Hydraulic Shovel Maintenance and Troubleshooting
Event Details
LEVEL II
6 DAY
INSTRUCTOR-LED COURSE
Learn to:
Use complex schematics as a troubleshooting tool
Verify correct functioning of shovel hydraulic circuits
Develop a reliability based approach to system maintenance
Prepare a methodical troubleshooting "battle plan" in advance
In this course, technicians, mechanics, and reliability specialists learn to identify the major hydraulic circuits on a mining shovel. With a careful examination of major pump groups, pressure controls as well as pilot and directional valving, participants learn to verify correct and normal hydraulic shovel functions.
Participants move forward with knowledge of correct functions and settings as well as reliability based maintenance practices for fluid cleanliness, temperature, and leak control to conduct logical fault finding as a team. A method of analysis for determining faults based on "knowing what normal is" will be taught taught along with our Ten Step Troubleshooting Process. Schematic reading and safe work practices are core topics throughout.
This extensive eight-day course is taught with live hydraulic circuit training panels (like the ones shown here), troubleshooting simulation software, on-machine exercises, and through instructor guided, hands-on study of valves. On-screen simulations and Live Schematics bring the systems to life for intensive and rigorous training. We can build and deliver a training program specific to the model of hydraulic shovel you use.
