Overview

• The Hydraulics I Training System gives students a solid foundation in, and hands-on experience with hydraulic components and circuits; the transmission of force through liquids; conversion of force to pressure; the control of power; and systematic methods of troubleshooting and testing hydraulic systems.

  The Hydraulics II Training System, an add-on to the Hydraulics I Training System, introduces students to electrical concepts and electrically controlled hydraulic systems. Through hands-on experimentation, students gain familiarity with functional and industrial electrically controlled hydraulic systems while learning systematic methods of troubleshooting and testing electrically controlled hydraulic systems.
