1. A light grid system for rope machinery, the rope machinery including a rope drum having a center line, and a rope wrapped around the rope drum, the rope configured to maneuver a machinery component, the light grid system comprising:

  • one or more light grid assemblies, comprising;

    sensor frames coupled substantially perpendicularly to one or more vertical post assemblies, wherein the sensor frames are configured to mount substantially parallel to the axis of rotation of the rope drum and extending along the length of the rope drum; and

    sensors coupled to and positioned along the length of the sensor frames, the sensor frames including at least a first sensor frame having sensors configured to emit one or more light beams, and at least a second sensor frame having sensors configured to receive the one or more light beams, such that the one or more light beams are configured to extend across the width of the rope drum and in a plane substantially perpendicular to the axis of rotation of the rope drum, and wherein the sensors are adjustable relative to the sensor frames to move the one or more light beams horizontally relative to the rope drum and in a direction parallel to the axis of rotation of the rope drum;

    wherein the one or more light beams are positionable a predetermined distance away from the rope; and

    wherein the one or more light grid assemblies are configured to transmit a signal to a control module associated with the rope machinery when at least one of the one or more light beams is obstructed.
