首先是上海升降平臺出現聲音異常，可能是升降平臺超載引起的，這時候的載解決方法是檢查舉升重量，再堅持是電機固定螺栓松動，還有可能滑塊處缺少潤滑油。Shanghai is the first of the lifting platform appeared abnormal sound, may be lifting platform caused by overload, load solution at this time is to check the weight lifting, and adhere to the motor fixing bolts loose, there may be a lack of lubrication oil slider.
 
其次是出現上海升降平臺不舉升的現象，可能是油中有空氣，解決方法是松開排氣螺釘，排出氣體后擰緊。還有可能是液壓油凝固，重新重新加注合格適合當時季節問題的的液壓油后即可解決。Followed by Shanghai lifting platform does not lift the phenomenon, there may be oil in the air, the solution is to loosen the exhaust screw, exhaust gas after tightening. There may be the solidification of hydraulic oil, re filling qualified for the time of the season after the problem of hydraulic oil can be resolved.

還要檢查各管件接頭是否擰緊油缸油封是否變形、翹曲導致液壓油滲漏，無法產生足夠壓力。另外上海升降平臺的泵站電機倒轉也是液壓升降平臺無法舉升的一個原因，這是與電機內電路圖對照，接線是否正確，可以導線試一下。But also to check whether the pipe fittings tighten the cylinder oil seal deformation, warping lead to hydraulic oil leakage, can not produce enough pressure. In addition, the pump station motor Shanghai lift pump is also a cause of the hydraulic lifting platform can not be lifted, which is compared with the motor circuit, wiring is correct, you can try to wire.

最后是上海升降平臺的電機損壞壞，更換電機保險絲斷限位開關壞，更換限位開關等。最后說的是液壓升降平臺出現外部漏油、滲油的情況。Finally is the Shanghai lifting platform motor damage is bad, replace the motor fuse off limit switch is bad, replace the limit switch, etc.. Finally said that the hydraulic lift platform outside the oil leakage, oil leakage situation.

一般情況下有少許的滲油是正常的。常用的解決方式有重新擰緊管件連接處、擰緊排氣閥、更換密封元件，另外還有可能是油量過多導致的溢出，這是可以從容器中適當減少油量。In general, there is a little oil seepage is normal. The commonly used solution is to re tighten the pipe fittings, tighten the exhaust valve, replace the sealing element, there may be too much oil caused by overflow, which is appropriate to reduce the amount of oil from the container.
