液壓升降機各個部件都極其重要，不管哪一個部件出了問題，都會影響升降機的運行與可靠性，如果升降機升不起來我們該怎么辦，或許還有很多人不了解。

Each component of a hydraulic elevator is extremely important. No matter which component goes wrong, it will affect the operation and safety reliability of the elevator. If the elevator cannot be lifted, what should we do? Perhaps there are still many people who do not understand.

1、當液壓升降機超負荷運行時，會升不起來，這主要是因為每臺升降機都有自己的額定載重量，一旦超載起升，就會出現起升無力或升不起來的現象。所以這時好的辦法就是保證裝卸貨物時不能超載。

1. When hydraulic elevators are overloaded, they will not be able to lift, mainly because each elevator has its own rated load capacity. Once overloaded, there will be a phenomenon of weak lifting or inability to lift. So the good solution at this point is to ensure that the loading and unloading of goods cannot be overloaded.

2、設備的回油閥如果沒有關閉也會導致其升不起來，此時可以采用旋緊回油閥的辦法來解決。

2. If the return valve of the equipment is not closed, it may also cause it to not rise. In this case, the method of tightening the return valve can be used to solve the problem.

3、當設備的手動泵單向閥卡死導致回位失靈也會升不起來，對此可以旋開油泵閥口螺栓，進行進一步的檢修、清洗以及更換清潔液壓油來解決。

3. When the one-way valve of the manual pump of the equipment is stuck and causes the return valve to malfunction, it may not be able to rise. To solve this problem, the oil pump valve port bolt can be loosened, further maintenance, cleaning, and replacement of clean hydraulic oil can be carried out.

4、可以是由于設備的手動泵、齒輪泵嚴重漏油引起的，這是可以正確更換油泵密封圈來解決。

4. It can be caused by severe oil leakage from the manual pump and gear pump of the equipment, which can be solved by replacing the oil pump sealing ring correctly.

5、可能是由于設備齒輪泵損壞，而無壓力進行升降，好的辦法是更換齒輪泵。

5. It may be due to damage to the gear pump of the equipment, and there is no pressure for lifting. A good solution is to replace the gear pump.

6、在設備液壓油不足時也會導致不升降，這是只需要加足液壓油就可以運行。

6. When the hydraulic oil of the equipment is insufficient, it can also lead to non lifting, which only requires sufficient hydraulic oil to operate.

7、如果設備的電路斷路也不進行升降，此時需要檢查保險絲進行檢修更換等來解決。

7. If the circuit of the equipment is open and the lifting is not carried out, it is necessary to check the fuse for maintenance and replacement to solve the problem.
