Whatever your hydraulic applications, you can increase your knowledge of the fundamentals, improve your maintenance programs and become an excellent troubleshooter of problems in this area by attending this information packed course. Cutaways of all major components are brought to the sessions to visually demonstrate the components construction and operation. Developing an understanding of “How” it works leads to an understanding of how and why it fails. Multimedia views of the equipment are given to give you as realistic a view of hydraulic systems as possible.

This hydraulics five-day is highly practical, comprehensive and interactive course. You will have an opportunity to discuss Hydraulic Systems construction, design-applications, and maintenance and management issues and be provided with the most up-to-date information and Best Practice in dealing with the subject. Towards the end of the course, you will have developed the skills and ability to recognize and solve hydraulic problems in a structured and confident manner. 

Upon successful completion of this course, the delegates will be able to:

ü  Identify hydraulic systems components

ü  Describe essential hydraulic terms and understand their key applications

ü  Recognize the impact hydraulic fluids have on components

ü  Describe the correct operation, control sequences and procedures for the safe operation of various simple hydraulic systems

ü  Initiate an effective inspection and maintenance program

ü  Minimize forced outages and prevent series damage to hydraulic equipment

ü  Explain the latest technologies available for electro hydraulic systems

This course is intended for plant engineers, mechanical engineers, design engineers, consulting engineers, operation maintenance, inspection and repair managers, supervisors, plant operations and maintenance personnel, process and mechanical technicians.
