Mining vehicles live a hard life. Haul trucks, wheel loaders, electric rope shovels, water trucks, graders, and underground LHDs run long shifts in dust, heat, cold, and vibration that few other industries inflict on capital equipment. A single 400-ton haul truck can cost thousands of dollars per hour when it sits idle, and the ripple effects to the pit, crusher, and mill compound that quickly. A CMMS is the operational system that keeps a mining fleet in productive service rather than in the workshop.
According to Deloitte’s “Digital Transformation in Mining” research, maintenance represents 30 to 50 percent of total operating expenditure at most mining sites, and 60 to 80 percent of equipment problems originate from poor maintenance practices. Those two numbers frame why CMMS discipline matters in mining more than in almost any other vertical.
What the CMMS holds for a mining fleet
Asset register built around the heavy fleet hierarchy
Every piece of mobile equipment is recorded in the asset register with OEM, model, serial, commissioning date, cumulative hours, payload class, tire size, drivetrain type, and the parent pit or section it works in. Engines, transmissions, final drives, hydraulic pumps, and tires are tracked as their own child components so their lives can be managed independently of the chassis. When a haul truck swaps engines at overhaul, the CMMS transfers the old engine’s history to a rebuild record and starts fresh meter readings on the new unit.
Meter-based and calendar-based PM scheduling
Mining PM programs mix engine hours, odometer miles, cycle counts, and time. The CMMS ingests meters from telematics (Caterpillar Vital Information Management System, Komatsu KOMTRAX, Modular Mining DISPATCH) and triggers preventive maintenance work orders at 250, 500, 1,000, and 2,000 hour intervals. A properly tuned PM library covers engine oil and filters, hydraulic oil sampling, greasing, wheel station inspections, brake wear, suspension strut pressure, differential oil, cooling package cleaning, and structural crack checks.
Backlog and repair execution
Operators write defect reports from the cab; the CMMS turns those defects into work orders routed to the workshop. Planners assess severity, parts availability, and scheduled shutdowns, then build the day’s plan around equipment availability targets. Field service technicians pick up jobs from a mobile device, log labor and parts, and close the work order before the equipment returns to the pit.
Parts, tires, and consumables
Mining parts management is different because the parts are enormous, expensive, and often long lead time. The CMMS links parts to equipment so the parts and inventory module knows a 33.00R51 OTR tire or a ball joint kit is committed against a specific truck’s upcoming rebuild. Min-max triggers and vendor lead times protect availability; serial-tracked components such as engines and transmissions have complete rebuild histories attached.
Typical outcomes operators report
- 10 to 20 percent increase in mechanical availability across the haul fleet
- 15 to 30 percent reduction in emergency repair hours once a disciplined PM program is running
- 5 to 10 percent extension on major component life (engines, final drives, frames)
- 20 to 40 percent faster parts issue and kit-out on planned rebuilds
- Measurable drop in repeat defects because every fix is recorded against the asset
- Cleaner audit trails for warranty claims against OEMs and component rebuilders
These numbers align with Deloitte’s observation that predictive and planned maintenance in mining lifts uptime 10 to 20 percent and cuts costs 5 to 10 percent.
Surface versus underground considerations
Surface mines run a relatively standardized heavy fleet. The CMMS primarily coordinates open-pit haul cycles, so dispatch and workshop scheduling are the key integration points.
Underground mining introduces LHDs, jumbos, roof bolters, personnel carriers, and utility vehicles operating inside ventilation and ground-support constraints. The CMMS safety and compliance module enforces pre-start inspections, records isolation and tagout on electrical and hydraulic systems, and keeps a full history of fire suppression system service intervals, which are regulatory in most jurisdictions.

Frequently Asked Questions
Can a CMMS replace OEM telematics like VIMS or KOMTRAX?
No, and it shouldn’t try. OEM telematics are the best source for engine and drivetrain data. The CMMS consumes that data through integrations or CSV imports and turns it into PM triggers, fault records, and component history.
How are tires managed in a mining CMMS?
Each tire position on the truck is a serialized component. The CMMS records install date, position, hours, rotations, repairs, and scrap reason. Tire inventory is managed against the truck fleet’s projected consumption.
What about component exchange programs?
Major components (engines, final drives, converters) are tracked by serial number. When a unit is pulled for rebuild, the CMMS creates a rebuild work order with a parts kit, captures machining and inspection findings, and reissues the component with a new in-service date on whichever truck receives it.
Does a CMMS help with warranty recovery?
Yes. OEM warranty claims require a complete service history, correct fluids, and documented inspection intervals. A well-kept CMMS is the single source of truth when you need to defend a claim against an engine, drivetrain, or frame manufacturer.
What integrations are typical for a mine CMMS?
Equipment telematics, dispatch systems (Modular, Wenco, MineStar), ERP parts and purchasing, fuel management, and shift reporting. Integrations cut double entry and keep the CMMS in step with the pit.
Strong mining operations make PM compliance, parts availability, and component history non-negotiable. Book a Task360 demo to see the discipline applied to your own haul fleet and support equipment.
