Abstract
Abstract A vertical lift construction for moving articles from one level to another comprising a frame with endless conveyors located on opposite sides of the frame. Each of the conveyors carries a plurality of article supporting elements with the elements moving in the same direction on the inwardly facing side of the conveyors. Articles are adapted to be located on the respective article supporting elements so that the ends only of the articles are supported with the main body of the articles being suspended in unsupported fashion between the article supporting elements. The frames for supporting the conveyors are relatively movable by motorized means so that the span between article supporting elements can be readily changed for handling articles of different sizes.
