Abstract
Traveling support apparatus for supporting welding device or other apparatus for peripheral travel about a pipe. The support apparatus utilizes endless belts disposed around paired wheels at opposite sides of the apparatus to propel the apparatus along a track. The endless belts are pivotally supported for equal pressure engagements with the path along which the support apparatus travels. The support apparatus engages opposite sides of a track in the form of a strip or band spacedly surrounding a pipe to support a frame which is held firmly against movements toward or away from the track so that the supported apparatus is reliably held in position with relation to the pipe.
