Program Experiences

Practical Application

The heart of Heavy Equipment is the Diesel Engine like this Caterpillar C – 12.

Up To Date Technology

Heavy Equipment Mechanics use of State of the Art Electrical Training Aids will provide a firm foundation for troubleshooting of Advanced electronics.

Current Engine Technology

You will be challenged performing complete rebuild of diesel Engines like those that use the Common Rail fuel system.

Prepare for the Challenge

Heavy Equipment Mechanics require a mastery of many systems; Hydraulics, Engine, Power Train and Electronics. To demand the best compensation you must be prepared for the challenge. Through practicing on machines and use hydraulic trainers you will master this challenge.

Heavy Equipment Machines

Gain practical experience working on machines like this 160M Caterpillar Motor Grader.

Hands-On Performance
There is little that can replace hands-on reinforcement of system principles like testing and making adjustment to real Heavy Equipment.


What better way to master the fundamentals of power train systems than to perform complete rebuild of a motor grader and scraper transmission.
