Tipper trucks fail in ways other trucks don’t. Standard road trucks don’t have hydraulic bodies that raise 5,000+ kg of steel above the chassis; don’t have tailgates whose latch failure dumps loads on the road; don’t have hinges under continuous stress from raising and lowering daily. The inspection below covers what experienced tipper operators check every shift — before failures become breakdowns, fines, or injuries.
Walk-around external inspection
1. Tyres
- Visual check all wheels for cuts, bulges, embedded objects (nails are common on construction sites)
- Tread depth — legal minimums vary; aim for at least 4mm on steers, 2mm on drives
- Pressure — visual check for obvious low pressure; gauge check at least weekly on all positions
- Sidewall damage — sidewall cuts are immediate replacement
2. Wheels and hubs
- Lug nut markers — look for paint stripe shift indicating loose nuts
- Hub condition — leaks suggest seal failure
- Wheel rim — cracks, especially after curb hits
3. Body external
- Sides and front wall — dents, bulges (indicates internal damage), corrosion
- Tailgate — latches both sides, hinges intact, sealing closed when latched
- Body hinges (pivot points) — visible wear, cracks at welds, lubrication
- Body floor (inside) — wear-plate condition, holes
4. Cab and signals
- Headlights, indicators, brake lights — all working
- Reverse alarm — required by law in most jurisdictions
- Mirrors — clean, undamaged, correctly adjusted
- Windscreen — chips and cracks (fines and visibility issues)
- Reflectors — required on commercial vehicles
Hydraulic system inspection
5. Hydraulic fluid
- Reservoir level — visible in tank sight glass or by dipstick; top up to within marks
- Fluid colour — clean amber/red is normal; black or milky indicates contamination requiring service
- Visible leaks — under truck, around cylinders, at hose fittings
6. Hydraulic hoses
- Abrasion damage — chafe marks where hoses contact frame or other components
- Bulges — internal damage; replace immediately
- End fittings — leaks at the crimp indicate hose failure imminent
- Tight bends — hoses that have been kinked are damaged even if they don’t leak yet
7. PTO and pump
- PTO engagement — engages cleanly without grinding (with transmission engaged correctly)
- Pump noise — squealing or unusual noises suggest failure approaching
- Vibration during operation — increased vibration is a warning sign
8. Test lift (empty body)
- Smooth rise through full range — no shudders, hesitations, or noises
- Smooth descent under control — descent should be steady, not free-falling at any point
- Full retraction — body sits fully on chassis frame; gaps indicate problem
Brake system
9. Air system (for air-braked tippers)
- Pressure build to operating range (typically 110-130 PSI)
- Low-air warning at 60 PSI — buzzer and warning light
- Air leak test — engine off, application held, pressure should drop less than 3 PSI per minute
- Parking brake test — apply, attempt to drive forward gently in low gear; truck should not move
10. Brake linings and drums (monthly minimum)
Visual inspection of brake chambers, push-rod stroke, drum condition. Beyond visual, full inspection requires lift; arrange with maintenance shop at regular intervals.
Steering and suspension
11. Steering
- Steering wheel free play — within manufacturer spec (typically 5-10 degrees)
- Power steering fluid — level, no leaks
- Tie-rod ends — visible boots intact, no slop
12. Suspension
- Air bags (if fitted) — inflated, no visible damage
- Leaf springs — no broken or cracked leaves
- Shock absorbers — no leaks, mounting bolts tight
- U-bolts — tight, no missing nuts
Cab interior
13. Controls and gauges
- All gauges functional — temperature, pressure, fuel
- Warning lights — verify they illuminate at startup, extinguish after start
- Switches and controls — all working including tipper hoist control
- Wipers and washers — working at all speeds
- Horn — functional
14. Documentation
- Operator’s licence/permits
- Vehicle registration current
- Insurance certificate
- Inspection certificate
- Logbook (if required)
Common findings — when to red-tag the truck
The following defects mean the truck doesn’t roll until repaired:
- Any hydraulic leak more than weeping
- Cracked body hinges or stress points
- Failing tailgate latch on either side
- Brake system air leak above spec
- Steering free play above manufacturer limit
- Tyre cuts to cord, sidewall damage, or below legal tread
- Cracked wheel rim
- Failing brake light or reverse alarm
The 15-minute pre-shift habit
Daily inspection takes 15-20 minutes done properly. This investment:
- Catches developing problems before catastrophic failure
- Establishes documentation if accidents happen later
- Meets regulatory requirements in most jurisdictions
- Saves substantial money over reactive maintenance
Drivers who skip pre-shift inspections are the ones who break down on the job.
A defect found early is easier to manage
Daily walk-around, hydraulic system check, brake test, controls verification. Red-tag for any safety-critical defect. Document findings. Tipper-specific failures (hydraulics, hinges, tailgates) catch operators by surprise when daily inspection is skipped. Follow your operator’s specific procedures and consult an ASE-certified or equivalent technician for anything beyond visual inspection.
The handover is part of the inspection
When more than one driver uses the truck, the incoming driver needs more than a signed sheet. Pass on recent repairs, intermittent warnings, body or tailgate behaviour and any site condition that affected the previous shift. A defect that appears “normal” to one driver can be new and important to the next.
Keep the handover factual. State what happened, when it happened and whether the truck was assessed or repaired. Avoid vague comments such as “keep an eye on it” when the item requires a clear decision.
