Your conveyor gives you warning signals weeks before it fails. Most production teams miss them — and pay for it with unexpected downtime, damaged goods and emergency repair costs.
Here are the 7 warning signs every plant engineer should know:
━━━━━━━━━━━━━━━━━━
🔴 WARNING 1 — Belt Drifting or Tracking Off-Centre
━━━━━━━━━━━━━━━━━━
What you see: Belt moves consistently to one side during operation
Root cause: Worn or misaligned idlers, off-centre loading, belt join not square, frame not level
Risk if ignored: Belt edge damage, material spillage, full belt derailment
Fix: Idler realignment, loading point adjustment, belt re-joining
━━━━━━━━━━━━━━━━━━
🔴 WARNING 2 — Unusual Noise from Drive, Gearbox or Rollers
━━━━━━━━━━━━━━━━━━
What you hear: Grinding, squealing, clicking or thumping sounds
Root cause: Worn bearings, dry or failed lubrication, loose coupling, damaged sprocket
Risk if ignored: Bearing seizure, shaft damage, motor burnout
Fix: Bearing replacement, lubrication check — address within 48 hours
━━━━━━━━━━━━━━━━━━
🔴 WARNING 3 — Material Spillage at Transfer or Loading Points
━━━━━━━━━━━━━━━━━━
What you see: Material falling off belt edges or at chute transitions
Root cause: Worn or missing skirting rubber, incorrect belt speed vs feed rate, belt sag
Risk if ignored: Material waste, housekeeping hazard, belt surface damage
Fix: Replace skirting, adjust loading rate, tension belt correctly
━━━━━━━━━━━━━━━━━━
🔴 WARNING 4 — Belt Surface Cracking, Fraying or Edge Damage
━━━━━━━━━━━━━━━━━━
What you see: Belt top cover cracking, edge fibres exposed, chunks missing from surface
Root cause: UV exposure (outdoor conveyors), abrasive material, age, belt tracking off
Risk if ignored: Belt joint failure, sudden belt break during production
Fix: Full belt replacement — do not delay once surface damage is visible
━━━━━━━━━━━━━━━━━━
🔴 WARNING 5 — Drive Motor or Gearbox Overheating
━━━━━━━━━━━━━━━━━━
What you feel: Motor casing too hot to touch (>80°C), smell of burning insulation
Root cause: Overloading beyond rated capacity, VFD fault, lubrication failure, blocked cooling fan
Risk if ignored: Motor winding burnout, gearbox seizure, fire risk in dust environments
Fix: Check load vs rated capacity, check lubrication, inspect VFD parameters
━━━━━━━━━━━━━━━━━━
🔴 WARNING 6 — Conveyor Belt Running Slow or Jerking
━━━━━━━━━━━━━━━━━━
What you see: Inconsistent belt speed, belt lurching or stalling under load
Root cause: Belt slippage on drive pulley (worn lagging), VFD fault, overload condition
Risk if ignored: Product damage, jam events, motor damage
Fix: Re-lag drive pulley, check VFD output, reduce loading
━━━━━━━━━━━━━━━━━━
🔴 WARNING 7 — Vibration in Structure or Frame
━━━━━━━━━━━━━━━━━━
What you feel: Excessive vibration in conveyor frame during operation
Root cause: Loose fasteners, imbalanced pulleys, worn rollers with flat spots
Risk if ignored: Structural fatigue, loose components becoming projectile hazards
Fix: Tighten all fasteners, replace worn rollers, balance pulleys
