HEAVY EQUIPMENT TECHNOLOGY– CURRICULUM AND CLASS DESCRIPTIONS

The Heavy Equipment Technology program prepares students to perform maintenance, troubleshooting, and rebuilding of the major components of earth moving equipment.  Instruction is provided in the classroom on theory, inspection, maintenance, troubleshooting, and repair of tracks, wheels, brakes, operating controls, hydraulic systems, electrical circuitry, electronic and mechanical engines, and manual and power shift transmissions. Some equipment operation is included to familiarize students with the equipment they are learning to repair.

The Heavy Equipment Technology program contributes to the green economy by updating the curriculum as needed each year to introduce the latest technology used to meet Environmental Protection Agency (EPA) regulations regarding emissions control systems.  Additional technology covered includes hybrid assist systems, dual-fueled engines, and the current tier level diesel engines that produce post-combustion air that is cleaner than the intake air, which positively affects the carbon footprint.

Graduates of the two-year Associate of Applied Science degree program will have the technical competencies required to be productive in an entry-level heavy equipment technician position. They can expect to find employment with construction companies, heavy equipment sales and service organizations, dealers, state highway maintenance departments, and mining companies.  The Heavy Equipment Technology program is accredited by the Associated Equipment Distributors (AED) Foundation and the Association of Technology, Management, and Applied Engineering (ATMAE).

Due to industry employment requirements, students are required to earn a Class A Commercial Driver License (CDL) before graduation.  The CDL training and licensing require students to:  1) maintain a driving record that is eligible for a Missouri Class A CDL, 2) obtain a complete, current, and valid Medical Examination Report and Certificate for Commercial Driver Fitness Determination, and 3) successfully pass drug screen(s).

It is a graduation requirement of the Heavy Equipment Technology (HET) program for students to earn a grade of “C” or better in all “Core Curriculum” and “Program Requirements” courses; due to state licensing requirements, students must earn a grade of “B” or better in the CDL classes.

Program Mission

The mission of the Heavy Equipment Technology program is to provide students with the opportunity to develop the technical and interpersonal skills necessary to succeed in today’s Heavy Equipment Technology field.

 Program Goals

The goals of the program are to provide the opportunity for students to develop:
