ELM 5010 - Hydraulics I
Clock Hours: 30
Delivery Mode
on-ground
Prerequisites: Maintenance Electrician Diploma
Course Description:
This is an advanced technology training course and a comprehensive maintenance training system for industrial hydraulics. The Explorer II Industrial Hydraulics Training System provides the components and hands-on training required to effectively troubleshoot and repair hydraulics systems used in modern industry. The curriculum focuses on the background, applications and maintenance of hydraulics equipment and begins with the fundamentals of hydraulics, which can be used as either an introduction to the technology or as a review of key principles. Additional sections focus on different types of valves, cylinders and hydraulic devices like hydraulic jacks and regenerative circuits.
