Course Description:

This training course deals with an important issue related to use of mobile equipment that is the hydraulics used in such equipment. The course focuses on clarifying the types of hydraulic circuits, their components, their components, their maintenance requirements and producers, and their troubleshooting.

Course Goal:

To enhance the participants’ knowledge, related to hydraulic circuits used on mobile equipment either for earthmoving and cutting, or for load lifting, or for carrying out other jobs. This knowledge includes; types of hydraulic circuits, components, oils used, oil filtration, pumps, control valves, and maintenance and troubleshooting of these circuits.

Course Objectives:

By the end of this course, the participant will be familiar with:

1. Types of hydraulic circuits (open, closed)
