  During the designated period of maintenance for China passenger elevators, the inspection, refueling, dust removal, and debugging of safety devices is performed on the elevator components in operation. Including non-destructive testing and lubrication maintenance of elevator traction wire ropes. So what problems should we pay attention to during elevator maintenance? Let's take a look together.

  mechanical part:

  1. The traction machine of the elevator needs oil lubrication. There are two scales of the outer cover of the traction machine. Open the oil nozzle to check that the oil should be in the middle of the two scales. If the oil is lower than the lower scale, it means that the traction machine should be refueled. If the oil is not refueled, the elevator will run for a long time. It will not be well lubricated, resulting in the burnout of the elevator traction machine and motor. After the elevator has been running for a long time, the oil should be replaced in time to keep the traction machine always fresh and well lubricated.

  2. Cleaning and lubrication of elevator car guide shoes. Everyone knows that the guide shoe runs on the guide rail, and there is an oil cup on the guide shoe. To prevent the elevator from generating friction noise, the oil cup must be regularly oiled and the guide shoe must be cleaned.
