| 1 | Receiving and Shipping Docks | Moves cartons, totes, and pallets between dock doors, staging areas, and storage zones. | Cartons, totes, pallets | Gravity roller conveyor or powered roller conveyor | Approximately 75–150 mm for cartons; heavier-duty spacing for pallets | Gravity for short, level-assisted movement; powered sections for controlled flow | Load capacity, corrosion resistance, dock integration, adjustable supports, and impact protection |
| 2 | Warehouse Pallet Handling | Transports unit loads between pallet storage, picking areas, wrapping stations, and dispatch points. | Standard pallets and skids | Heavy-duty chain-driven roller conveyor or pallet roller conveyor | Usually selected so several rollers support the pallet at all times | Motorized drive required for accumulation, incline movement, or high throughput | Rated load per pallet, frame rigidity, drive torque, safety guarding, and maintenance access |
| 3 | E-Commerce Order Fulfillment | Transfers picked items, cartons, and totes between picking, packing, sortation, and shipping zones. | Polymer totes, cartons, mailers | Motor-driven roller conveyor, zero-pressure accumulation, and flexible sections | Commonly about 50–100 mm for small cartons and totes | Zone-controlled motors or motorized rollers for product spacing and accumulation | Low-noise operation, variable speed control, barcode-system compatibility, and modular expansion |
| 4 | Parcel Sortation | Feeds packages to scanning, diverting, merging, and destination-routing equipment. | Parcels, cartons, polybags | Powered roller conveyor with merges, transfers, and pop-up divert units | Selected according to the smallest package footprint and stability requirements | Powered operation with sensors, controls, and synchronized divert mechanisms | Throughput, package-size range, tracking accuracy, sensor integration, and emergency-stop coverage |
| 5 | Packaging Lines | Moves filled cases, trays, and containers between filling, sealing, labeling, weighing, and palletizing equipment. | Cases, trays, cartons, containers | Stainless-steel or coated powered roller conveyor; accumulation sections where required | Typically based on container length, bottom condition, and required product stability | Powered drive is generally used for synchronized line movement | Washdown rating, hygienic design, belt or roller surface selection, line speed, and cleanability |
| 6 | Manufacturing and Assembly | Positions work-in-process materials, components, and finished products at assembly or inspection stations. | Bins, fixtures, totes, workpieces | Gravity roller conveyor, powered roller conveyor, or roller-top workstation conveyor | Chosen to prevent small parts from falling between rollers | Gravity for manual feeding; powered movement for automated or repetitive workflows | Ergonomics, workstation height, precision positioning, ESD requirements, and load stability |
| 7 | Food and Beverage Processing | Conveys packaged food, cases, trays, and containers through processing, inspection, and distribution areas. | Food cartons, plastic crates, bottles, cases | Stainless-steel roller conveyor or sanitary powered roller conveyor | Determined by package dimensions and hygiene-related drainage requirements | Powered drive for continuous lines, accumulation, and controlled transfers | Food-compatible materials, open-frame construction, drainage, washdown capability, and hygienic lubrication |
| 8 | Cold Storage and Refrigerated Logistics | Handles frozen or chilled cartons, totes, and pallets in temperature-controlled warehouses. | Frozen-food cases, insulated totes, pallets | Corrosion-resistant powered roller conveyor or heavy-duty pallet roller conveyor | Selected for reliable movement under low-temperature and condensation conditions | Powered drive is preferred for cold-room inclines, accumulation, and long conveyor runs | Low-temperature components, sealed bearings, corrosion resistance, insulation interfaces, and serviceability |
| 9 | Airport Baggage Handling | Transfers baggage between check-in, screening, sorting, make-up, and reclaim areas. | Suitcases, bags, bins | Powered roller conveyor with merges, transfers, curves, and control-system integration | Selected to support baggage bases while limiting snagging and instability | Powered and sensor-controlled operation is required for automated baggage routing | High availability, noise control, tracking integration, safety systems, and continuous-duty performance |
| 10 | Automotive and Heavy-Component Logistics | Moves engines, transmissions, metal components, pallets, and returnable containers through production facilities. | Steel stillages, pallets, bins, heavy components | Heavy-duty chain-driven roller conveyor or line-shaft roller conveyor | Usually wider roller diameter and closer support spacing for concentrated loads | Powered drive required for heavy loads, accumulation, transfers, and production-line synchronization | Load rating, shock resistance, frame strength, drive redundancy, guarding, and integration with automation |
