| Rated Load Capacity | 1,000–2,000 kg for warehouse pallet handling | Common electric stacker classes: 1,000 kg, 1,200 kg, 1,500 kg, and 2,000 kg | Rated-capacity plate, load chart, test report, and operating manual | Confirm the capacity at the required lift height, not only the maximum rated capacity. |
| Lift Height | 1,600–3,500 mm for standard warehouse racking | Manual, semi-electric, and fully electric models commonly cover approximately 1,600–5,500 mm | Mast specification, residual-capacity chart, and lifting-cycle test | A higher mast can reduce residual capacity and increase the required overhead clearance. |
| Drive and Lift Configuration | Electric travel and electric lifting for frequent pallet movement | Walkie stackers, platform stackers, and ride-on stackers are the main configurations | Electrical schematic, motor ratings, controller specification, and demonstration video | Choose a walkie model for short travel distances and a platform or ride-on model for higher daily operating hours. |
| Battery System | 24 V battery system is common for compact warehouse stackers | Lead-acid batteries often range from about 60–240 Ah; lithium-ion options are generally lighter and support opportunity charging | Battery datasheet, charger compatibility, safety data sheet, and replacement cost | Compare total operating cost, charging time, battery cycle life, ambient temperature limits, and local recycling requirements. |
| Performance | Controlled travel speed and stable lifting under the specified load | Typical no-load travel speeds are approximately 4–6 km/h; lifting speeds vary by load and model | Factory acceptance test, speed settings, braking test, and loaded lifting test | Evaluate productivity together with braking distance, maneuverability, noise, and operator visibility. |
| Safety and Compliance | Compliance with the destination market’s machinery and workplace-safety rules | ISO 3691-1 is a key international reference for industrial trucks; additional local requirements may apply | Declaration of conformity, risk assessment, safety test records, and applicable electrical reports | Do not treat a general certificate as proof of compliance for every destination country. |
| Indicative Export Price | Compare equivalent capacity, mast, battery, charger, and control features | Approximately USD 1,500–3,500 for many basic electric walkie stackers; higher-capacity or lithium-ion configurations can exceed USD 5,000 | Itemized quotation, Incoterm, packaging details, spare-parts pricing, and payment terms | Use the same technical specification and Incoterm when comparing quotations. |
| Total Landed Cost | Budget for transport, insurance, import duty, VAT, inland delivery, and commissioning | Landed cost can be materially higher than the factory quotation, depending on destination, shipment size, and customs classification | Commercial invoice, packing list, HS code confirmation, freight quotation, and customs documents | Request a destination-specific landed-cost calculation before selecting the lowest factory price. |
| Minimum Order and Lead Time | One sample unit for testing, followed by repeat orders if performance is acceptable | Stock units may ship within 1–2 weeks; customized or production orders commonly require about 4–8 weeks | Written production schedule, sample policy, inspection milestones, and delay provisions | Confirm whether the quoted lead time includes battery preparation, testing, export packing, and documentation. |
| Warranty Coverage | Clear coverage for the complete machine and separate terms for battery and wearing parts | Many export quotations offer approximately 12 months for the machine, subject to stated exclusions | Warranty certificate, exclusion list, claim procedure, response-time commitment, and labor policy | Clarify whether freight, labor, replacement parts, and technician travel are included in warranty support. |
| After-Sales Support | Remote troubleshooting plus access to replacement parts and service manuals | A practical benchmark is technical reply within 1 business day and parts dispatch within 3–10 business days when stock is available | Service-level agreement, parts stock list, wiring diagrams, fault-code guide, and training plan | Assess support capability in the buyer’s time zone and language, not only the quoted warranty period. |
| Spare Parts Availability | Fast access to wheels, forks, batteries, chargers, controllers, switches, and hydraulic components | Critical wear parts should normally be planned for 12–24 months of expected use | Recommended spare-parts list, unit prices, stock location, shelf life, and part-number system | Obtain prices for a complete maintenance kit before placing the equipment order. |
| Supplier Verification | Traceable manufacturing capability and consistent export documentation | Verify legal registration, production capability, quality controls, export history, and independent inspection results | Business license, factory audit, quality-system records, reference shipments, and pre-shipment inspection report | Prefer documented evidence and a physical or third-party inspection over online claims alone. |
| Recommended Selection Method | Shortlist at least three technically equivalent quotations | Suggested weighting: 30% technical fit, 25% total landed cost, 20% safety and quality, 15% after-sales support, and 10% delivery capability | Completed comparison matrix, sample-test record, inspection report, and signed commercial terms | The best choice is normally the supplier with the strongest verified total value, not the lowest initial quotation. |
