As a common tool for high-altitude operation, hydraulic cargo elevator has the characteristics of high efficiency, good safety performance and simple operation. It will encounter faults occasionally in the process of operation. In order not to delay everyone's use, we should master some maintenance common sense. Let's briefly talk about the common faults.

1.升高不到設(shè)定定高度，這種情況要檢查油箱內(nèi)的液壓油是否達(dá)到標(biāo)準(zhǔn)容量，檢查油箱是否漏油，如果液壓油不夠，請(qǐng)?zhí)砑?2#液壓油，這種在五金店都會(huì)有。

1. If it cannot be raised to the set height, check whether the hydraulic oil in the oil tank reaches the standard capacity and whether the oil tank leaks oil. If the hydraulic oil is not enough, please add 32# hydraulic oil, which can be found in hardware stores.

2.液壓升降貨梯存在靜電，導(dǎo)致不上升或者不下降，是因?yàn)樵诮泳€(xiàn)的時(shí)候沒(méi)有接地線(xiàn)，使液壓升降機(jī)帶靜電導(dǎo)致電箱失靈，可以用鐵制品觸地即可。

2. There is static electricity in the hydraulic lift cargo elevator, which leads to no rise or fall, because there is no grounding wire during wiring, which makes the hydraulic lift with static electricity, resulting in the failure of the electric box. You can touch the ground with iron products.

3.只能上升，不能下降：檢查電磁閥指示燈是否亮，按電箱上的下降鍵，如果電磁閥上燈不亮，則檢查電磁閥兩線(xiàn)是否斷路或者松掉。

3. It can only rise but not fall: check whether the indicator light of the solenoid valve is on, and press the down key on the electric box. If the indicator light of the solenoid valve is not on, check whether the two wires of the solenoid valve are open circuit or loose.

4.升降在起步時(shí)能正常上升，升降到一半時(shí)不能升降：一種是起動(dòng)電容損壞，二種是液壓油箱油量不足。

4. The lifting can rise normally when starting, but not when half of the lifting: one is that the starting capacitor is damaged, and the other is that the oil volume of the hydraulic oil tank is insufficient.

5.如果油管漏油，檢查對(duì)接口是否損壞，檢查O型密封件是否損壞，更換密封件或者是整體更換對(duì)接口。

5. If the oil pipe leaks oil, check whether the mating interface is damaged, check whether the o-seal is damaged, replace the seal or replace the mating interface as a whole.

6.在升降的時(shí)候上下顫抖，抖動(dòng)：檢查滑槽內(nèi)是否有小顆粒，垃圾，滑槽內(nèi)潤(rùn)滑油是否還有，沒(méi)有請(qǐng)及時(shí)添加否則，長(zhǎng)時(shí)間磨損導(dǎo)致升降機(jī)卡住損壞。

6. Shake up and down when lifting: check whether there are small particles and garbage in the chute and whether there is lubricating oil in the chute. If not, please add it in time. Otherwise, the elevator will be stuck and damaged due to long-term wear.

7.陰雨天氣不升降，請(qǐng)檢查上升電箱面板是否有潮濕：請(qǐng)用電吹風(fēng)吹干即可。

7. If it does not rise or fall in rainy weather, please check whether the panel of the rising electric box is wet: Please dry it with an electric hair dryer.

8.液壓升降貨梯的升降自落，升降自升：檢查電磁閥內(nèi)是否有垃圾，如有用汽油清洗或者用氣槍吹掉即可。

8. Automatic lifting and lowering of hydraulic cargo elevator: check whether there is garbage in the solenoid valve. If it can be cleaned with gasoline or blown off with an air gun.
