    How To Spot Excessive Wear in Undercarriages

    By staying vigilant and regularly examining your equipment, you can spot potential issues early and take proactive measures to avoid costly repairs down the line. Here are three key indicators to watch for when assessing the condition of your steel undercarriages.

    Inspect Track Tension and Sag

    Regularly examine the track tension and sag to identify signs of excessive wear. Excessive sagging or overtightening can both be indicators of potential undercarriage issues.

    Check for Uneven Wear Patterns

    Pay close attention to any uneven wear patterns on the track shoes and links. Irregular or asymmetrical wear can suggest misalignment or other underlying problems.

    Monitor for Abnormal Noises and Vibrations

    Keep an ear out for any unusual noises or vibrations during operation. Excessive vibration or strange sounds may signal that components are not functioning correctly.
