ABSTRACT:
A device for raising and lowering a paper roll used in a printing press. This device is comprised of an inverted U-shaped frame made up of a horizontal member supported by two vertical members. Two hydraulic cylinders are supported by the horizontal member so that each extends substantially parallel to a vertical member of the frame. A hydraulic power unit is attached to the top of the horizontal member to actuate the hydraulic cylinders. A hydraulic directional control valve controls the direction of flow of hydraulic fluid in order to effectuate the extension and retraction of the hydraulic cylinders and thereby raise and lower the paper roll.
