Frequent Equipment Quality Hazards and Slow After-sales Response

Content: Screen suppliers through “three inspections” before procurement: inspect qualifications (suppliers must have ISO 9001 quality management system certification, national mandatory product certification (CCC), and additional Special Equipment Manufacturing License if the equipment is a special device); inspect reputation (check the complaint rate in the past 2 years through industry associations and customer review platforms such as Tianyancha and Qichacha, and give priority to brands with a complaint rate of <1%); inspect production capacity (conduct on-site inspections of the factory production line to ensure the annual production capacity can cover the purchase volume and avoid quality degradation due to insufficient production capacity). Specify a “three-dimensional response mechanism” in the after-sales agreement: respond to phone/online inquiries within 2 hours, send technical personnel to the site for general faults within 24 hours, and arrive at the site for major faults (e.g., equipment failure to start) within 48 hours (for remote areas, spare parts warehouses should be set up in nearby cities in advance to shorten the spare parts transportation time). During equipment acceptance, cooperate with a third-party testing institution (e.g., a testing unit designated by the China Construction Machinery Industry Association) to conduct 100% full-item testing in accordance with national standards, focusing on testing safety performance (such as braking systems and overload protection) and core parameters (such as operation accuracy and energy consumption). The equipment can only be signed for acceptance if it passes the test; if it fails, the supplier is required to replace or rectify it unconditionally. At the same time, keep the test report as legal evidence for subsequent after-sales rights protection.
