| Load capacity and product fit | Confirm the conveyor is designed for the maximum unit load, load distribution, product dimensions, and any concentrated or overhanging loads. | Written capacity for the proposed configuration; product and load assumptions documented; safety factor and operating limits stated for the application. | 15% |
| Roller selection and spacing | Check roller diameter, material, bearing type, and pitch against package size, weight, base condition, and desired movement. | Layout or specification identifies roller details. Roller pitch is suitable for the smallest product base, with adequate support during transfer. | 12% |
| Frame and finish quality | Review frame material, structural design, corrosion protection, edges, welds, and finish for the operating environment. | Material and finish specifications are provided; workmanship is consistent; coating or stainless-steel selection matches exposure and cleaning needs. | 12% |
| Engineering and configuration capability | Assess the ability to configure straight sections, curves, stops, supports, transitions, and interfaces with adjacent equipment. | Application-specific drawings show dimensions, elevations, connections, and options; design changes are reviewed and documented. | 12% |
| Performance and operating safety | For gravity applications, evaluate slope, starting and running behavior, product control, and potential pinch or impact points. | Proposed slope and operating assumptions are documented; the supplier explains how speed, accumulation, and safe access will be addressed. | 10% |
| Dimensional accuracy and assembly | Check consistency of section lengths, widths, elevations, hole patterns, and connection points. | Inspection is performed against approved drawings; critical tolerances are specified rather than assumed; sections align during installation. | 10% |
| Quality control and traceability | Review inspection procedures for incoming materials, fabrication, finishing, and final assembly. | Documented quality checks and inspection records are available. Applicable quality-system certifications can be verified when claimed. | 10% |
| Testing and delivery inspection | Determine what checks are completed before shipment and how discrepancies are managed. | Inspection checklist covers the agreed configuration, dimensions, finish, and included components; nonconformances have a defined resolution process. | 7% |
| Installation documents and support | Assess the clarity of assembly, anchoring, maintenance, and operating instructions, plus access to technical assistance. | Manuals and drawings are supplied for the delivered system; maintenance guidance identifies inspection points and replaceable parts. | 6% |
| Spare parts and lifecycle support | Check availability of common replacement items such as rollers, bearings, and connection hardware. | Parts are identifiable from documentation; the supplier states availability, ordering information, and support arrangements. | 6% |
