ABSTRACT:
The present invention, in certain embodiments, is an apparatus for the movement of objects on rollers. The apparatus comprises a frame element, a series of rollers, a rotating pipe element suspended over the series of rollers, at least one push-arm assembly connected to the rotating pipe element, and a drive apparatus to actuate the rotating pipe element. The series of rollers are mounted in the frame element such that each roller in the series of rollers rotates within the frame element so that the objects resting on the series of rollers may travel from a first end of the series of rollers to a second terminal end of the series of rollers. The rotating pipe element is suspended over the series of rollers, and the rotating pipe element pivots along a longitudinal axis and is driven at one end. The drive apparatus actuates the rotating pipe element, thereby moving the at least one push-arm assembly to a position in contact with at least one of the objects to move along the series of rollers.
