The door linkage switch installed in the elevator door, due to the dust in the well road, the humid environment, and the daily on-off, generate oxides, which may easily cause poor contact and affect the normal operation of the elevator. In the daily maintenance process, the maintenance staff can easily ignore the maintenance of the door switch contacts, and the maintenance personnel are accustomed to only bring a towel. After cleaning the device, the towel has been stained with stains, and then it is not appropriate to clean the switch contacts. Special attention should be paid to the maintenance of the door switch contacts.

According to the normal situation analysis, the wire rope replacement cycle is 6 to 9 years, and the traction sheave is 6 to 12 years. Under the circumstance of maintenance and maintenance, the buffer and guide rail are basically 30 to 40 years, and the traction motor is 20 to 30 years. . The most frequent daily replacement is the lower door slider, door switch and electrical accessories. The reason for the damage of the lower door slider is normal friction and wear caused by dust accumulation in the door slot. The reason for the damage of the door switch is caused by oxidation on the switch contact. Poor contact, and the root cause of oxidation is that the contacts are not clean and uneven, so strengthening the cleaning of daily small parts can effectively reduce equipment damage and extend the service life of equipment (or accessories).

Based on the above analysis, we can see the importance of equipment maintenance, just like a person, congenital physical condition is good, if you do not strengthen the exercise of the day after tomorrow, the body may not be as good as a congenital physical condition, and the person who insists on exercising the day after tomorrow . Therefore, as the equipment manager strengthens the safety management concept, it is actually implementing the maintenance of equipment and facilities, in order to truly extend the service life of equipment and facilities for our owners, and ensure the preservation and appreciation of the property.
