The program includes a semester of guided career exploration in the construction industry, plus courses in construction math, construction equipment fundamentals, and mobile equipment maintenance. Students who successfully complete the program are eligible to enter a registered apprenticeship program with the International Union of Operating Engineers (IOUE) Local 49 in Minnesota or IUOE 139 in Wisconsin and receive credits from a community college in their state.
There are numerous examples of mobile hydraulic machines used in agriculture, construction or load-lifting equipment; vibration on the load and the structure of the machine affects productivity and operator comfort and safety.
Company Description: Astec Industries, Inc. designs, engineers, manufactures and markets equipment and components used primarily in road building and related construction activities. The Company operates through two segments: Infrastructure Solutions and Materials Solutions. The Infrastructure Solutions segment consists of approximately 12 sites and designs, engineers, manufactures and markets a complete line of asphalt plants, concrete plants and their related components and ancillary equipment, as well as supplying other heavy equipment. The Materials Solutions segment consists of nine sites and designs and manufactures heavy processing equipment, in addition to servicing and supplying parts for the aggregate, metallic mining, recycling, ports and bulk handling markets. Its products are marketed both domestically and internationally primarily to asphalt producers; highway and heavy equipment contractors; utility contractors; construction, demolition, recycle and crushing contractors, and others.
Actuators are thus present in everything around us, from the access control systems on our doors to the robots doing the heavy lifting at the local warehouse. Even our mobile phones have actuators to create vibrations when they're turned on silent.
Mobile construction equipment: Using rotary actuators within the mobile construction industry can be useful where there is limited rotational energy and more compact solutions are required.
Students in the Diesel Technology program train to be dieselmechanics who repair diesel-powered trucks and heavyequipment. Students study hydraulics, electrical systems, fuelsystems, power trains, air conditioning, brakes and suspension,engine theory, and engine diagnosis, beginning with basicprinciples and proceeding to an advanced level of systemtechnology. Along with these core courses, students takeclasses in welding, machining, computers, physics,communications, and math.
Students in the Heavy Equipment Operation program aretrained to safely and properly operate and maintain a variety ofheavy equipment. They learn to operate equipment includingcrawler-tractors, graders, scrapers, front-end loaders,excavators, backhoes, and dump trucks. Students develop anunderstanding of basic surveying techniques, receive extensivetraining in safety regulations and procedures, and learn how tohandle controls precisely and judge distances accurately.
Students in the program are trained to be recreational powerequipment technicians who repair and maintain a wide varietyof 2-stroke and 4-stroke cycle engines and related equipment.Students work on motorcycles, ATVs, snowmobiles, outboardmotors, and personal watercraft. Units of instruction includemechanical, fuel, and electrical systems.
