Meeting the Demands of South African Mining Operations

Coal transport is one of the most punishing logistics tasks in South Africa. Operating 26-ton truck-tractors with dual side-tipper trailers (interlink combinations) at gross combination masses (GCM) exceeding 56 tons puts intense stress on air brake systems.

Mining houses and coal terminal operators (such as those in Mpumalanga and the Richards Bay export corridor) enforce strict safety files and Code of Practice (COP) standards. To receive a site entry permit or pass a contractor safety audit, you must present reliable, repeatable brake compliance certificates.

Brake IQ provides mobile testing units that visit your depot or yard to perform full dynamic brake tests. We analyze individual axle performance under dynamic load conditions, ensuring your safety files are audit-ready and your trucks stay on the road.

Why Interlinks Need Specialized Inspections

Standard dynamic brake tests only register the stopping force of the vehicle as a single unit. On a complex interlink, this can hide critical flaws:

  • Late trailer brake application forcing the truck-tractor forward, causing instability.
  • Chamber pressure imbalances between left and right wheels causing brake steer.
  • Uneven axle load distribution where one trailer does 80% of the braking.
  • S-cam binding or booster leaks that only show up under heavy load cycles.

What is Captured

[01]
Dynamic Deceleration:

Measures exact deceleration rate in m/s² during stopping cycles under full GCM load.

[02]
Axle-Level Force:

Identifies balance ratios and locking points on every axle of the interlink combination.

[03]
Pressure Build Logs:

Monitors air delivery timing and valve build-up speeds down the trailers.

COMPLIANCE FILE CHECKLIST
  • Dynamic Brake Deceleration Test Meets minimum 35% efficiency target (Regulation 157).
  • Pressure Imbalance Verification Confirm left-right chamber values match within 15%.
  • Response Lag Testing Measure trailer brake application delays.
Audit Compliance

Streamline Your Contractor Safety File Approvals

Safety officers do not want questionable declarations. They require detailed, auditable proof that contractor coal trucks are safe to operate on site.

Brake IQ reports compile all dynamic and static test parameters into a clean, professional PDF file that can be added directly to your safety files. Our unique online console allows mine auditors to instantly verify reports via a secure URL or QR code, removing approval bottlenecks.
