Free CMMS for Mining and Aggregates
Log shifts, track OEE on crushers, conveyors and screens, and turn big single stops into work orders. Free, no account, and it runs right in your browser.
The short answer
- OEE Lab is a free CMMS and OEE tracker for mining and aggregates. Log each shift in about two minutes and see availability, performance and quality per machine.
- It runs browser-local on one device with no account and no cost, so a pit or plant crew can start on the next shift without IT or a signup.
- You get a downtime Pareto, a work order board, PM schedules and an asset register for crushers, conveyors, screens and mobile plant, plus CSV and JSON export you own.
- When one plant is not enough and you need PLC-read OEE, automatic micro-stop root cause and auto-routed work orders, Fabrico is the EU-built, ISO 27001 certified upgrade.
In mining and aggregates, a single stop on the primary crusher, a torn conveyor belt or a blinded screen can idle the whole line for hours, so the numbers that matter are uptime and throughput per machine. A free OEE tracker gives crews a shared, honest picture of where those hours go. If your team is still arguing over definitions, what OEE is and the real cost of downtime are the two ideas worth aligning on first.
OEE Lab is a free, browser-local CMMS built around 2-minute shift logging. Log run time, planned stops and unplanned stops and it computes availability, performance and quality plus a downtime Pareto that ranks your biggest losses. From there you raise a job on the work order board and keep a maintenance history, the same core you would expect from any free CMMS, with nothing to install and no account to create.
Being honest, the free tool is deliberately light: one plant, one device, manual logging, and you investigate causes yourself. Those limitations are fine for a single pit or plant, and this page is clear about when to upgrade to something that reads your PLCs and spans sites. It sits alongside the rest of our free manufacturing software so you can start today and grow later.
What you get, free
Two-minute shift logging
At shift end, log run time and the stops that hurt: crusher chokes, belt tears, screen blinding and mobile-plant faults. No sensors or setup, so the pit or plant crew can start on the very next shift.
OEE with availability, performance, quality
See A, P and Q for each asset so a crusher that runs slow is not hidden behind one that sits idle. The per-machine breakdown shows exactly which unit is dragging plant throughput down.
Downtime Pareto
Every stop reason is ranked biggest-first, so you can see whether liners, belt splices or screen media are eating the most hours this month and where a fix pays back fastest.
Work orders, PM schedule and asset register
Raise a work order off a stop, keep preventive maintenance schedules for crushers, conveyors, screens and mobile plant, and hold a simple asset register with people and roles on one device.
Export and backup you own
Everything lives in your browser. Export to CSV and JSON any time and use backup and restore to move data or keep a copy, so your maintenance log is never locked in.
Benchmark, PDF report and scorecard
Compare your OEE against reference benchmarks, print a clean PDF for the morning meeting, keep an on-screen scorecard, and install as a PWA so it opens like an app on a control-room tablet.
Log one shift and the free tracker shows your OEE, your loss Pareto and how you compare to world-class. Add work orders and preventive-maintenance reminders in the same place.
Where free stops, and Fabrico begins
The free tracker is built for getting started fast and for one plant on one device. When a site gets serious about its losses, the manual steps start to cost more than they save. This is exactly where Fabrico takes over.
| Capability | Free OEE Lab tracker | Fabrico |
|---|---|---|
| Data capture | Manual 2-minute shift logging, one entry per shift on one device. | PLC-read OEE captured automatically from the line, with no manual tally. |
| Loss-to-fix loop | You spot a big stop in the Pareto, then raise a work order by hand. | Closed loop: an OEE loss auto-routes a work order to the right crew. |
| Micro-stop root cause | You investigate short stops yourself from logged notes. | Computer vision finds the true cause of micro-stops with video evidence. |
| Scope and multi-site | One plant on one device or browser, with no sync between sites. | Many pits, plants and sites in one place with shared reporting. |
| Integrations | Standalone; move data in and out via CSV and JSON export. | Reads directly from PLCs to feed OEE and work orders. |
| Access and roles | People and roles on a single shared device or browser. | Accounts and role-based access for teams across sites. |
| Data residency | Data stays in your browser on your device. | EU-built with EU data residency. |
| Reporting | Benchmark comparison, downtime Pareto, printable PDF and on-screen scorecard. | Cross-site dashboards and trend reporting that supports audit-readiness. |
| Big stops and high-wear plant | Log major crusher, belt and screen stops and PM high-wear parts like liners and media by hand. | Automatic OEE capture across fixed and mobile plant, even at high stop frequency. |
Frequently asked questions
Is OEE Lab really free for mining operations?
Yes. The tracker is free, runs in your browser, and needs no account or install. You can log shifts, track OEE and raise work orders on the next shift at no cost.
Can it track crusher, conveyor and screen uptime together?
Yes. Add each crusher, conveyor and screen as an asset, log stops per machine, and the per-machine breakdown shows which unit is dragging plant OEE down.
Do I need sensors or a PLC connection?
No. Logging is manual and takes about two minutes a shift, so it works on mobile plant and remote pits with no wiring. If you want automatic PLC-read capture, that is where Fabrico comes in.
Where is my data stored?
In your browser on the device you use, not on our servers. Export to CSV or JSON any time and use backup and restore to keep a copy or move to another device.
When do I need more than the free tool?
When one plant on one device is not enough: you want many sites in one place, automatic OEE read from PLCs, computer-vision root cause of micro-stops, or auto-routed work orders. That is when teams move to Fabrico, the EU-built, ISO 27001 certified upgrade.
Can I use it instead of spreadsheets?
Yes. It replaces a shift-log spreadsheet with structured OEE, a downtime Pareto and a work order board, and still exports to CSV so you keep the flexibility spreadsheets gave you.
When free is not enough, Fabrico is the upgrade
OEE Lab is deliberately light so a single pit or plant can start today. When you outgrow one device and manual logging, Fabrico is the honest next step. It reads OEE straight from your PLCs and closes the loop by auto-routing a work order the moment a loss appears, uses computer vision to pin the true cause of micro-stops with video evidence, and runs EU-built with EU data residency and ISO 27001, 20000-1 and 9001 certification.
