| 1Confirm the real load profile | Rated load, pallet size, load distribution, and operating duty | Check both maximum pallet weight and the actual contact points between the pallet and rollers. Confirm whether the load is evenly distributed, overhanging, wrapped, or unstable. | Define the nominal pallet footprint, such as 1,200 × 800 mm or 1,200 × 1,000 mm, and specify the maximum gross load in kilograms. The conveyor should be rated for the heaviest planned load, not the average load. | Correct sizing reduces premature bearing, roller, frame, and drive failures. Oversizing can increase steel, motor, and installation costs. | Provide a written load matrix covering minimum, average, maximum, and abnormal loads. |
| 2Audit supplier quality controls | Manufacturing capability, inspection records, and traceability | Request process controls for frame welding, roller alignment, surface treatment, electrical assembly, final testing, and spare-parts identification. Verify whether inspection results are recorded by serial number or production batch. | A credible quality program should include documented incoming inspection, in-process checks, final functional testing, nonconformance handling, and calibration records for measuring equipment. ISO 9001 certification may support the audit but does not replace product inspection. | Strong process control lowers rework, site installation delays, commissioning costs, and warranty disputes. | Use a pre-shipment inspection checklist with measurable acceptance criteria and photographs. |
| 3Verify global safety compliance | Machine safety, guarding, emergency stops, and electrical conformity | Confirm the intended destination and applicable legal requirements before design approval. Review the risk assessment, safety circuit design, guarding layout, emergency-stop coverage, electrical drawings, and declaration documents. | Common reference points include ISO 12100 for machinery risk assessment, ISO 13849-1 for safety-related control systems, and IEC 60204-1 for electrical equipment of machinery. Market-specific requirements may also apply, including EU or UK conformity obligations and local workplace-safety rules. | Compliance failures can create shipment holds, redesign costs, customs delays, site shutdowns, and legal exposure. | Specify the target country, voltage, frequency, language, documentation, and required conformity route in the purchase contract. |
| 4Match performance to the process | Speed, accumulation, throughput, starts per hour, and control integration | Ask for tested performance at the actual pallet weight and pallet condition. Verify accumulation logic, zero-pressure requirements, transfer timing, sensor response, restart behavior, and interface compatibility with PLC, WMS, or warehouse control systems. | Many pallet conveyor applications operate within approximately 0.1–0.5 m/s, but the correct value depends on pallet stability, transfer distance, spacing, and throughput. Define throughput in pallets per hour rather than relying only on belt or roller speed. | Proper process matching avoids unnecessary motor capacity, excessive energy use, product damage, and bottlenecks at transfers. | Require a throughput calculation and an acceptance test using representative pallets. |
| 5Check environmental suitability | Temperature, humidity, dust, washdown, corrosion, and floor conditions | Confirm enclosure ratings, coating system, stainless or treated components where needed, lubrication requirements, drainage, cable protection, and allowable floor levelness. Verify the operating environment rather than selecting protection based only on price. | Specify the ambient temperature range, relative humidity, dust exposure, cleaning method, and chemical contact. IP ratings describe protection against solid objects and water for electrical enclosures; they do not automatically prove corrosion resistance or suitability for high-pressure washdown. | Correct environmental protection extends service life and reduces corrosion, electrical faults, cleaning downtime, and replacement-part consumption. | Include environmental conditions and cleaning procedures in the technical specification and site survey. |
| 6Calculate total cost of ownership | Purchase price, freight, installation, energy, maintenance, downtime, and replacement parts | Request a cost breakdown for equipment, controls, packaging, export documentation, freight, duties, commissioning, training, recommended spares, and warranty exclusions. Compare energy and maintenance assumptions using the same operating hours. | Use a five-year model: TCO = purchase price + logistics + installation + energy + planned maintenance + corrective maintenance + downtime cost − residual value. Separately identify one-time costs and recurring annual costs. | The lowest quotation may become more expensive when freight, local labor, spare parts, downtime, and compliance work are included. | Compare suppliers with a standardized landed-cost and five-year operating-cost worksheet. |
| 7Secure after-sales support and spares | Warranty, response time, documentation, training, and spare-parts availability | Verify warranty duration and scope, remote-support hours, escalation contacts, troubleshooting procedures, spare-parts lead times, software access, and responsibility for field service. Ensure manuals and drawings are supplied in the required language. | The spare-parts list should identify critical items such as motors, gear units, rollers, sensors, belts or chains, bearings, fuses, safety devices, and control components. Define response and resolution targets in the service agreement. | Accessible support reduces mean time to repair, production losses, emergency freight, and dependence on a single overseas shipment. | Purchase critical spares before commissioning and obtain complete as-built drawings, parameter backups, and maintenance schedules. |
