Ontario College Certificate in Heavy Equipment Techniques (Co-op) Curriculum
Accepting Applications for January 2019
Courses and Descriptions
This course studies electrical fundamentals including magnetism, current, voltage, resistance, series and parallel circuits. Meter usage, test equipment and electrical schematics will be emphasized. Electrical systems on heavy equipment such as batteries and starters will be tested and evaluated.
This Engines I course will cover the theory, and knowledge required to recondition a four stroke diesel engine. Fastener identification, torqueing procedures and use of fine measuring tools will be taught. Students will learn the theory and operation of a four stroke internal combustion diesel engine and its subsystems. Measuring and inspection of components for reuse are some of the major skills developed. In lab groups, students will perform a complete disassembly and reassembly of an internal combustion engine long block. The shop work, which is a critical part of this course, is designed to enhance the students learning of the topics discussed in the theory section of this course.
This course begins with general hydraulic fundamentals and leads into a detailed study of hydraulic systems on heavy mobile equipment. Topics include pumps, cylinders, control valves, reservoirs, actuators, lines and fittings, fluids, hydraulic control circuits for machine implement, drive and steering functions, and troubleshooting of hydraulic systems on machines.
Electronic technology has significantly increased the opportunity for improved customer service and communication skills in the heavy equipment industry. This course reviews product support systems such as machine tracking, security, productivity, maintenance and scheduling. This technology allows for the monitoring of current machine status and provides technicians with real time data for repair and maintenance to reduce machine down time thus providing better customer service. Proper techniques will be employed when composing technical service reports.
This is the first of a two-part course (Powertrains I and Powertrains II) and it covers clutches, standard transmissions, planetary gearing, propeller shafts and U-joints, standard, no spin and limited slip differentials, planetary and non-planetary axles, final drives, air, hydraulic and disc brakes, tires and tire sizes, undercarriages, winches, suspension systems, machine safety, and maintenance procedures. The shop work, which is part of this course, is designed to amplify the students' understanding of the topics discussed in the theory part of the course.
This comprehensive course introduces students to the basics of maintenance and repair of heavy equipment according to OEM operation and maintenance manuals. Safe practices for shop equipment along with the safe use of shop tools are emphasized at all times. The successful student will be able to demonstrate how to safely manoeuver different types heavy equipment. This hands-on course includes the maintenance of machines and machine systems. Reporting and documenting of equipment servicing will be expected during the course.
Students' skills will be developed in all types of gas welding and cutting. Arc welding procedures will be practiced. In addition, students will study basic metallurgy and strength of materials.
All graduates of diploma programs require general education credits. These courses allow you to explore issues of societal concern by looking at the history, theory and contemporary applications of those issues.
Your program has designated some required general education courses. In addition, you have the opportunity to choose from a list of electives each semester.
Many of these courses and some other general education courses are also available through evening classes, by distance education, or on-line. See our Part-Time Studies Calendar for these opportunities.
You may already possess general education equivalencies from other colleges or universities. Please see the General Education Co-ordinators at the Peterborough and Lindsay locations for possible exemptions.
Co-op is an integral part of the learning and mentoring process for the trainees of the Heavy Equipment Techniques program. Students will be required to complete a minimum of 450 hours (15 weeks) of co-op work experience in a related field. This co-op work experience will allow students to apply the skills they have developed in the first semester. This credit must be earned before a diploma can be granted.
This course is a continuance of Electrical Systems I. Students will study more in-depth electrical fundamentals. Electronic devices such as semiconductors and other solid state devices will be emphasized and their applications in alternators, regulators and controls. Oscilloscope usage and proper wiring repair will be studied. Various types of wiring schematics and their interception will be analyzed.
This course is an in-depth study of electronic engine controls including fuel and emission management for both gasoline and diesel engines. The focus will be to evaluate engine computer systems and their components including input and output devices such as sensors, actuators and stepper motors, etc. Other subsystems such as electronic transmission controls and antilock braking systems will be studied. System diagnosis and schematic interruption will be the main emphasis.
Engines II will build on the knowledge the student has gained from the successful completion of Engines I. It will start with a review of engine breathing and pressure differentials that occur during the four stroke combustion cycle. The course will then cover the principals, purpose, functions and fundamentals of low pressure diesel fuel subsystems, mechanical governors, hydraulic fuel injectors and a variety of high pressure fuel systems including: inline port helix, rotary distributor, mechanical unit injector, mechanical electronic unit injectors, hydraulic electronic unit injector, electronic unit pump and high pressure common rail. Partial and full authority high pressure fuel injection systems will also be incorporated into the course. An emphasis will be placed on the diagnosing of both the low and high pressure fuel systems and a variety of engine operation concerns.
This is the second of a two-part course (Hydraulic Systems I and Hydraulic Systems II) which is a detailed study of advanced hydraulic systems used in the heavy equipment industry. The study begins with a review of hydraulic principles and culminates with a comprehensive study of systems containing pressure and temperature compensating systems and load sensing capabilities. Also detailed will be the theory and operation of pneumatic circuits for brakes, schematics and ISO symbols. Students will receive extensive hydrostatic drive systems training and evaluation of operating systems.
This is the concluding part of a two-part course which covers torque converters, clutch packs, powershift, automatic and hydrostatic transmissions. It also covers electronically controlled powershift transmissions, hydraulic propulsion systems and electronically controlled hydrostatic drives, as well as machine safety and maintenance procedures. The shop work, which is part of this course, is designed to amplify students' understanding of the topics discussed in the theory portion of the course.
Course continues from Trade Practices I
