Garnett Cross Training in the Maintenance of Oil Hydraulics
This course will prepare you to work with hydraulic systems, plan maintenance and perform troubleshooting.
Description
Presented by the late Garnett Cross who was an industry leader in hydraulics.
Garnett provided in-person training and consulting for 47 years - 1974 - 2021. His clients included the major corporations in manufacturing, mining, military, shipping and rail.
The training has helped many organizations resolve expensive downtime and ongoing maintenance costs. In addition to the course material, Garnett will share some of my consulting experiences helping get plants back online and resolve ongoing maintenance costs.
Students from many countries have attended the courses including African states, United States, Emirates, Indonesia, and Europe.
The presentations include animated PowerPoint slides and demonstrations of hydraulic components.
Calculations are provided using metric units.
