Skills typically required of a maintenance technician involve rigging and lifting heavy equipment, using precision measuring equipment to determine equipment condition, identification and choosing the correct valves, maintaining valves, and the alignment of rotating equipment.  HPC thinks that a Maintenance technician should be able to perform work on these topics to the highest of standards.  Highly skilled technicians, one these subjects specifically, can greatly affect the plant maintenance budget.  It is the intent of this course to enhance these proficiencies.  In each subject area we will review the basic tools used to accomplish the task at hand, we will compare different tools to make sure the best is chosen, we will review acceptable procedures for accomplishing the tasks, make careful notes of where there may be safety risks involved (as well as how to enhance safety), and finally we want to have the skills to evaluate the results.

HPC instructs this course with experienced “mechanics” (often 30+ year’s experience) that have the instructional skills as well.  Much of the course is lecture, but it includes efficient use of lab equipment in HPC facilities so that important tasks are demonstrated and practiced (as needed).  Case studies (examples of lessons learned) are included as well.

Seminar Objectives:
At the completion of this Seminar the participant will be able to:

  1. Identify and describe those lifting devices and/or fixtures commonly used in an industrial facility.
  2. Correctly choose the lifting equipment required for the safe and efficient lift of an assigned job task that involves a lifting procedure.
  3. Visually inspect lifting devices used in the normal daily routine as they pertain to maintenance activities.
  4. Select and use the proper precision measuring instruments for the assigned task.
  5. Accurately measure equipment parts to determine their continued usefulness or warranted replacement.
  6. Accurately set up, check and record the total indictor run out on a rotating element or shaft assembly.
  7. Make valued judgments about equipment condition based on mechanical operating clearances.
  8. Take and record mechanical sizes and conditions as they pertain to the manufacture of replacement parts.
  9. Properly care for and store precision measuring instruments thus ensuring their readiness for and ability to take the next set of accurate readings.
  10. Describe how to select and properly use ladders and scaffolding.
  11. Explain the types and purposes of lubricants.
  12. Identify the various types of bearings found in an industrial application.
  13. Describe the various installation and disassembly of bearings.
  14. Describe the fundamentals of vibration and its effects on rotating equipment.
