Abstract
The system and method comprising at least one idler wheel for use with a drag chain mechanism. The device for use with the idler wheel has a rotatable shaft for receiving the rotational force of the idler wheel, and transmits that force to a rotation indicator which is external to the enclosed space where the idler wheel is located. The rotation indicator thus provides a reliable method for indicating to an external sensor or operator whether an idler wheel is rotating within acceptable operational parameters.
