▶ Concept of maintenance -
The maintenance of the elevator refers to all activities such as preventive maintenance and repairs such as daily inspection and regular inspections to ensure that the elevator is safely and normally used for a given life.
▶ Necessity of maintenance -
In general, elevators are operated by a number of unspecified users without a driver, so a separate maintenance system is required to maintain the performance of the device. In particular, various safety devices such as wire rope door switches, door interlocks, brakes, and governors occur. If not prevented, it will cause a safety accident, so maintenance is indispensable for the safety of users. Therefore, in order to prevent human damage and property loss due to the operation of the elevator, partial repairs and modifications, including maintenance of
electrical and mechanical performance, should be made in a timely manner.
