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.要定期在升降机链接销轴之间打磨润滑油，减少部件之间的磨损程度，降低噪音，可对事故的发生起到很好的预防作用。

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.卸下并拆开升降机下降阀，用压缩空气将柱塞吹净，然后装入，重新安上。检查所有的液压管道和接头。管道不能有破损，接头不能有松动，必需将所有接头拧紧。

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.液压油的油质和油位。升降机全程升起，在这位置时，液压地面应高出箱底 40～50 毫米。如发现液压油变暗、发粘或者有砂砾等异物，应及时更换（32＃液压油）。

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.定期检查液压升降机滚轮、中间轴及轴承，油缸销轴及轴承，臂架铰轴及轴承等有无磨损。

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

5.液压系统任何部位之间，必需卸压，以免压力油喷出，升降机工作台溘然下滑。

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.不得任意调整溢流阀。液压升降机系统中的每个元件都是在划定压力下工作的。任意调整溢流阀后，可能会造成液压系统非正常运转。

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.
