01Common Occupational Skills: Safety, Tools, Communication and Documentation
Hazard assessment comes first: identify the task, the energy sources and the people affected, then control risk in the correct order - eliminate, substitute, engineer, administrate - and only then rely on PPE, which is the last line of defence, never the first. The lockout/tagout sequence is: notify, shut down, isolate, apply locks and tags, release stored energy (springs, capacitors, elevated loads, trapped hydraulic pressure, gravity), then verify.
312 words, about 2 min02Rigging, Hoisting and Lifting
Every lift starts with weight and centre of gravity. An off-centre CG makes legs share load unequally even when the sling looks symmetrical.
323 words, about 2 min03Mechanical Power Transmission Systems
For belts, chains and gears the speed ratio is the ratio of driven size to driver size: rpm out = rpm in × (driver / driven). For gears use tooth counts or pitch diameters; for V-belts and chain use pitch diameter, not outside diameter.
315 words, about 2 min04Bearings, Seals, Lubrication and Shafting
Rolling element bearings carry load through balls or rollers; plain bearings carry it on a fluid film and need a steady oil supply. Fit selection follows one rule: the ring that rotates relative to the load direction takes an interference fit, the stationary ring a lighter one.
318 words, about 2 min05Pumps, Compressors and Fluid Power Systems
Centrifugal pumps deliver flow that falls as head rises, and each has a best efficiency point worth running near. Positive displacement pumps move a fixed volume per revolution and must never be dead-headed - they need a relief path.
300 words, about 2 min06Conveyors and Material Handling Equipment
A belt conveyor is a study in tracking and tension. The head pulley drives, the tail pulley returns, and the take-up maintains tension as the belt stretches.
306 words, about 2 min07Preventive and Predictive Maintenance and Troubleshooting
Preventive maintenance is calendar or running-hour based - lubrication, filter changes, inspections, belt checks. Predictive (condition-based) maintenance acts on measured condition: vibration, thermography, oil analysis, ultrasound and performance trending.
305 words, about 2 min08Installation, Alignment and Commissioning
A machine is only as good as what it sits on. Check foundation condition, grout contact, baseplate flatness and bolt torque.
