Export construction machinery faces multiple challenges including transoceanic transportation, temperature differences and salt fog erosion. Tiny factory flaws will evolve into serious failures during shipping. Many overseas customers encounter pipe leakage, loose parts and damp circuits after receiving goods, resulting in delayed project start-up and extra maintenance costs. Standard pre-shipment quality inspection includes no-load and load test operation, pipeline tightness detection, fastener re-inspection, circuit moisture-proof test and appearance protection check, eliminating potential hidden dangers in all aspects. For overseas buyers, complete pre-shipment inspection is an important criterion for selecting reliable equipment and avoiding receiving risks.
