A conveyor lifter bar, also known as a skirt lifter or belt lifter, is a specialized component used in conveyor systems to assist in maintaining proper material flow and prevent spillage along the conveyor belt's sides. These bars are designed to lift the edges of the conveyor belt slightly, creating a seal to contain material and minimize dust emissions at transfer points.

They help improve material containment, reduce spillage, and enhance the overall efficiency and cleanliness of the conveyor system.
