Six standard after-sales service components for machinery and equipment (based on GB/T 16784-2025 General Rules for After-Sales Service of Industrial Products): ① Installation and Commissioning (on-site installation + commissioning until ready for normal production); ② Operation Training (training for operators and maintenance personnel); ③ Warranty and Repair (12 months from the date of installation; covers parts and labor); ④ Spare Parts Supply (48-hour shipment / local spare parts warehouse); ⑤ Remote Support (24/7 video support + PLC remote diagnostics; 4-hour initial response time); ⑥ Periodic Maintenance (preventive maintenance plan)—major machinery exporters typically provide overseas service centers and spare parts networks.
I. Installation, Commissioning, and Training
Installation and Commissioning: Manufacturer dispatches engineers for on-site installation, synchronization, and trial production (continuing until final acceptance and sign-off);
Training: Training for operators and maintenance personnel (3 days on-site or 1 week at the factory; includes assessment and certification, following standards like Komatsu’s); Manuals: Operation manuals, installation videos, and training checklists—installation and commissioning constitute the first step toward making the equipment “production-ready” (technicians leave only after successful acceptance).
II.
Warranty and Repair
Warranty: 12 months (starting from the date of successful installation/commissioning; free parts and labor); Response: Remote diagnostics following a fault notification (4-hour initial response); on-site personnel dispatched for complex issues; Repair: Repair or replacement during the warranty period (at the seller’s discretion); Records: Service work orders and traceable maintenance logs—specifying the warranty period as starting from the “date of installation” rather than the “factory dispatch date” is more favorable to the buyer.
III. Spare Parts Supply
Rapid Shipment: Global spare parts dispatch within 48 hours (e.g., Changlin/Sinomach inventory of over 2,000 items); Local Warehousing: Spare parts depots in destination countries/regions (e.g., Zoomlion Europe’s multi-level network); Wear Parts: Stock maintained for common items like blades, belts, and seals; Supply Commitment: Parts availability for 8–10 years post-warranty—speed of supply determines downtime (48-hour dispatch is a key competitiveness indicator for machinery exports).
IV. Remote Support & IoT
24/7 Remote Support: Assistance via phone, WhatsApp, or WeChat video (e.g., e-shion’s 4-hour initial response time);
PLC Remote Diagnostics: IIoT gateways for remote parameter adjustment, troubleshooting, and software patching (reducing MTTR from days to minutes); Applications: Most 2026-model machines feature VPN remote access—remote diagnostics serve as the primary method for overseas service (eliminating the need to wait for engineers to fly in and preventing prolonged machine downtime).
V. Scheduled Maintenance & Upgrades
Preventive Maintenance: 12-month maintenance plan and checklist (scheduled servicing every 250–500 hours);
Field Visits: Regular follow-up inspections during the warranty period; Upgrades: Technical upgrade packages (e.g., IoT modules, efficiency optimizations); Trade-ins: Residual value exchange programs (offered by select manufacturers)—proper maintenance extends service life by 20–30% (adhering to the manufacturer’s maintenance schedule).
Overseas buyers prioritize after-sales service when purchasing machinery. Key standard offerings include installation and commissioning, training, a 12-month warranty, 48-hour spare parts dispatch, 24/7 remote support, and scheduled maintenance.
Remote diagnostics and local spare parts depots are significant value-adds for major exporters and should be explicitly included in contracts (covering response timeframes and parts supply commitments).
