Under what circumstances should elevator parts "retire"? The state does not have a clear regulation on this. Since yesterday, the draft of Beijing’s local standard "Technical Requirements for Elevator Main Components Scrap Judgment" began to solicit public opinions on the website of the Municipal Bureau of Quality Supervision. The formulation of this standard will not only change the status quo that there is no basis for the scrapping of elevator components, but also will greatly promote the renovation process of old elevators in this city.

It is understood that the aging of elevator product parts for many years has become the main factor leading to elevator safety accidents, but in some residential communities, there are still the phenomenon of "overage" work of old elevators, and the operation of some "aged" parts has buried safety Hidden danger, but some communities have been reluctant to replace them in order to save money.

The draft for comments puts forward the basic technical requirements and basis for the judging of 8 major safety components of elevator traction drive, suspension device, car, counterweight, door system, safety protection, electrical control, and guide rail. Criteria for scrapping of elevator components with significant safety risks. Take the car as an example. When the car wall and roof are severely deformed or damaged, the car bottom is severely deformed, cracked, corroded, perforated, or the glass car wall is cracked and cannot be repaired, it shall be deemed as invalid. The "door system" includes landing doors, car doors, door operators, sills, etc. The standard proposes that the opening and closing time of the automatic door in the center should not exceed 3.2 seconds. In addition, the deformation and damage of the sill will cause the floor and car doors to fall off. Risks such as grooves, which are prone to dangers such as falling, hitting, and crushing. Therefore, when these problems are unqualified and cannot be repaired, the elevator components will also be judged to be scrapped.

According to industry insiders, after the introduction of the standard, each property unit will take this to strengthen the supervision of elevators and immediate maintenance and scrapping. Property units and owners can also decide whether to scrap elevators according to this standard.
