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:
Machinery maintenance workers typically do the following:
Industrial machinery mechanics and machinery maintenance workers maintain and repair complex machines, such as an automobile assembly line's 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 motor's alignment. They may use a hoist to lift a heavy printing press off the ground.
Automotive service technicians and mechanics, often called service technicians or service techs, inspect, maintain, and repair cars and light trucks.
Automotive service technicians and mechanics typically do the following:
Service technicians work on traditional mechanical components, such as engines, transmissions, belts, and hoses. However, they must also be familiar with a growing number of electronic systems. Braking, transmission, and steering systems, for example, are controlled primarily by computers and electronic components.
Other integrated electronic systems, such as accident-avoidance sensors, are becoming common as well. In addition, a growing number of technicians are required to work on vehicles that run on alternative fuels, such as ethanol and electricity.
Service technicians use many different tools, including computerized diagnostic tools and power tools such as pneumatic wrenches, lathes, welding torches, and jacks and hoists. These tools usually are owned by their employers.
Service technicians also use many common handtools, such as pliers, wrenches, and screwdrivers, which generally are their own. In fact, experienced workers often have thousands of dollars invested in their personal tool collection.
Service technicians sometimes specialize in a particular type of repair that may be subject to specific regulations or procedures. For instance, those focused on air-conditioning system repairs must follow federal and state regulations governing the handling, recycling, and disposal of refrigerants.
In some shops, technicians may specialize. The following are types of service technicians:
Automotive air-conditioning repairers install and repair air conditioners and service parts, such as compressors, condensers, and controls. They are trained in government regulations related to their work.
Brake repairers adjust brakes, replace brake linings and pads, and make other repairs on brake systems. Some technicians specialize in both brake and front-end work.
Front-end mechanics align and balance wheels and repair steering mechanisms and suspension systems. They frequently use special alignment equipment and wheel-balancing machines.
Transmission technicians and rebuilders work on gear trains, couplings, hydraulic pumps, and other parts of transmissions. Extensive knowledge of computer controls, the ability to diagnose electrical and hydraulic problems, and other specialized skills are needed to work on these complex components.
Tune-up technicians adjust ignition timing and valves and adjust or replace spark plugs and other parts to ensure efficient engine performance. They often use electronic testing equipment to isolate and adjust malfunctions in fuel, ignition, and emissions control systems.

Heavy vehicle and mobile equipment service technicians inspect, maintain, and repair vehicles and machinery used in construction, farming, rail transportation, and other industries.
Heavy vehicle and mobile equipment service technicians typically do the following:
Heavy vehicles and mobile equipment are critical to many industrial activities, including construction and railroad transportation. Various types of equipment, such as farm machinery, cranes, and bulldozers, are used to move materials, till land, lift beams, and dig earth to pave the way for development and construction.
Heavy vehicle and mobile equipment service technicians repair and maintain engines, hydraulic systems, transmissions, and electrical systems of agricultural, industrial, construction, and rail equipment. They ensure the performance and safety of fuel lines, brakes, transmissions, and other systems.
With many types of equipment and mechanical and electrical systems, service technicians use diagnostic computers to identify problems and make adjustments or repairs. Although the use of computerized testing equipment, such as tachometers and dynamometers, is common, technicians also use many different power and machine tools, including pneumatic wrenches, lathes, and welding equipment.
Service technicians also use many different handtools, such as screwdrivers, pliers, and wrenches, to work on small parts and in hard-to-reach areas. They generally purchase these tools over the course of their careers, often investing thousands of dollars in their collections.
After locating malfunctions, service technicians repair, replace, and recalibrate components such as hydraulic pumps or spark plugs. This may involve disassembling and reassembling major equipment or making adjustments through an onboard computer program.
The following are types of heavy vehicle and mobile equipment service technicians:
Farm equipment mechanics service and repair farm equipment, such as tractors and harvesters. They also work on smaller consumer-grade lawn and garden tractors. Most mechanics work for dealer repair shops, where farmers increasingly send their equipment for maintenance.
Mobile heavy equipment mechanics repair and maintain construction and surface mining equipment, such as bulldozers, cranes, graders, and excavators. Many work for equipment wholesale and distribution shops and large construction and mining companies. Those working for the federal government may work on tanks and other military equipment.
Rail car repairers specialize in servicing railroad locomotives, subway cars, and other rolling stock. They usually work for railroad, public and private transit companies, and rail car manufacturers.
