If the elevator is very old, it needs to be scrapped and remodeled. Then there will be some symptoms when the elevator is old. Many people think that the elevator should be replaced if it takes a long time. In fact, this is not the case. We still need to open the elevator and some parts. Let's take a look at the symptoms of the old elevator when it is scrapped.



1. The status of use
Whether the elevator needs to be repaired or replaced does not depend on the time limit, but depends on the usage status of each part of the elevator. At present, the country does not have a mandatory scrapping standard for old elevators, but a risk assessment of old passenger elevators in use. "The evaluation results are formed through the evaluation of risk sources, which are divided into general maintenance, renovation and scrap replacement. For elevators that are at great risk and do not have the value of renovation, they need to be scrapped and replaced.





2. Look at the parts
The elevator is an ‘assembly’ like the main computer box. "Said Chen Fengwang, secretary general of the National Standardization Technical Committee for the top ten elevator brands. In the new national standard, whether the elevator is scrapped is based on its "assembly parts." Damage, abnormal wear, corrosion, material aging, electrical failure, electrical component damage and other 6 failures or potential failure modes that affect safe operation. "If the elevator components are judged to be serious according to these technical conditions, the whole machine can be considered scrapped.



3. Transformation issues
Generally more than 10 years can be put on the agenda for the renovation of the old ladder. Overhaul generally treats the symptoms but not the root cause. It is an update and maintenance on the basis of the original elevator and replacement of new parts and components without changing the specifications and functions of the original elevator. Reconstruction is a functional upgrade on the basis of the original elevator, such as adding landings, adding functions, changing specifications, replacing systems, etc., that is, an elevator with a new specification after the transformation needs to be re-accepted and obtained an elevator certificate. Overhaul refers to the replacement of the main engine, or the steel wire rope, etc. The overhaul cannot change the brand of the original elevator, but the renovation can change the brand of the original elevator.

Now the elevators need to be scrapped after they have been used for a long time. If they are scrapped, they also need to see some symptoms. Many people don't know how to look at them. In fact, you can see whether the elevator needs to be scrapped or remodeled according to the usage of the elevator and the usage of the components. The above is the relevant content for everyone. Thank you for watching.
