 metres up to 8 x 8 metres for column stroke and boom range – are used for the positioning and guidance of welding heads, welding torches and other tools. Columns & booms can thus be combined with positioners and/or roller beds in a variety of applications such as the welding of circumferential or longitudinal seams or the build-up welding of alloys on workpieces.

The standard versions of our columns & booms have the following features:

  • Lean or heavy-duty design, depending on the maximum boom load, the smoothness of motion (low vibration) and boom length
  • Guides on the column & boom consisting of gear racks and linear guides
  • Standard control

Possible optional extras:

  • Undercarriage
  • Operator’s seat mounted at the front end of the boom (heavy-duty version only)

In addition to the standard models mentioned above, we can also design column & boom combinations with other lengths.

Detailed information can be supplied on request.
