A wedge conveyor is always used if the conveyed product (1) cannot be transported vertically on a standard conveyor due to its design, (2) cannot manage steep inclinations <gt/> 30° due to the position of its center of gravity, (3) has sensitive surfaces that would be damaged by lateral or upper guides, (4) must not slide on 90° gradient or decline section (as it would occur with a cleated chain system) or (5) should be conveyed without synchronization.
