PIPELINE PADDING MACHINE WITH A DEBRIS-RESISTANT ESCALATOR ASSEMBLY
First Claim
1. A pipeline padding machine, comprising:
- an escalator assembly including multiple flight sections attached to a track, and wherein a gap between leading and trailing edges of respective adjacent flight sections is substantially the same when the track is substantially straight, and when the track is at its maximum curvature.

Abstract
A pipeline padding machine includes a debris-resistant escalator flight. A pipeline padding machine includes an escalator assembly with multiple flight sections attached to a track. A gap between leading and trailing edges of respective adjacent flight sections may be substantially the same when the track is substantially straight, and when the track is at its maximum curvature. Leading and trailing edge portions of each flight section may be angled relative to a longitudinal axis of a corresponding track section by a same angle as that between adjacent track sections when the track is at its maximum curvature. The edge portions of respective adjacent flight sections may be substantially parallel to each other when the track is at its maximum curvature.
