Abstract
Adjustment and tensioning of a drag slat chain system is necessary in order to best handle loads while keeping the drag moving and minimizing chances of the chain jumping the sprocket. An automated means of such adjustment is accomplished by providing a known force to tension the chain to a known “slack” and then automatically setting a mechanical stop to maintain an “ideal” tension range.
