Elevator parts under what circumstances should "retire"? The state does not have a clear rule on this. Since yesterday, the Beijing local standard "Technical requirements for the rejection of major elevator components" began to solicit comments on the website of the Municipal Quality Supervision Bureau. The formulation of the standard will not only change the status quo of the scrap of elevator parts without evidence, but also greatly promote the renovation process of the old elevator in this city.

It is understood that the use of elevator parts for many years of aging has become the main factor leading to elevator safety accidents, but in some residential areas, there is still the phenomenon of old elevator "over-age" work, some "old" parts of the operation buried the safety risks, but some communities are reluctant to replace in order to save money.

The draft for comments on the elevator traction drive, suspension device, car, counterweight, door system, safety protection, electrical control, guide rail, these eight categories of major safety components of the scrap put forward the basic technical requirements and basis, is a major safety risk of elevator parts scrap criteria. Take the car as an example, when the car wall, car top serious deformation, damage, car bottom serious deformation, cracking, rust, perforation, glass car wall cracks and other circumstances and can not be repaired should be rejected. The "door system" includes the floor door, car door, door machine, floor sash, etc., the standard proposes that the opening and closing time of the automatic door should not exceed 3.2 seconds, in addition, the deformation and damage of the floor sash will cause risks such as the floor and car door, and it is easy to produce falling, impact, extrusion and other dangers. Therefore, when these problems are unqualified and cannot be repaired, the elevator parts will also be disqualified.

Industry insiders said that after the introduction of the standard, the property units will take this opportunity to strengthen the supervision of the elevator and immediate maintenance and scrapping, property units and owners can also decide whether to scrap the elevator in accordance with this standard.
