Hydraulic lift is one of many types of lifts, and it is widely used. When choosing the manufacturer of hydraulic elevator, we must be careful. If you choose a manufacturer with poor production quality, there may be many problems in the use process. The hydraulic lift should be operated by professionals. For newcomers who are not very familiar with this aspect but are simply trained, the operation is still a little difficult, and there may be some situations in the use process. For example, if the elevator can't rise, how should we deal with it? First of all, we should analyze the specific reasons, and the treatment methods are different for different situations.

一、負(fù)載物品過(guò)重。因?yàn)槊颗_(tái)升降機(jī)都有自己的噸數(shù)限制，如果物品的重量太高的話，就有可能出現(xiàn)起升無(wú)力升不起來(lái)的情況。如果是屬于這樣的情況，就應(yīng)該減少物品負(fù)重，然后再嘗試一下是否可以升的起來(lái)。

1、 The load is too heavy. Because each elevator has its own tonnage limit, if the weight of the goods is too high, it may be unable to lift. If this is the case, you should reduce the load of the object, and then try to see if it can rise.

二、回油閥沒(méi)有關(guān)閉，這樣的情況應(yīng)該及時(shí)旋緊回油閥。

2、 If the oil return valve is not closed, tighten the oil return valve in time.

還有一種情況是屬于回位失靈的情況?；匚皇ъ`有可能是由于手動(dòng)泵單向閥卡死。這時(shí)候就應(yīng)該將油閥閥門(mén)螺栓旋轉(zhuǎn)開(kāi)，進(jìn)行故障的檢修。如果卡死是由于液壓油，需要更換的就一定要及時(shí)進(jìn)行更換。

There is also a case of return failure. The return failure may be due to the jamming of the check valve of the manual pump. At this time, the oil valve bolt should be rotated open for troubleshooting. If the jamming is due to hydraulic oil, it must be replaced in time if it needs to be replaced.

還有可能是由于齒輪泵出現(xiàn)了損壞，改善升不上去的情況應(yīng)該對(duì)受損的齒輪泵進(jìn)行更換。

It is also possible that the gear pump is damaged, and the damaged gear pump should be replaced to improve the situation that it cannot be lifted.

五個(gè)原因，手動(dòng)泵齒輪泵出現(xiàn)嚴(yán)重漏油的情況。

There are five reasons: the gear pump of manual pump has serious oil leakage.

六、一定要加足液壓油在進(jìn)行啟動(dòng)，如果加足不足，也有可能出現(xiàn)升降階升不起來(lái)的情況。

6、 Be sure to add enough hydraulic oil before starting. If it is insufficient, the lifting step may not rise.

七、出現(xiàn)電路斷路。這時(shí)候就應(yīng)該請(qǐng)人員進(jìn)行檢查，要檢查保險(xiǎn)絲還有按鈕接觸器。

7、 There is an open circuit. At this time, professionals should be invited to check the fuse and button contactor.

八、也有可能是因?yàn)闉V清器出現(xiàn)了堵塞的情況，這時(shí)候就應(yīng)該清洗或者予以更換。

8、 It is also possible that the filter is blocked, so it should be cleaned or replaced at this time.
