1. A pipeline padding machine elevator self-cleaning system comprising:

  • a steel mounting plate with a bolt pattern designed to be installed on a pipeline padding machine elevator comprising a plurality of flights;

    a flexible wire cable directed at an angle to engage built up soil or clay in a space between the elevator flights and an elevator side wall; and

    an adjustable spacer fixture for securing the flexible wire cable to the mounting plate, wherein the spacer fixture provides for adjusting the cable and a clearance between the cable and elevator side wall;

    wherein the system is installed by bolting onto at least one of the elevator flights;

    wherein the system is driven upwards and around the elevator by an elevator drive mechanism; and

    wherein the upwards travel engages the flexible wire cable into the built up soil or clay, removing debris that would occur between the flights and the side wall of the elevator and allows the padding machine to be operated for longer periods of time before stoppage for cleaning and power washing.
