裝載機的潛在故障，是某些山東裝載機的故障在逐漸發(fā)展中，但尚未在裝載機的功能方面表現(xiàn)出來，而同時又接近這些故障萌發(fā)的階段，當(dāng)山東裝載機的這種情況能夠診斷出來時，即認(rèn)為是一種出現(xiàn)故障的現(xiàn)象，并稱為潛在故障。The potential fault in Shandong loader, some Shandong loader fault in the gradually development, but not in the loader function aspects, and at the same time close to the fault germination stage, when the Shandong loader can be diagnosed, that is a failure phenomenon, and said as a potential fault.

裝載機廠家舉例，例如山裝載機的零件在疲勞破壞過程中，其裂紋的深度是逐漸擴展的，同時其深度又是可以探測的。當(dāng)探測到山東裝載機某些部件的裂紋擴展的深度已接近允許的臨界值時，便認(rèn)為是存在潛在故障，必須按實際故障一樣來處理。For example, in the process of fatigue failure of the parts of the Shandong loader, the depth of the crack is gradually expanded, and the depth of the crack can be detected. When the depth of the crack extension of some parts of the Shandong loader is close to the critical value, it is considered to be a potential failure.

及時的探明了裝載機的潛在故障，就有可能在小型裝載機達到功能故障之前進行排除，這有利于保持山東裝載機完好狀態(tài)，避免由于發(fā)生功能故障而可能帶來的不利后果，這在山東裝載機的使用維修實際中具有重要意義。裝載機廠家提醒，一定要注意好這些問題。Time proved the potential failure of Shandong loader, it is possible to exclude prior to failure in small loaders, which helps maintain the Shandong loader intact, avoid due to malfunction and the possible adverse consequences, which has important significance of loader used in Shandong maintenance practice. Loader manufacturers to remind, be sure to pay attention to these problems.
