More capable of exerting greater power when working! With the increasing frequency of use of hydraulic elevators, attention needs to be paid to the maintenance and repair of vulnerable parts. The so-called "sharpening does not affect the normal use of wood" does not affect normal use, and it is necessary to always do a good job in the maintenance and repair of vulnerable parts. Below, the manufacturer of lifting cargo elevators will introduce the maintenance methods for everyone:

1.要定期在升降機鏈接銷軸之間打磨潤滑油，減少部件之間的磨損程度，降低噪音，可對事故的發生起到很好的預防作用。

1. Regularly polish lubricating oil between the elevator link pins to reduce wear and noise between components, which can play a good preventive role in the occurrence of safety accidents.

2.卸下并拆開升降機下降閥，用壓縮空氣將柱塞吹凈，然后裝入，重新安上。檢查所有的液壓管道和接頭。管道不能有破損，接頭不能有松動，必需將所有接頭擰緊。

2. Remove and disassemble the elevator lowering valve, blow the plunger clean with compressed air, then install it and reinstall it. Check all hydraulic pipelines and joints. The pipeline must not be damaged, and the joints must not be loose. All joints must be tightened.

3.液壓油的油質和油位。升降機全程升起，在這位置時，液壓地面應高出箱底 40～50 毫米。如發現液壓油變暗、發粘或者有砂礫等異物，應及時更換（32＃液壓油）。

3. The oil quality and level of hydraulic oil. The elevator should be raised throughout the entire process, and at this position, the hydraulic ground should be 40-50 millimeters higher than the bottom of the box. If the hydraulic oil becomes dark, sticky, or has foreign objects such as gravel, it should be replaced in a timely manner (32 # hydraulic oil).

4.定期檢查液壓升降機滾輪、中間軸及軸承，油缸銷軸及軸承，臂架鉸軸及軸承等有無磨損。

4. Regularly inspect the hydraulic elevator rollers, intermediate shafts and bearings, oil cylinder pins and bearings, boom hinge shafts and bearings for wear.

5.液壓系統任何部位之間，必需卸壓，以免壓力油噴出，升降機工作臺溘然下滑。

5. Any part of the hydraulic system must first be depressurized to prevent pressure oil from spraying out and the elevator workbench suddenly sliding down.

6.不得任意調整溢流閥。液壓升降機系統中的每個元件都是在劃定壓力下工作的。任意調整溢流閥后，可能會造成液壓系統非正常運轉。

6. Do not adjust the overflow valve arbitrarily. Each component in the hydraulic elevator system operates under a specified pressure. Arbitrary adjustment of the overflow valve may cause abnormal operation of the hydraulic system.
