How Haul Truck Bin Shape Impacts Productivity and Haulback in Mining Operations
The haul truck bin shape can significantly affect mining and quarry operations, often causing haulback or carryback that reduces truck productivity. Bins with suboptimal shapes retain material after unloading, creating an overstatement of haul truck production. While the numbers may appear higher, the actual material moved is often less, increasing costs per tonne.
What is Haulback and Why It Matters
Haulback occurs when material sticks to the truck bed after unloading. Over time, this reduces efficiency, skews production data, and increases operational costs. This issue is common in bulk material transport, including aggregates, ore, and construction fill. Accurately monitoring haulback is critical to maintaining truck payload efficiency and ensuring correct production reconciliation.
How Loadscan 3D Payload Profiling Helps
The Loadscan 3D Payload Profiler provides a visual representation of load distribution and accurate volumetric measurements. Operators can identify haulback and monitor bin performance to optimize efficiency.
Key Steps in the Load Profiling Process:
Trucks are fitted with an RFID tag for automatic identification.
Trucks are scanned empty to establish baseline statistics.
After loading, trucks drive under the scan head to capture volume measurements.
Trucks can be scanned on return trips to detect haulback or carryback, which is then removed from shift tallies.
3D load profiling helps assess bin performance and determine when bins require cleaning.
Benefits of Optimizing Haul Truck Bin Shape
Improved payload accuracy
Better truck productivity tracking
Reduced material waste
Lower cost per tonne
Enhanced operational efficiency
By addressing inefficiencies caused by haul truck bin shape, mining operations can gain more accurate production data and make informed decisions on truck and bin maintenance.
Optimizing the haul truck bin shape isn’t just about truck design—it’s about using technology like Loadscan to enhance efficiency, reduce haulback, and ensure every haul counts. With 3D load profiling, operators can monitor bin performance, prevent production shortfalls, and maintain a cost-effective operation.
