Industrial Maintenance

Power Transmission

• Bearings: Types, Installation, Failure Modes

  How rolling-element and plain bearings carry load, how to mount and remove them without damaging them, and how to read a failed bearing for the cause.

• Shaft Alignment

  Bringing two shafts into true angular and offset alignment with dial indicators or lasers, and why soft foot ruins the job before you start.

• Belt and Chain Drives

  Selecting, tensioning and aligning belt and chain drives, and the wear patterns that tell you which of those three you got wrong.

• Gearboxes

  How industrial gearboxes transmit and reduce power, what their oil and their noise tell you, and how to open one up without losing the shim pack.

• Couplings

  What each coupling type forgives and what it does not, and why a flexible coupling is never a substitute for alignment.

• Lubrication Fundamentals

  Choosing the right lubricant, applying the right amount at the right interval, and the fact that most bearing failures start as lubrication failures.

• Rigging for Machinery Installation

  Slings, hitches, load angles and center of gravity for lifting and setting machinery, the millwright's defining skill alongside alignment.

Fluid Power

• Hydraulics Fundamentals

  Pressure, flow and the relationship between them, taught through the pumps, cylinders and fluid that move real machinery.

• Hydraulic Components and Circuits

  Pumps, valves, actuators and accumulators, and how to read a hydraulic schematic as a circuit rather than a picture.

• Pneumatics

  Compressed air as a power source: compressors, air preparation, cylinders and valves, and why water in the line is the recurring enemy.

• Hydraulic Troubleshooting

  Working from symptom to cause in a hydraulic system using pressure and flow readings instead of swapping parts.

Rotating Equipment

• Pumps, Mechanical Seals and Packing

  Centrifugal and positive-displacement pumps, mechanical seals and packing: how they work, why they leak, and how to rebuild one properly.

• Industrial Electrical for Mechanics

  The electrical knowledge a mechanic needs to work safely around plant equipment, verify a circuit is dead, and hand off cleanly to an electrician.

• Motor Control Circuits

  Reading and troubleshooting motor starters, control transformers, and the ladder logic behind start/stop stations and interlocks.

• PLC Fundamentals

  What a PLC does on each scan, how its inputs and outputs map to field devices, and how to troubleshoot with the program rather than around it.

• Sensors and Instrumentation

  Proximity, photoelectric, pressure, level and temperature devices: how they signal, how they fail, and how to verify one is telling the truth.

• VFDs in Maintenance

  What a variable frequency drive does to a motor, what its fault codes are telling you, and the cooling and bearing-current problems drives introduce.

• Preventive Maintenance

  Time- and usage-based maintenance: building PM routes and task lists that prevent failure without over-maintaining the equipment.

• Predictive Maintenance: Vibration, Thermal, Oil

  Vibration, thermography and oil analysis as condition indicators, and how to act on a trend before it becomes a breakdown.

• Root Cause Failure Analysis

  Structured failure analysis that gets past the broken part to the reason it broke, so the fix holds.

• The CMRP Certification

  What the CMRP covers, how the exam is structured, and how the five pillars of the SMRP Body of Knowledge map onto plant work.

• The CMRT Certification

  What the CMRT covers, its four domains, what it costs and how it differs from the CMRP.

• Vibration Analyst Certification and ISO 18436

  How vibration analyst certification is structured under ISO 18436, what the four categories mean, and why the standard is not itself a certificate.

• MTBF, MTTR and Maintenance Metrics

  What MTBF, MTTR, availability and PM compliance each measure, what each one hides, and how they drive maintenance decisions.

• The Millwright Apprenticeship

  How the millwright apprenticeship works: about four years of paid on-the-job training and classroom instruction, who sponsors it, and how to get in.

• Maintenance Career Paths: Plant, Field, Planning

  Where maintenance work leads: plant technician, travelling field service, maintenance planning and reliability engineering.

Energy Control

• Lockout/Tagout: Controlling Hazardous Energy

  The rule that governs every maintenance job on powered equipment: who may lock out, what counts as an energy source, and the six steps of applying controls.

• LOTO Procedures and the Annual Periodic Inspection

  Writing machine-specific energy control procedures and running the annual inspection OSHA requires of every one of them.

Machine Hazards

• Machine Guarding

  The guards that stand between a worker and a moving machine part, and the maintenance rule that a guard removed for service goes back on before the machine runs.

• Confined Space Entry for Maintenance

  Recognising a permit-required confined space, the entrant, attendant and entry supervisor roles, and the testing and rescue rules before anyone goes in.
