Elevators using cleated or sidewall conveyor belts are an accepted solution for transferring product from one height to another. They can be used for elevation or as declines to take a product down as in an IQ freezer outfeed. Elevators can have one inclined section or additional horizontal sections that require the belt to ‘transition’ from one orientation to another. Elevators can be simple two-axle conveyors or they can have one horizontal section (L-shaped) or two horizontal sections (Z, swan-neck, or goose-neck).
The transition areas are usually constructed in a reverse form on the belt return path and in the zone where the belt flexes around an arc on the work side, it back-flexes in the same zone underneath the conveyor. Correct design of these areas is critical to prevent belt failure. In addition, larger pulleys will be required to allow the belt to flex due to the addition of fabricated elements such as cleats, sidewalls, or top guides.
Volta’s service team helps designers and users understand and utilize these options as well as avoid mistakes in underestimating their impact on elevator design. Volta offers numerous options of cleat types that can handle and contain product even at severe angles. Perpendicular scoop-cleated belts in conjunction with Volta Positive Drive belts, replace modular and bucket elevator belts. The benefits of this combination minimize cleaning and maintenance, reduce motor output, lower noise levels, and reduce the overall cost of ownership.
