Grader Performance Monitoring for Mine Road Maintenance
Grader Performance Monitoring from Proof Engineers tracks where graders work, how long blades are down, and how effectively road maintenance is being carried out. The system replaces guesswork with verified blade-down data and performance metrics for each shift.
What is Grader Performance Monitoring?
Grader Performance Monitoring helps mine teams measure grader activity, blade-down time, productivity and coverage across mine road maintenance areas. The system gives supervisors and planners objective data on motor grader performance instead of relying on engine-hour metrics or informal shift reports alone.
For teams managing haul road maintenance, GPM answers practical questions: where did graders work, how much of the shift was productive blade-down time, and how did activity align with road maintenance priorities?
Why grader productivity is hard to measure manually
- Large operating areas make it difficult to verify where graders actually worked
- Inconsistent manual reporting between crews and shifts
- Engine-hour metrics that do not reflect productive blade-down grading
- Limited ability to link grader activity to road condition outcomes without objective data
The GPM Workflow

Install
Installation is fast and versatile. The GPM unit is fully weatherproof and housed in a heat and debris protection unit. We offer multiple mounting options, including magnetic or bolt-on, to suit any grader turntable.

Monitor
Gain real-time visibility into grader activities. Monitor blade-down locations and work intensity with colour-coded mapping—green for productive grading and red for non-productive travel.
Live Fleet Visibility
See your entire grading fleet's status in real time. Know exactly where each grader is working and whether blades are down—replacing manual checks with real-time visibility.

Report
Target maintenance where it matters, and track long-term ROI with automated reports and trend analysis.
Targeted Maintenance
RCM integration directs operators to priority zones. Eliminate arbitrary grading by focusing blade-down time on high-roughness areas that need it most.
Trend Analysis
Track ROI and long-term road health improvement. Historical data reveals sustained efficiency gains and quantifies the value of your grading investment.
What Proof Engineers tracks
Based on the GPM system capabilities already deployed on site, teams can review:
- Grader activity — location-based coverage and work intensity on maps
- Blade-down time — productive grading versus non-productive travel
- Productivity — effective utilisation as blade-down time versus total active time
- Grader Efficiency — whether graders prioritised roads that RCM data shows need maintenance
- Performance over time — automated reports and trend analysis for shift and weekly review
Blade-down monitoring
Blade-down monitoring matters because it distinguishes productive road maintenance from travel and idle time. A grader can be active for a full shift while only part of that time involves the blade working the road surface.
GPM tracks blade-down locations and intensity so supervisors can see grader utilisation based on verified activity, not assumptions from engine hours or end-of-shift summaries.
Activity, productivity and coverage
Activity shows where a grader travelled and operated across the network. Coverage shows the extent of that movement relative to roads that need attention.
Productivity goes further—it measures how much of active time was spent in productive blade-down grading versus non-productive travel. That difference is central to grader productivity monitoring and fair performance review.
Key Performance Metrics
Metrics for grader activity monitoring, blade-down monitoring and mine road maintenance performance.
Productivity - aka Effective Utilisation
Track grader productivity monitoring as the exact ratio of time spent blade-down versus total active time.
Efficiency
The GPM system utilises road condition data from the RCM system to determine whether graders are prioritising roads that actually require maintenance. We refer to this as Grader Efficiency.
Visual Intensity Mapping
Green pixels show exactly where graders have worked, with shades indicating the intensity of grader activity monitoring and work performed.
Fleet Rationalisation
Use verified blade-down and utilisation data to right-size your fleet. Reduce the number of graders required to meet budget without sacrificing road quality.
How GPM works with Road Condition Monitoring
Road Condition Monitoring identifies which haul road sections are deteriorating and need maintenance. Grader Performance Monitoring shows how graders responded—where they worked, blade-down time, and whether effort was focused on priority areas.
When both systems are in use, Grader Efficiency compares grader activity against RCM road condition data so teams can review mine road maintenance monitoring from identification through to execution.
Use cases
- Maintenance planning — align grader deployment with road condition priorities
- Grader allocation — review utilisation and right-size fleet based on verified blade-down data
- Shift review — compare productive grading versus travel after each shift
- Supervisor reporting — replace subjective summaries with objective activity maps
- Road maintenance performance review — track trends in productivity and efficiency over time
