Abstract
A method and apparatus for a conveyor tensioning system comprising a main frame with at least one main frame roller pivotally mounted thereto for engagement with a conveyor belt. A moveable frame is engaged with the main frame at an engagement interface such that the position of the moveable frame with respect to the main frame may be adjusted in at least one dimension. The moveable frame also includes at least one moveable frame roller pivotally mounted thereto for engagement with a conveyor belt. The position of the moveable frame with respect to the main frame may be actuated by hydraulic cylinders or other mechanical systems. As the distance between the main frame and moveable frame increases, the tension on the belt also increases.
