Selection Guide for Elevator Installation Unit

How to choose an installation company:

There are three points to consider when installing an elevator in an old building: 1. The quality of the product itself; 2. The installation quality; 3. The effect of later use and expenses.

The long-term use of common elevators is good or bad. Professionals in the elevator industry recognize the concept of "334", that is, 30% of the installation quality, 30% of the product quality, and 40% of the maintenance quality. Because China has long been a major elevator manufacturing country, the quality control of the elevator itself has little difference between manufacturers; the quality of the installation is directly related to the stability and comfort of the later use and the failure rate, and the installation of the track and other mechanical parts once there is a problem The later rectifications are difficult and costly.

The installation of elevators involves many projects, such as: geological survey, civil engineering, steel structure, decoration, elevator installation and debugging and other projects. Since the steel structure, foundation, etc. are installed and inspected, there are almost no follow-up maintenance problems. Only elevators Need to consider long-term quality and post-service. After installation, the elevator needs more than 20 years of safe use and maintenance. The ability of the maintenance service company and the level of employees are the basic conditions for the effect of the elevator maintenance service, so the choice of the elevator company is a very important link.

Since elevators are special equipment and elevator safety accidents often occur, the state enforces mandatory supervision of the elevator and elevator industry, which stipulates that the "installation, maintenance, and transformation" of elevators needs to be carried out by qualified elevator companies.

Therefore, the installation unit should be an elevator company with elevator "installation, maintenance, and transformation" qualifications, and only after signing an installation contract with a qualified high-quality elevator company, can they obtain effective later service guarantees.

How to guarantee after-sales service:

The quality of an elevator, in addition to its own quality and performance, is more important for after-sales service. The quality of after-sales service will directly affect the service life and use effect of the elevator, and directly affect the interests of the owner. Therefore, when signing an elevator installation contract, you must choose to sign an overall contract with a large company with elevator installation, maintenance, and transformation qualifications to ensure worry-free after-sales. Then the quality of elevator installation and after-sales service should be considered as the focus of elevator retrofit selection. Pay attention to the following points when inspecting elevator retrofitting:

First of all, the state stipulates that elevator companies must have valid elevator installation, transformation, and maintenance licenses to engage in elevator installation, transformation, and maintenance. Therefore, when choosing an installation company, first look at whether the installation company has its own qualifications, and it is necessary to extract Time to review and inspect the company, and require the company to produce relevant certification documents such as business license, corporate honor and bank credit; in-depth understanding of pre-sales and after-sales services; see the actual number of maintenance personnel on the job, the number of existing maintenance elevators, and service sites These points are the guarantee of the timeliness of elevator emergency rescue and fault handling; the three system documents of "ISO9001", "ISO14001" and "ISO18001" are the company's quality, safety and environmental management certified by international authorities The proof of the system is a sign that the service of the elevator installation company is relatively complete, standardized and sound. This can also be the focus of the inspection. Effective measures for maintenance companies to supervise and maintain on-site equipment and service personnel are important means to ensure the quality of maintenance, and a large maintenance service team can guarantee worry-free after-sales service. Others can be considered: special tools used for maintenance, vulnerable spare parts, delivery cycle, implementation of elevator functions, etc., can all be included in the inspection content, which directly reflect the comprehensive strength of the installation company.
