Abstract
An assembly for replacing the top sigma sections in a tail drive of an armored face conveyor is described. The assembly joins the sigmas to the top deck in a single unit, providing more robust mounting support. The assembly may also include one or more mounting pins, as well as one or more access doors. The assembly requires no welding to the tail drive.
