What is on a heavy equipment inspection checklist?
Use one sheet per machine per shift. Write the machine number, hour meter reading, operator and date at the top, tick each item, and write any defect in the notes column.
1. Walk-around (engine off, machine parked on level ground, bucket or blade on the ground)
| Check | What good looks like | OK | Defect |
|---|---|---|---|
| Ground under the machine | No fresh oil, coolant, fuel or hydraulic fluid | ☐ | ☐ |
| Tracks or tyres | Track tension even, no missing pads or pins; tyres inflated, no cuts or bulges, wheel nuts present | ☐ | ☐ |
| Undercarriage | Rollers, idlers and sprockets not seized or leaking | ☐ | ☐ |
| Hydraulic hoses and cylinders | No leaks, chafing, cracks or bulges; rods not scored | ☐ | ☐ |
| Boom, stick, arms and frame | No cracks, bent sections or broken welds | ☐ | ☐ |
| Pins, bushings and greasing points | Pins and keepers in place; greased to the maker's schedule | ☐ | ☐ |
| Bucket, blade, forks or attachment | Teeth and cutting edges secure; quick coupler locked with the safety pin fitted | ☐ | ☐ |
| Guards, steps and handrails | In place, secure, clear of mud and ice | ☐ | ☐ |
| Lights, mirrors and cameras | Clean, unbroken, correctly aimed | ☐ | ☐ |
| Fire extinguisher | Present, charged, inspection tag current | ☐ | ☐ |
2. Fluid levels (engine cold)
| Check | What good looks like | OK | Defect |
|---|---|---|---|
| Engine oil | Between the dipstick marks, not milky | ☐ | ☐ |
| Coolant | At the reservoir mark; never open a hot radiator cap | ☐ | ☐ |
| Hydraulic oil | At the sight glass mark with the machine in the maker's check position | ☐ | ☐ |
| Fuel and DEF | Enough for the shift; caps secure | ☐ | ☐ |
| Air filter indicator | Not in the red zone | ☐ | ☐ |
| Belts | Tension correct, no cracks or fraying | ☐ | ☐ |
3. Cab and function test (engine running, area clear)
| Check | What good looks like | OK | Defect |
|---|---|---|---|
| Access and seat belt | Three points of contact on the way in; belt latches and retracts | ☐ | ☐ |
| ROPS / FOPS and glass | No damage or unapproved modifications; windows clean and uncracked | ☐ | ☐ |
| Gauges and warning lights | All warnings clear after start-up | ☐ | ☐ |
| Horn and reverse alarm | Both clearly audible | ☐ | ☐ |
| Service and park brakes | Hold the machine; park brake holds on a grade | ☐ | ☐ |
| Steering | Responds smoothly in both directions | ☐ | ☐ |
| Hydraulic controls | Every function moves smoothly, no drift, controls return to neutral | ☐ | ☐ |
| Lockout lever / safety controls | Hydraulic lockout disables the controls | ☐ | ☐ |
| Wipers, lights and beacon | All working | ☐ | ☐ |
Operator signature: · Supervisor sign-off for defects: · Machine safe to operate: ☐ Yes ☐ No, tagged out
How often should heavy equipment be inspected?
Heavy equipment should be inspected by the operator before every shift, then at the maker's service intervals counted in engine hours (commonly every 250, 500 and 1,000 hours). Many fleets add a weekly check of greasing, undercarriage wear and attachments. Machines working in dust, mud, demolition or mining usually need shorter intervals than the standard schedule.
What should an operator do when a check fails?
Split defects into two groups. Anything that affects stopping, steering, visibility, rollover or falling-object protection, warning devices or hydraulic control means the machine does not run: remove the key, hang a danger or out-of-service tag, tell the supervisor and record the defect. Minor items such as a cracked step tread or a missing decal are recorded with an owner and a date and fixed at the next service. The machine goes back into use only when someone competent has signed the repair off.
Pre-shift inspection vs periodic inspection
The pre-shift inspection is the operator's walk-around and function test before use. A periodic inspection is a deeper check by a mechanic or competent person at set hours or months: structural cracks, wear measurements, oil analysis, brake testing and the items the maker lists for that service. Cranes and lifting equipment also have their own annual inspection requirements. The daily checklist catches what changed since yesterday; the periodic inspection catches slow wear.
Running inspections across a fleet
One machine with one operator can get by on a paper book in the cab. A fleet of thirty machines across three sites cannot, because the defects written on paper only reach the workshop when someone collects the books. The pattern that works is the same as operator care in total productive maintenance: the operator does the pre-shift check, each defect becomes an action with an owner and a due date, and the supervisor reviews open machine defects in the daily huddle. Defects that repeat on the same model are a reliability problem for the maintenance plan, not an operator problem.
Step by step
- Park and isolate. Park on level ground, lower the bucket or blade, apply the park brake and switch the engine off before walking around.
- Walk around the machine. Check the ground for leaks, then tracks or tyres, hoses, cylinders, boom, pins, attachment, guards, lights and fire extinguisher.
- Check fluids. With the engine cold, check engine oil, coolant, hydraulic oil, fuel, DEF, belts and the air filter indicator.
- Test from the cab. Belt on, start the engine, confirm warnings clear, then test horn, reverse alarm, brakes, steering, hydraulic functions and the lockout lever.
- Record and sign. Write the hour meter reading, tick each item and sign the checklist.
- Tag out or report defects. Tag out the machine for any safety-critical defect and tell the supervisor; record minor defects with an owner and a due date.
A worked example
A civil contractor running about thirty excavators, loaders and rollers across three road projects kept paper pre-start books in each cab. Defects reached the workshop only when the books came back on Fridays. After moving the pre-start to a phone checklist, each defect reached the plant coordinator within minutes. In the first month the open defect list showed the same hydraulic hose chafing on one excavator model at the boom clamp; the fitters changed the clamp position on all five machines and the repeat leaks stopped.
