Elevator installation and maintenance, engaged in elevator installation and maintenance, what docume

Elevator is a special industry, and it takes at least one year to do the qualification, and it costs at least tens of thousands of yuan. Maintenance is mostly related to machinery, such as changing the oil in the machine room, door machine failure (to go down the shaft), more dangerous, the data of the State Supervision Bureau, more than 6 percent of the elevator injury accidents are all elevator workers. Of course, maintenance will also involve PLC such as the program replacement of elevator inverter, which will not be programmed by each manufacturer, and you only bring special tools to enter the program or manually programme.

The time and frequency of work are related to the company, and the company with a large business is naturally more, generally speaking, the normal maintenance of an elevator is twice a month, and the emergency repair is not counted.

Generally, there will be no accommodation, and the salary is average, between 1000 and 3000, of course, some places may be higher, but the profits of the entire industry are not high, so the treatment is naturally not high, and it belongs to the lower middle. If you really want to do maintenance, it is recommended to go to the subway or the property of the unit to do it, and the treatment is better. Or do PLC development in the R&D department of the elevator factory.

I advise you to think carefully and hope it can help you.

Hello, I am the assistant manager of a company, I have relatively more contact with elevator things, and I often deal with people in elevator companies. As for what you said about the installation and maintenance of elevators, there is a lot of business, depending on what you want to do. Simply put, the danger of this work is relatively large, high-altitude work, and it is mechanical, large-scale, and the risk factor is larger than that of ordinary people.

Even high-level personnel, such as managers, generally do the actual operation, which is quite hard. The other ones are other business (clerical) of the elevator, which is more relaxed, but that is not a business, and the salary must be relatively low. So, if you have a choice, try not to do this industry, thank you!

My brother learned elevators.

But that thing is really a bit dangerous, and he works as an elevator worker, which is to install elevators. Physical strength is also required. Money?

Generally. The monthly salary is only 2000. Also score in what city to work in.

If you want to make a fortune with a future, then also; Don't learn that.

To engage in elevator installation and maintenance business, individuals need to hold special equipment operation certificates, but individuals cannot undertake maintenance business, and must contract business with units.

Elevator maintenance workers must hold a special equipment operation certificate before they can take up their posts.

All units engaged in the installation, transformation, maintenance and daily maintenance of elevators and other mechanical and electrical special equipment (hereinafter referred to as mechanical and electrical special equipment) (hereinafter referred to as construction units) must obtain the "Special Equipment Installation, Transformation and Maintenance License" and engage in corresponding work within the scope of the license.

According to the relevant provisions of the special equipment regulations: only three types of institutions can be engaged in elevator maintenance. 1. Elevator manufacturing plant; 2. Elevator installation company; 3. Elevator maintenance unit.

Individuals cannot undertake maintenance business. The scale of applying for the establishment of the above-mentioned institutions is different, and the cost is naturally different. At the same time, among the conditions for the establishment of the above-mentioned institutions, there are corresponding personnel structure requirements.

Among them, there will be a certain number of installation and maintenance personnel, these personnel should have the corresponding special equipment operator qualification certificate, and all the costs related to personal certification are about 1500-3500 yuan. After obtaining the qualification, you can install, repair and maintain in one of the above-mentioned institutions, but you cannot contract maintenance business in your own name.

1) Machine room: power distribution control panel emergency stop switch, thermal relay, speed limiter switch. (2) Shaft:

Upper limit switch and lower limit switch (some elevators put these two switches in the safety loop, and some use these two switches to directly control the power supply). (3) Pit: broken rope protection switch, pit emergency stop switch, buffer switch.

4) In the car: control box emergency stop switch. (5) Car roof:

Safety window switch, safety gear switch, car roof maintenance box emergency stop switch. 3.Fault stateWhen the elevator is in a stopped state, all signals can not be registered with the computer, and the elevator cannot operate, so it is necessary to suspect that it is a safety loop failure.

At this time, you should go to the control screen of the computer room to check the status of the safety relay. If the safety relay is in the released state, it should be judged as a safety loop fault. The possible causes of the failure are as follows.

1) There is a lack of phase in the input power supply, which causes the phase sequence relay to operate. (2) Elevator thermal relay action. (3) The speed limiter overspeed causes the speed limiter to switch on and off.

4) The elevator rushes to the top or sinks to the bottom to cause the limit switch action. (5) Pit broken rope switch action. (6) Safety gear action.

7) The safety window is lifted by someone, causing the safety window to open and close. (8) The emergency stop switch may be pressed. (9) If each switch is normal, check whether the contact contact is good, whether the wiring is loose, etc.

In addition, at present, although the safety circuit of many elevators is normal, and the safety relay is also engaged, but usually the auxiliary normally open contact is taken on the safety relay and then sent to the computer or PC for testing, so the failure of the computer itself will also cause the failure of the safety loop.

Elevator doors put things are clamped and stopped.
