Pass-throughs are conveyor sections that can retract or pivot vertically or horizontally to gain access for personnel, carts, and fork trucks on a production line. They can reduce the overall footprint of a production line by removing detours for access. They are safe, ergonomic and eliminate the need for walk-overs and duck-unders. Pack Air’s offerings range from simple flip-up deadplates, to powered flip-up conveyor sections, to our innovative and effective powered retractable conveyor sections.
