The reason for the decline in the quality of the elevator installation is nothing more than:
1. In recent years, installation costs have decreased, and contracting costs have continued to decline.
Without proper profit, it is impossible to have good construction quality and after-sales service. In recent years, the installation cost of elevators has been calculated by the method of linking with the price of elevator products (generally 8% to 15%). Due to fierce market competition, the price of elevator products has been declining, and the installation fee has also been decreasing. The contracting cost on the head of the installer is only 400-500 yuan/layer, which causes a large loss of skilled workers (many people enter the maintenance market, resulting in a decrease in warranty costs, which aggravates the disorder of the maintenance market). Migrant workers carry out the installation. Because the basic quality of the installation workers is not high, and there is no good master to help, many of the fitter masters on the scene have not seen the rails, let alone use. Although it is a half-ticket (the commissioning is the responsibility of the company), many of the hard defects left behind are irreparable.
2. Elevator companies re-sale within the company, light installation services.
Elevator sales is the leader of all work in the enterprise. It is understandable to pay attention to sales. However, 1) sales personnel often disregard the actual situation and promise many requirements of Party A, but they cannot be honored during installation. Many contradictions are caused at the scene, which directly affects the relationship between Party A and Party B. , delay construction. 2) The management of the company has a heavy progress and light quality. For example, the XX company has a contract execution department and an installation and maintenance department. There is no department with quality management and no full-time quality inspector. The quality of the installation was completely led by the installation team, and the quality of the commissioning personnel was ineffective. The problem was found to be helpless, and only the common clearance was reached. 3) The project manager becomes a meeting manager. The project manager of the elevator company often manages one site for ten people. Every day, he is tired of meeting in Party A, and the meeting requirements are difficult to implement. The ×× construction site has 8 elevators. The project manager has only visited the site twice and has never been to the site. How to guide the work and be responsible for the project. 4) Elevator installation is a certain time guarantee. The sales staff promised that the company's delivery was slow, and the number of missing parts greatly delayed the installation and commissioning time. In addition, the construction site problems emerged endlessly, the hoistway could not be delivered on time, there was no water shortage, the parts were stolen, and so on. The elevator at the station dragged on for more than a month, and the actual operation time was only four or five days. “Seiko work is a rule of craftsmanship from ancient times to the present, especially the large-scale projects of the government. It is limited to a certain day of delivery. Elevator installation is the last link. It is often only a few days. It is really difficult to install the team. There is no need for time. Guaranteed that the quality of the installation is difficult to guarantee.
In response to the above situation, in order to improve and improve the installation quality, the electrical automation technology network puts forward the following suggestions:
(1) Elevator installation project is always part of the construction project. Installation is a kind of labor operation. It should also get rid of the current method of linking with the ladder price. This can solve the problem of blindly reducing the installation cost and the real protection. Vulnerable groups - the interests of the installation workers. There is no reliable Anvi quality without an amount of profit. To this end, we advocate returning to the elevator installation quota management billing method, and effectively incorporate this piece into the management scope of the construction project. According to the mode of other construction projects, the corresponding quotas for the fixed stations above the province (the current provinces and municipalities such as Beijing and Liaoning have been compiled), the quota is directly linked to the workload, technical content and local wage levels, adjusted annually, by the construction administration. The department is enforced below, at least first in the bidding project and then promoted. Thereby ensuring the necessary labor compensation for the construction project, stabilizing the installation team, and laying the necessary material foundation for improving the installation quality.
(2) Improving manufacturing quality is a necessary condition for improving the quality of installation.
If the manufacturing quality reaches a certain level, the installation quality is easy to control and stabilize at a good level. On the contrary, "first-class installation, second-rate manufacturing", on-site dynamic "moving fire", transformation of assembled elevators, the installation quality is inevitably low . In recent years, due to the sharp increase in production, big companies have been unable to keep up with the various links. They are wrong, missing, late, and cannot be delivered in stages. Some things that should have been done at the factory are also brought to the construction site. Do, this is also the reason for the decline in the quality of the installation. As for individual small factories, due to the rising prices of raw materials, the phenomenon of cutting corners and cutting materials is endless. The so-called "national procurement" is not the person who chooses the quality of the good, but who is cheaper, so how to ensure the quality, only improve the manufacturing quality, select better spare parts, can guarantee better Installation quality.
(3) Practically strengthen the acceptance of the installation quality of the elevator. Even if the installation quality of the elevator is installed, not the inspection, the acceptance of the inspection is extremely important to improve the installation quality. At present, this exclusive monopoly test does not fully comply with the spirit of Order 373. Only by introducing a competitive mechanism can the needs of the fully market-oriented elevator industry be met. For effective on-site testing, often due to the low level of personnel practice, the lack of experience in on-site installation and handling problems, and the guidance of improving the quality of installation, it is not necessary to talk about unhealthy trends in the industry. The acceptance and acceptance of work must adhere to the three-level management system of the team, enterprise and full-time testing, which are indispensable. Recently, Guangzhou Hitachi Elevator Co., Ltd. implemented the enterprise inspection responsibility to the maintenance department and implemented the handover acceptance system between the installation department and the maintenance department, which has an immediate effect on improving the installation quality. Shanghai Mitsubishi Elevator Co., Ltd. has always adopted a strict internal inspection system. The full-time inspectors of each branch have checked the construction quality of the agent installation team, thus ensuring that the overall installation quality is stable at a high level. Of course, we should respect the installation workers, respect their labor, give certain assistance in all aspects, and create more convenient conditions, so that the elevator installation work can be done quickly and well.
