|Nature of the Work||[About this section]||[To Top]|
A wide range of employees is required to keep sophisticated industrial machinery running smoothlyfrom highly skilled industrial machinery mechanics to lower skilled machinery maintenance workers who perform routine tasks. Their work is vital to the success of industrial facilities, not only because an idle machine will delay production, but also because a machine that is not properly repaired and maintained may damage the machine, the final product or injure an operator.
The most basic tasks in this process are performed by machinery maintenance workers. These employees are responsible for cleaning and lubricating machinery, performing basic diagnostic tests, checking performance, and testing damaged machine parts to determine whether major repairs are necessary. In carrying out these tasks, maintenance workers must follow machine specifications and adhere to maintenance schedules. Maintenance workers may perform minor repairs, but major repairs are generally left to machinery mechanics.
Industrial machinery mechanics, also called industrial machinery repairers or maintenance machinists, are highly skilled workers who maintain and repair machinery in a plant or factory. To do this effectively, they must be able to detect minor problems and correct them before they become major problems. Machinery mechanics use their understanding of the equipment, technical manuals, and careful observation to discover the cause. For example, after hearing a vibration from a machine, the mechanic must decide whether it is due to worn belts, weak motor bearings, or some other problem. Computerized diagnostic systems and vibration analysis techniques are aiding in determining the problem, but mechanics still need years of training and experience.
After diagnosing the problem, the industrial machinery mechanic disassembles the equipment to repair or replace the necessary parts. When repairing electronically controlled machinery, mechanics may work closely with electronic repairers or electricians who maintain the machine's electronic parts. (Statements on electrical and electronic installers and repairers, as well as electricians, appear elsewhere.) Increasingly, mechanics need electronic and computer skills in order to repair sophisticated equipment on their own. Once a repair is made, mechanics perform tests to ensure that the machine is running smoothly.
Primary responsibilities of industrial machinery mechanics include repair, preventive maintenance, and installation of new machinery. For example, they adjust and calibrate automated manufacturing equipment, such as industrial robots. As plants retool and invest in new equipment, they increasingly rely on mechanics to properly situate and install the machinery. In many plants, this has traditionally been the job of millwrights, but mechanics are increasingly called upon to carry out this task. (See the statement on millwrights.)
Industrial machinery mechanics and machinery maintenance workers use a variety of tools to perform repairs and preventive maintenance. They may use a screwdriver and wrench to adjust a motor, or a hoist to lift a printing press off the ground. When replacements for broken or defective parts are not readily available, or when a machine must be quickly returned to production, mechanics may sketch a part to be fabricated by the plant's machine shop. Mechanics use catalogs to order replacement parts and often follow blueprints, technical manuals, and engineering specifications to maintain and fix equipment. By keeping complete and up-to-date records, mechanics try to anticipate trouble and service equipment before factory production is interrupted.
|Working Conditions||[About this section]||[To Top]|
In production facilities, these workers are subject to common shop injuries such as cuts, bruises, and strains. They also may work in awkward positions, including on top of ladders or in cramped conditions under large machinery, which exposes them to additional hazards. They often use protective equipment such as hardhats, safety glasses, steel-tipped shoes, hearing protectors, and belts.
Because factories and other facilities cannot afford to have industrial machinery out of service for long periods, mechanics may be called to the plant at night or on weekends for emergency repairs. Overtime is common among industrial machinery mechanics; about 30 percent work over 40 hours a week.
|Training, Other Qualifications,
|[About this section]||[To Top]|
Machinery maintenance workers typically receive short-term on-the-job training in order to perform routine tasks, such as setting up, cleaning, lubricating, and starting machinery. This training may be offered by experienced workers, professional trainers, or product representatives.
Industrial machinery mechanics, on the other hand, often learn their trade through 4-year apprenticeship programs that combine classroom instruction with on-the-job-training. These programs usually are sponsored by a local trade union. Other mechanics start as helpers and learn the skills of the trade informally or by taking courses offered by machinery manufacturers and community colleges.
Mechanics learn from experienced repairers how to operate, disassemble, repair, and assemble machinery. Classroom instruction focuses on subjects such as shop mathematics, blueprint reading, welding, electronics, and computer training.
Employers prefer to hire those who have completed high school or technical school, and have taken courses in mechanical drawing, mathematics, blueprint reading, computers, and electronics. Mechanical aptitude and manual dexterity are important characteristics for workers in this trade. Good reading comprehension is also necessary to understand the technical manuals of a wide range of machines. And, in general, good physical conditioning and agility are necessary because repairers sometimes have to lift heavy objects or climb to reach equipment.
Opportunities for advancement vary by specialty. Machinery maintenance workers may gain additional skills to make more complex repairs to machinery or work as supervisors. Industrial machinery mechanics also may advance either by working with more complicated equipment or by becoming supervisors. The most highly skilled repairers can be promoted to master mechanic or can become millwrights.
|Employment||[About this section]||[To Top]|
Industrial machinery mechanics and maintenance workers held about 306,000 jobs in 2004. Of these, 220,000 were held by the more highly skilled industrial machinery mechanics, while machinery maintenance workers accounted for 86,000 jobs. Two out of three workers were employed in the manufacturing sector, in industries such as food processing, textile mills, chemicals, fabricated metal products, motor vehicles, and primary metals. Others worked for government agencies, public utilities, mining companies, and other establishments in which industrial machinery is used.
|Job Outlook||[About this section]||[To Top]|
Employment of industrial machinery mechanics and maintenance workers is projected to grow more slowly than the average for all occupations through 2014. Nevertheless, applicants with broad skills in machine repair and maintenance should have favorable job prospects. Many mechanics are expected to retire in coming years, and employers have reported difficulty in recruiting young workers with the necessary skills to be industrial machinery mechanics. Most job openings will stem from the need to replace workers who transfer to other occupations or who retire or leave the labor force for other reasons.
As more firms introduce automated production equipment, these workers will be needed to ensure that these machines are properly maintained and consistently in operation. However, many new machines are capable of self-diagnosis, increasing their reliability and somewhat reducing the need for repairers.
Industrial machinery mechanics and maintenance workers are not usually affected by changes in production. During slack periods, when some plant workers are laid off, mechanics often are retained to do major overhaul jobs and to keep expensive machinery in working order. Although these workers may face layoffs or a reduced workweek when economic conditions are particularly severe, they usually are less affected than other workers because machines have to be maintained regardless of production level.
