    Abstract: The method of conveying elements on a conveyor system of this invention includes conveying an element on a first continuously moving conveyor in a first direction at a first height, then lifting the element from the first conveyor upwardly to a second height and simultaneously moving the element in the first direction, reducing damage to the conveyor and the element. The element may be returned to the first conveyor by lowering the element and simultaneously accelerating the element to generally the velocity of the first conveyor or transferred to a second conveyor at the second height. The conveyor system of this invention includes spaced parallel plastic moving belts and the elements are conveyed on a pallet having a soft metal base. The lift tables include parallelogram lift and lowering linkages.
