All construction machinery has normal wear part consumption during long-term operation. Overseas customers face long logistics distances, long transportation cycles and high emergency replenishment costs. Once core wear parts are damaged and cannot be replaced in time, equipment will shut down and delay construction progress. Many overseas buyers purchase spare parts on demand, which is inefficient and easy to cause project delays. Pre-storing common wear parts according to equipment model, working intensity and service duration can quickly deal with daily wear failures and avoid shutdown waiting. Scientific parts planning guarantees long-term stable operation and reduces economic losses caused by equipment idling.
