AGREED Head of the labor protection service Head of the structural (labor protection specialist of the unit (developer) or the specialist who is charged with these duties) (signature) (surname, initials) __________ _____________________ (signature) (surname, initials)

Today there are a lot of professions related to electrical engineering. But it must be admitted that the level of requirements for the performer in these professions is very different.

As an example, we can cite well-known electricians who serve some household or office buildings and are mainly engaged in replacing light bulbs. And they can be opposed by specialists who carry out the repair of complex equipment, which includes power electronic converting equipment. Both those and others - on the "you" with electricity, have an electrical safety approval group (perhaps even the same). Both are skilled workers.

But even on a superficial examination, the differences in the qualifications of these specialists are visible to everyone. With all due respect to the ZhEK electricians, electricians who diagnose and repair complex electromechanical devices are far from them in a professional sense.

So, in the "hierarchy" of electrical specialists electricians for the maintenance of modern cranes occupy a place close to the top. Without any exaggeration.

The days when the asynchronous drive of electric hoisting machines was started up by direct connection to the network are long gone. Today, only low-power girder drives are turned on in this way. And they are gradually moving to more progressive (read - more complex) drive systems.

Rheostat starting of an electric drive using motors with phase rotors is also a thing of the past. The overwhelming majority of cranes manufactured today are equipped with electric drives of the "frequency converter - asynchronous squirrel cage motor" system. In cab-operated cranes, all available drives are increasingly equipped with this system. Moreover, this applies equally to domestic and foreign cranes.

The advantages of such a drive system are higher energy performance, the possibility of realizing almost ideal smooth starting and braking, the complete absence of jerks and shock loads on the mechanical elements of the drive. Anyway, the control possibilities of a variable frequency drive seem almost limitless.

The possibilities are endless, but their use requires high qualifications, knowledge not only in the field of electric drive, but also in the field of electronics.

The crane is an object of increased danger during operation. Hence - a large number of all kinds of locks and protections included in schematic diagram control circuits of any crane. And the greater the lifting capacity of the crane, the more complex the circuit of its control circuits.

Not every electrician is able to understand the schemes of large special lifting machines. In addition, most modern cranes are equipped with microprocessor-based safety devices, the periodic maintenance of which and checking with test weights also often fall on the shoulders of crane service technicians.

So, let's note that in order to be an electrician for repairing cranes, you must:

2. Have an idea of ​​the work of microprocessor and network devices, be familiar with computer science;

3. Be familiar with the norms not only of the PUE and PTEEP, but also of a number of other documents regulating the operation of hoisting machines. Among these documents, in particular, PB-382-00, RD 10-208-98 and others.

4. Know not only electrical engineering, but also mechanics, since each crane drive is an electromechanical device. And without the knowledge of mechanics, it will be extremely difficult to set up this drive.

5. Become familiar with the training course "Electric Machines" at least at a level that allows, if necessary, recall the characteristics of electric motors.

6. Do not be afraid of heights and poor working conditions. Cold, wind (within the permissible wind load for this crane) - all this does not wait until you complete the repair and maintenance of the hoisting machine.

7. Have the skills to work safely with electricity and work at height.

8. Be in good health. After all, even low vision for doctors is a formal reason to deny a person the right to perform work at his best. And even glasses won't help here.

Obviously, not everyone can be a crane electrician. Here, one should only make a reservation that such requirements should be made only to specialists working at enterprises with a large and regularly updated fleet of lifting equipment. And there are plenty of such enterprises today.
