The Tru-Trac SystemFive zones · One engineering standard

Control it like one.

Conveyor failures rarely stay in one place. Mistracking, carryback, spillage and belt damage often begin upstream of the visible problem. Tru-Trac identifies the originating zone and applies the correct engineered control — fixing the cause, not the symptom.

Tru-Trac conveyor render — full bulk-handling installation showing the five zones of control end-to-end.

02 / The five zones

Explore the five conveyor control zones.

Select a zone to see where failures start, what they affect, and which Tru-Trac families control it. Each zone opens to root causes and an inspection checklist.

01LOAD & TRANSFER

REF · TT-ZOC-02 · ZONE MAP

ZONE 01

Load & Transfer

Where many conveyor failures begin.

Off-centre loading, unstable impact and uncontrolled material flow create instability at the start of the belt. Poor containment here becomes belt damage, mistracking and spillage downstream.

Common failures

  • Off-centre loading
  • Unstable material impact
  • Belt sag at the load point
  • Spillage at transfer
  • Mistracking after loading
  • Off-centre discharge from the upstream chute or feeder
  • Worn chute liners deflecting the stream
  • Excess fall height
  • Inadequate impact support or skirting geometry
  • Material not settled before the skirt-end
  • Material delivered on the belt centreline
  • No spillage at the skirt-end
  • Skirting sealed without belt-cover wear
  • Impact bed/rollers undamaged
  • Load-zone idlers clean and free-running
  • Chute liners intact

03 / The failure loop — and how to break it

A failure rarely stays where it starts. Left uncontrolled, one zone drives the next — and the fault returns as repeat downtime, wear and cost.

Operational Impact

  • Early wear and damage
  • Higher maintenance costs
  • Increased safety risk

Tru-Trac Solution

Correct loading alignment and control the upstream cause to keep the belt centred for the full run.

Assess the load zone

When controlled

Broken

Engineered control at the originating zone stops the cascade.

Break it at the source — reactive vs controlled

  • Belt mistracks

    Reactive — Adjust the tracker; it drifts again within a week.

    Controlled — Diagnose the originating zone and correct the upstream cause.

  • Carryback fouls the return

    Reactive — Replace cleaner blades; fouling returns within a month.

    Controlled — Match cleaning specification to material and duty.

  • Belt scale drifts

    Reactive — Recalibrate repeatedly; accuracy keeps moving.

    Controlled — Inspect weigh-zone geometry before calibrating.

  • Belt edges damage

    Reactive — Repair the edge; damage returns downstream.

    Controlled — Find the contact source and correct tracking or structure.

Break the failure loop. Control the zones. Protect the system.

Tru-Trac engineers find the originating zone, apply the correct control, and replace reactive maintenance with planned conveyor performance.

  • Reduce downtime

    Prevent unplanned stops.

  • Lower maintenance cost

    Fix the cause, not the symptom.

  • Improve safety

    Reduce risk and exposure.

  • Protect performance

    Keep your conveyor running.

Start where the failure repeats

that gives you the most trouble.

Send us the belt that keeps failing. We assess the conveyor as a system, identify the originating zone, and recommend the engineered response — not just the last component that broke.
