| 1 | Confirm pallet size and load weight | Specify the pallet footprint, total load weight, load overhang, and load-center position before selecting the conveyor frame and roller configuration. | Common pallet footprints: 40 × 48 in and 42 × 48 in Typical conveyor load rating: 500–4,000 lb | Allow clearance for the largest pallet and any unstable or irregular loads. Check that the conveyor can safely support the load during starts, stops, transfers, and accumulation. |
| 2 | Match conveyor width to the pallet | Select roller bed width so the pallet is fully supported while maintaining side clearance for guides, sensors, and maintenance access. | Minimum practical support: approximately 3 rollers beneath the pallet Typical side clearance: 3–6 in per side | Measure aisle openings, rack locations, dock doors, and equipment interfaces. Avoid selecting a width that creates pinch points or reduces required pedestrian and forklift clearance. |
| 3 | Choose the correct conveyor type | Use powered roller conveyor for controlled movement, accumulation, and transfers; use gravity roller conveyor where a simple downhill flow is acceptable and precise control is not required. | Gravity conveyor slope: about 1–3% Powered conveying: suitable for level or inclined sections and controlled routing | Map every origin, destination, merge, divert, and accumulation zone. Powered equipment is generally better for variable flow, long distances, frequent starts and stops, or automated interfaces. |
| 4 | Set speed and throughput targets | Size the conveyor around required pallets per hour, transfer spacing, dwell time, and the maximum safe speed for the load. | Typical pallet conveyor speed: 20–60 ft/min Higher speeds may require enhanced guarding, braking, and load stabilization | Compare conveyor capacity with receiving, picking, packaging, and shipping rates. Include buffer capacity so short-term surges do not stop upstream or downstream operations. |
| 5 | Plan accumulation and controls | Decide whether pallets will queue, release individually, or move in zones. Use sensors and zoned control when loads require controlled spacing. | Recommended control approach: zero-pressure accumulation for sensitive or mixed loads Common zone length: one pallet load plus operating clearance | Place accumulation before workstations, palletizers, wrappers, and shipping lanes. Confirm that sensors remain accessible and that queued pallets will not block emergency routes or fire equipment. |
| 6 | Account for transfers, curves, and elevation changes | Identify 90-degree transfers, merges, turntables, lift tables, and inclines during the initial layout rather than adding them after the conveyor route is fixed. | Typical transfer clearance: allow full pallet length and width at the handoff Curve planning: verify load stability and inside-corner clearance | Maintain a continuous load path around columns, walls, racks, and doors. Check turning envelopes for forklifts and service personnel, especially at intersections and conveyor corners. |
| 7 | Design for safety, maintenance, and future growth | Include guarding, emergency stops, lockout access, inspection points, spare capacity, and a clear maintenance path in the final design. | Design allowance for future demand: approximately 15–25% capacity reserve Emergency-stop coverage: accessible along the complete conveyor route | Keep controls, motors, sensors, and transfer mechanisms reachable without obstructing production. Reserve space for additional conveyor sections, scanners, sortation, or workstation changes. |
