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.

1. A system for maintaining tension of a drag slat chain within a predetermined tension range, said system comprising a driving means for rotating said drag slat chain and an actuating member associated with a torque and timing assembly for translating movement of the actuating member to reposition said driving means, said actuating member mechanically associated with the driving means, the system further comprising a tension range member, a lever, and at least one hydraulic cylinder for moving said actuating member, said lever comprising a securing member and mechanically coupled to said driving means, said tension range member comprising adjustable securement means wherein activation of said at least one hydraulic cylinder causes a movement of the actuating member and the lever a distance relative to the slack in the drag slat chain. 2. The system of claim 1, said movement causing said securing member to move relative to the adjustable securement means and if aligned therewith become secured therein. 3. The system of claim 2 wherein said adjustable securement means comprises a plurality of slots in which said securing member may be secured.
