Stand next to a 400-tonne haul truck and every sense of scale flips. The machine is enormous. The sensor now catching hazards for that machine is barely bigger than a shoebox. That contrast tells you almost everything about where haul road management is heading.

We’ve spent years watching mine sites instrument crushers, conveyors and pump stations down to the smallest vibration, while the ground the entire fleet drives on gets almost no real-time attention. It’s a strange blind spot. The haul circuit carries every tonne a site produces, yet for decades it’s been assessed by someone in a light vehicle making a judgement call, or a drone flying over twice a day. Neither method sees the surface the way a fully loaded truck experiences it, and that gap is exactly where premature tyre failure, unplanned downtime and safety risk take root.

 

The Real Cost Hiding Underfoot

Most haul truck tyres fail well before they should, and the industry has quietly accepted that as the cost of doing business. It doesn’t have to be. When trucks themselves scan the surface continuously, using high-resolution light and camera detection mounted directly on the haulage fleet, hazards get flagged the moment they appear rather than after a tyre is already damaged. That single shift, from periodic inspection to continuous measurement, changes the maths on tyre life, fuel burn and grader dispatch all at once.

The results back this up. Testing has recorded a 60 per cent reduction in tyre-rock impacts, tyre life gains of up to 20 per cent, and a 4 per cent lift in truck availability. On an asset class where a single ultra-class tyre can run into six figures, those percentages compound fast across a fleet running continuously, every shift, every truck.

 

Safety Sits Underneath Every Number

Tyre handling is among the most hazardous maintenance tasks on a mine site, so every rock impact avoided is one less high-risk intervention a crew has to perform. The same sensing layer also watches bund wall geometry at tip heads, catching non-compliance before a truck backs up to it. Fewer hazards on the circuit means fewer dangerous jobs off it, and audit-ready evidence instead of a judgement call.

 

Why This Matters More As Fleets Automate

Autonomous haul trucks don’t have a driver’s instinct about which bumps are worth ignoring. They’re programmed for caution, so an irregularity a human would barely notice can stop an unmanned truck in its tracks, and a stopped truck moves no ore. Battery-electric haulage carries the same weakness in a different form: rolling resistance on a degraded surface drains range fast, quietly shortening how far a truck can run before it needs to recharge. Neither future works on a circuit nobody is actually measuring.

That’s the case we’ve built our business around. Preventive action beats reactive investigation every time, and the haul road is the one asset that’s historically carried the least data despite carrying the most value.

 

Where To Next

Mining has spent a decade chasing the visible shifts: automation, electrification, digital twins of entire pits. We’d argue the more consequential change is smaller and sits underfoot, in the ground the fleet actually drives on, now watched the way everything else on site already is.
