    Now, if the elevator is very old, it needs to be scrapped and renovated. Then there will be some symptoms when the elevator is old. Many people will think that the elevator should be replaced if it lasts a long time. In fact, this is not the case. We still need to operate the elevator and some parts. Now let's see what symptoms will occur when the old elevator is discarded.

1、Status of use
    Whether the elevator needs to be repaired or replaced depends not on the time limit, but on the use of the elevator parts. At present, the state does not have a mandatory scrap standard for old elevators, but carries out risk assessment for old elevators in use. "Through the evaluation of risk sources, the assessment results can be divided into general maintenance, renovation and scrap replacement. For elevators with high risk and no renovation value, scrap replacement is needed.

2、Look at parts
    The elevator, like the main computer case, is an'assembly'. Chen Fengwang, secretary-general of National Elevator Standardization Technical Committee, said. In the new national standard, whether the elevator is scrapped or not is based on its "assembly parts". The technical conditions for scrapping of these components are also specified in detail, including mechanical damage, abnormal wear, rust, material aging, electrical failure, electrical component damage and other six failure or potential failure modes affecting safe operation. "If the problem of elevator parts is serious according to these technical conditions, the scrapping of the whole machine can be considered.

3、Transformation problem
    Generally, the old ladder transformation can be put on the agenda in more than 10 years. Overhaul is generally a remedy for the symptoms but not the root cause. It is not only the renewal and maintenance of the original elevator, but also the replacement of new parts, without changing the specifications and functions of the original elevator. The transformation is based on the original elevator to upgrade its functions, such as adding storeys, adding functions, changing specifications, changing systems, etc. That is to say, the elevator equivalent to the new specifications after the transformation needs to be re-checked and received the elevator qualification certificate. Overhaul refers to the replacement of the main engine, or wire rope, etc. Overhaul can not change the brand of the original elevator, but the transformation can change the brand of the original elevator.

    Now if the elevator is used for a long time, it will need to be scrapped. If it is scrapped, it will need to look at some symptoms. Many people do not know how to look at it. In fact, according to the use of elevators and components, we can see whether it is necessary to scrap the elevator or rebuild it. The above is the relevant content for you. Thank you for your observation.
