MECT 1340 - Mobile Hydraulics Technology
Credit Hours: 3.00
Prerequisites: MECT 1320 or approval of instructor
(formerly MECT 2911)
This course teaches the fundamentals of mobile-hydraulic systems including components, graphic symbols and basic circuit configurations. Students will calculate the area of a hydraulic actuator in square inches, extension and retraction forces in pounds, pressure in pounds per square inch, and speed in inches per min. Students will draw and simulate mobile hydraulic circuits using Automation Studio then connect the actual circuit on a functional hydraulic trainer.
