Method for maintaining the wear of hydraulic elevators

Long term use of hydraulic elevators can lead to wear and tear. So, what are the methods for maintaining the wear and tear of hydraulic elevators? Let's take a look together! I hope it will be helpful to everyone.

Regularly polish lubricating oil between the connecting pins of hydraulic elevators to reduce wear and noise between components, which can play a good preventive role in the occurrence of safety accidents. Remove and disassemble the hydraulic 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.

The quality and level of hydraulic oil. The hydraulic lift 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. Regularly inspect the roller, intermediate shaft, and bearings of the hydraulic elevator, as well as the pin shaft and bearings of the oil cylinder, and the hinge shaft and bearings of the boom for wear. Any part of the hydraulic system must first be depressurized to prevent pressure oil from spraying out and the hydraulic elevator workbench suddenly sliding down.
