The locksmith profession is predominantly male. To obtain it, you do not need to have a higher education; a secondary vocational education will be sufficient. Few enterprises, the work of which depends on the serviceability of production equipment, can do without technical specialists, in particular a mechanic for its repair.

This determines the advantages of this specialty: the presence of stable wages at the average level, or above it, constant demand in the labor market. In addition, by improving his qualifications, a mechanic can achieve a better position, initially increasing his ranks, and then becoming a manager.

List of duties performed

The nature of the tasks solved in the work process depends on the rank of the employee and his specialization. So in plumbing, the level of qualification is indicated by the assigned rank. It depends on the level of practical knowledge and experience. There are six of them in total, where the easiest tasks are performed by first-class repairmen. In some workshops that use pilot and experimental equipment, it is possible to assign the 7th and 8th category.

Such qualification as a rolling stock repairman deserves special attention. These specialists work not just with production equipment, machines and machines. A rolling stock repairman repairs cars and locomotives, as well as troubleshooting their parts and eliminating detected faults.

The tasks that repairmen of industrial equipment, machine tools and other things perform in the course of their professional activities are somewhat different. Their activities are more narrowly focused, focused on servicing machines and mechanisms of a certain type.

Tasks solved by rolling stock repairers and requirements for them

Those candidates applying for the position of rolling stock mechanic must be physically resilient and have the following knowledge and skills.

• A specialist must understand the general principle of the design and manufacture of cars and locomotives, as well as their individual parts.
• It is necessary to have knowledge about the methods and methods of checking the serviceability of elements and parts of rolling stock.
• It requires skills to restore parts that have been subjected to mechanical and physical wear.
• The specialist must have knowledge of the purpose and characteristics of liquids intended for washing and lubrication of components and assemblies.

Based on the required knowledge, it is possible to determine the nature of the work and the operations performed by the rolling stock repairman.

It is important that a worker involved in the maintenance and repair of locomotives and carriages and their elements must have good vision and hearing. And also have flexible hands. Such requirements are formed from the specifics of the work processes being performed.

Just like industrial equipment mechanics, rolling stock repairmen have a degree of qualification designated by the corresponding categories.

Tasks solved by industrial equipment mechanics and requirements for them

The job responsibilities of a repairman involve performing such functions as installation and dismantling work, maintenance and repair of machine parts, their components and assemblies, and selection of spare parts required for this. Also, in the course of their professional activities, specialists at this level carry out processing and sharpening of necessary parts, and carrying out preventive maintenance.

Based on this list of operations performed in the work process, a list of requirements for candidates for the position of repairman is formed.

• Knowledge of the manufacture and design of the equipment being serviced.
• An understanding of basic kinetics and mechanics is required.
• A specialist must have accuracy, patience and responsibility.
• The employee must have skills in the selection of lubricating fluids, their purpose and characteristic properties.
• A mechanic must have an understanding of the general principles and methods of repairing equipment and its parts and be able to apply this knowledge in practice.

The qualifications of repairmen are confirmed by assigned ranks.

Operations performed by mechanics according to available categories

As the employee's qualifications increase, the complexity and responsibility of the processes performed increases. According to the unified tariff and qualification reference book (ECTS), a repairman has the following job responsibilities.

The list of job responsibilities of a 1st category mechanic includes operations for adjusting threaded connections, preparing parts and mechanisms for repairs, and cleaning them. As well as preparing metalwork tools for technical work: cleaning, sharpening and lubrication.

Worker 1st qualification category must have knowledge of the basics of the operations performed, the names of the tools used, types of lubricating fluids and their purpose.

Repairman 2nd category performs the functions of repair and maintenance of simple mechanisms, components and mechanisms. If it is necessary to carry out work with parts of medium complexity, it is carried out under the supervision of a more qualified employee. Allowed to perform work using electrical and pneumatic equipment.

Requirements for workers at this level include knowledge of the basic principles of prefabricated and disassembled operations of components and assemblies, the purpose and methods of using precision measuring instruments, and the physical properties of materials used during the work.

Workers of the 3rd category perform operations on metalworking of parts, carrying out prefabricated and disassembled work on components and assemblies of medium complexity. As well as repair and testing work with various mechanisms and elements.

Due to the nature of the tasks performed, workers in this category are subject to requirements such as knowledge of the principles of the design and operation of the equipment being repaired. Also technologies for assembly and disassembly operations. The employee must know the physical properties of the materials being processed.

Responsibilities of a 4th category repairman equipment. This implies installation and dismantling work in the units and assemblies of these mechanisms, and commissioning work. A repairman of this qualification must draw up defect sheets for equipment. Professional responsibilities also include the manufacture of instruments for repair and installation work.

In accordance with this functionality, a repairman must know the structure and principle of operation, the main devices for carrying out repair work, and the technology of using precision measuring instruments. The employee must be able to troubleshoot problems during repairs and maintenance. Have knowledge in the field of marking parts and skills in adjusting mechanisms.

Responsibilities of a 5th category repairman repair and maintenance of complex equipment and mechanisms under stressful and dense conditions. Installation and dismantling, as well as commissioning work for complex components and assemblies. Handover of equipment after necessary repair operations. Elimination of premature wear of equipment.

A locksmith of the 5th category must know and be able to, in addition to other basics of plumbing, technology for making adjustments and monitoring the correct installation of equipment. And also have the skills to conduct static and dynamic balancing tests. It is important that the employee can determine the presence of premature wear of equipment elements and eliminate it using reinforcements and the application of protective coatings.

Professional responsibilities repairmen of the 6th and higher categories. At the same time, they apply to complex large-sized and experimental equipment. For example, a repairman of this skill level must be able to work with supercentrifuges, computer-controlled machines, hydraulic and steam-hydraulic presses, and others.

Seventh and eighth qualification category assigned only when working in those workshops that use unique and experimental equipment in their work.

According to the principle described above, as the operations performed become more complex, qualifications are assigned to rolling stock repairmen.
