Crawler Crane Undercarriage Parts include: Track Shoe, Track Roller, Top Roller, Idler and sprocket.
Different parts in the crawler crane have different roles:
The Crawler Chain consists of track shoes and pins, it can increase grounding area and sustain the machine.
The track roller look the same as the top roller. Track Roller can match shoe’s lug, let the track shoe run smoothly. Top Roller sustain the shoes and keep it from drooping. So, as usual, the top roller is smaller than track roller.
The hydraulic driving and reduction gear are located at end of each crawler side frame, they drive the sprocket, therefore drive the crawler crane. The idler usually is located at front of frame, it will lead the shoe into right path, keep it from deviating.
