Industrial Machinery Mechanics and Maintenance Workers
Industrial machinery mechanics and maintenance workers maintain and repair factory equipment and other industrial machinery, such as conveying systems, production machinery, and packaging equipment.††
Industrial machinery mechanics typically do the following:
- Read technical manuals to understand equipment and controls
- Disassemble machinery and equipment when there is a problem
- Repair or replace broken or malfunctioning components
- Perform tests to make sure that the machine is running smoothly
- Adjust and calibrate equipment and machinery
Machinery maintenance workers typically do the following:
- Detect minor problems by performing basic diagnostic tests
- Clean and lubricate equipment or machinery
- Check the performance of machinery
- Test damaged machine parts to determine whether major repairs are needed
- Adjust equipment and reset or calibrate sensors and controls
Industrial machinery mechanics and machinery maintenance workers maintain and repair complex machines, such as an automobile assembly lineís conveyor belts, robotic welding arms, and hydraulic lifts.
The following are the two types of industrial machinery mechanics and machinery maintenance workers:
Industrial machinery mechanics, also called industrial machinery repairers or maintenance machinists, keep machines in good working order. To do this, they must be able to detect and correct errors before they become larger problems.
Machinery mechanics use technical manuals, their understanding of industrial equipment, and careful observation to discover the cause of a problem. For example, after hearing a vibration from a machine, a mechanic must decide whether it is due to worn belts, weak motor bearings, or some other problem. Mechanics often need years of training and experience to diagnose all problems fully. They also use computerized diagnostic systems and vibration analysis techniques to help figure out the source of problems.
After diagnosing a problem, the industrial machinery mechanic may take the equipment apart to repair or replace the necessary parts. Increasingly, mechanics are expected to have the electrical, electronics, and computer programming skills to repair sophisticated equipment on their own. Once a repair is made, mechanics test a machine to make sure that it is running smoothly. Industrial machinery mechanics might also do preventive maintenance.
In addition to handtools, mechanics commonly use lathes, grinders, or drill presses. Many are also required to weld.
Machinery maintenance workers do basic maintenance and repairs on machines. They 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.
Maintenance workers must follow machine specifications and adhere to maintenance schedules. They perform minor repairs, generally leaving major repairs to machinery mechanics.
All maintenance workers use a variety of tools to do repairs and preventive maintenance. For example, they may use a screwdriver or socket wrenches to adjust a motorís alignment. They may use a hoist to lift a heavy printing press off the ground.
Janitors and Building Cleaners
Janitors and building cleaners keep many types of buildings clean, orderly, and in good condition.
Janitors and building cleaners typically do the following:
- Gather and empty trash and trash bins
- Clean building floors by sweeping, mopping, or vacuuming them
- Clean bathrooms and stock them with soap, toilet paper, and other supplies
- Keep buildings secure by locking doors
- Clean spills and other hazards using sponges and squeegees
- Wash windows, walls, and glass
- Order cleaning supplies
- Make minor repairs to the building, such as changing light bulbs
- Notify managers when the building needs major repairs
Janitors and building cleaning workers keep office buildings, schools, hospitals, retail stores, hotels, and other places clean, sanitary, and in good condition. Some do only cleaning, while others have a wide range of duties.
In addition to keeping the inside of buildings clean and orderly, some janitors and building cleaners work outdoors, mowing lawns, sweeping walkways, or shoveling snow. Some janitors also monitor the heating and cooling system, ensuring that it functions properly.
Janitors and building cleaners use many tools and equipment. Simple cleaning tools may include mops, brooms, rakes, and shovels. Other tools may include snowblowers and floor buffers.
Some janitors may be responsible for repairing small problems with electricity or plumbing, such as leaky faucets.
