In order to further strengthen the management of elevator maintenance units, improve maintenance quality, reduce elevator failures, and prevent elevator accidents, the Municipal Market Supervision Commission commissioned the Municipal Special Equipment Safety and Energy Conservation Association to organize experts through government bidding to conduct on-site spot checks on the maintenance work of some elevator maintenance units in this city.

The scope of this spot check covers all administrative regions of the city, with a total of 650 elevators inspected, involving 238 elevator maintenance units. The focus of the spot check is on elevators in public gathering places, residential communities, and management units that have been in use for more than 5 years, where safety work is not actively implemented, there have been multiple failures, negative media coverage, and complaints and reports. The spot check adopts the method of "four no two straight, on-site surprise inspection", with the safety of the elevator equipment body as the center. A comprehensive evaluation is carried out from the aspects of elevator equipment operation status, maintenance technology level, elevator fault emergency rescue, etc., and the quality level of maintenance for each inspected elevator is determined.

Three maintenance units with a comprehensive quality level of 5 for single elevator maintenance discovered during spot checks, as well as four maintenance units with a comprehensive quality level of 4 and a comprehensive score rate below 80% for single elevator maintenance, will be criticized and given 12 points in a lump sum according to relevant regulations. Starting from 2019, the three elevator maintenance units that have been notified and certified by this city will be included in the annual post certification supervision and spot check enterprise name database, and the post certification supervision and spot check efforts will be strengthened. Starting from 2019, the proportion of annual elevator maintenance quality spot checks for the seven maintenance units mentioned above has been increasing year by year.

The Municipal Market Supervision Commission requires that all randomly inspected elevator maintenance units should conduct a comprehensive inspection of all elevators maintained by their own units in a timely manner, eliminate accident hazards in a timely manner, comprehensively regulate maintenance behavior, and improve the quality of elevator maintenance. Market supervision departments at all levels should further strengthen the daily supervision and inspection of elevator maintenance units within their jurisdiction, especially the inspection of maintenance elevators of notified units. Any illegal and irregular behaviors found during on-site inspections must be strictly investigated and dealt with in accordance with the law. Each inspection agency should include the relevant issues discovered during this random inspection in the key verification and verification content of elevator inspection, and strictly control the quality of the inspection.
