English term or phrase:Return idler
The bucket elevator must be tightened with the tensioning device situated on the tail section. First compress each spring by 20 mm. If the spring tension becomes less than 5 mm, compress the spring again. The chain must be in a flat position on the bottom or on the rail, it must never buckle in any position inside the elevator.
Should the tensioning device reach its end position, a link must be removed and the chain tightened again.
The return IDLER must be parallel to the side plates in order to avoid additional wear and noise.
