Can elevator maintenance be tendered?

Elevator maintenance can be carried out through bidding. After inquiring the relevant information, the unit that needs to participate in the bidding must have the maintenance qualification. Elevator maintenance is generally carried out by the elevator manufacturing unit or entrusted by relevant departments. The elevator needs to be maintained, mainly to ensure the personal safety of the community owners, which can effectively ensure that the elevator can be used normally and will not be damaged. In addition, it is necessary to maintain the elevator regularly. Some accessories can be coated with lubricating oil, and the dust on the elevator needs to be removed in time. These are all professional maintenance work, which needs professionals to operate.
