TRAINING COURSE:
Mobile Hydraulic Systems
Course Category: Transmission and Distribution
Course description: The purpose of this course is to teach basic operation and maintenance of mobile hydraulic systems used on line trucks. The course presents the basic principles of hydraulic power and explains how these principles are used to produce motion. Inspection and routine maintenance of mobile hydraulic systems are also discussed. At the conclusion of this course, participants should have a basic understanding of how mobile hydraulic systems operate. They should be able to identify components of a mobile hydraulic system and explain how they function. They should also be able to inspect a mobile hydraulic system and perform minor maintenance.
