Mining equipment maintenance is the planned inspection, service and repair of machines that move and crush ore. Haul trucks and crushers matter most. A stopped truck slows the pit, and a stopped primary crusher can starve the whole plant.

A Computerized Maintenance Management System (CMMS) gives maintenance teams one place to schedule hour-based services, track component life, control critical spares and prove results. This guide covers how haul trucks and crushers fail, how to schedule their work, and how a CMMS supports mining equipment maintenance for both.

Key Takeaways

  • Criticality first: Haul trucks and primary crushers carry the highest cost of failure, so they get the tightest plans.
  • Usage beats the calendar: In mining equipment maintenance, haul trucks need service by operating hours, while crushers need plans driven by tonnes, wear and condition readings.
  • Spares decide downtime: Liners, bearings and major components need reorder points, because long lead times turn small faults into long stoppages.
  • A CMMS ties it together: Hour-based PMs, offline mobile work orders, downtime tracking and parts alerts keep both asset types on plan.

What Is Mining Equipment Maintenance?

Three mining maintenance strategies: reactive, preventive and condition-based | Cryotos

This work covers every task that keeps mobile and fixed mine assets running safely, from daily walk-arounds to planned plant shutdowns. Most mining operations combine three strategies.

  • Reactive maintenance: Fix the machine after it fails. This is the costliest option for critical assets.
  • Preventive maintenance: Service machines by operating hours or calendar dates, whichever comes first.
  • Condition-based maintenance: Act on oil analysis, vibration, temperature or power-draw readings before a fault becomes a failure.

ISO 55000 frames maintenance as one part of managing an asset across its life. Reliability-centered maintenance (RCM) then helps maintenance teams match each strategy to the way a component fails.

Teams that do this well rank assets by criticality first, then set the plan, and they build permits for isolation, lifting and hot work into every job. Give each asset the strategy it deserves.

Haul Truck Maintenance: Systems, Failures and PM Intervals

Haul truck maintenance centers on the systems that cause most stoppages: engine and cooling, drivetrain, hydraulics, tires, and frame. Rigid-frame haul trucks in the 100 to 400 tonne payload class usually run in large fleets, so one idle unit slows the whole haul cycle.

Which haul truck systems fail most often

  • Engine and cooling: Overheating, injector wear and turbocharger faults. Oil and coolant sampling catch trouble early.
  • Drivetrain: Transmission, final drive and differential wear. Teams track component hours and plan exchanges before failure.
  • Hydraulics: Cylinder leaks, pump wear and hose failures. Contamination control protects every pump and valve.
  • Tires: Cuts, heat damage and overloading. Tires are often a top consumable cost, so pressure and life tracking pay back fast.
  • Frame and body: Fatigue cracks and liner wear. Regular crack inspections prevent structural failures.

What a haul truck pre-shift inspection should cover

  • Tires and wheels: Look for cuts, bulges and low pressure.
  • Fluids and hoses: Check levels and look for leaks at hydraulic and cooling connections.
  • Brakes and steering: Test response before the truck leaves the shop or park-up area.
  • Body and frame: Look for cracks, loose liners and damaged guards.
  • Warning lights and fault codes: Record active codes, so the workshop sees them.

How to schedule haul truck PMs

Usage-based maintenance is a schedule that triggers work when a machine reaches set operating hours. Most haul truck programs pair a daily pre-shift inspection with tiered services, commonly at 250, 500, 1,000 and 2,000 hours, though each OEM sets its own intervals.

Cryotos preventive maintenance software supports static and dynamic PMs, including triggers by hours, so each truck's service falls due at the right time.

How to track haul truck component life

Engines, transmissions and final drives run to target hours. Record hours-to-date against the target on each asset, log every exchange, and review early failures with the supplier. That history also supports warranty claims.

Crusher Maintenance: Liners, Lubrication and Reline Shutdowns

Crusher maintenance revolves around liner wear, lubrication health and planned shutdowns. Primary gyratory and jaw crushers rarely have a spare, so a stoppage can starve everything downstream.

What to monitor on a crusher

  • Liners: Measure the wear profile and plan the reline by tonnes or running hours, not by surprise. Record the reading at every change-out to refine the next interval.
  • Lubrication: Track oil temperature, pressure and filter condition. A rising temperature or clogged filter often comes before a bearing fault, and oil analysis flags wear early.
  • Drive train: Check motor, belt and coupling alignment. Thermography and vibration readings catch faults before they escalate.
  • Feed and discharge: Watch for tramp metal, blockages and chute wear, and verify the closed-side setting (CSS), the smallest gap between liners at discharge.

How to plan a crusher reline shutdown

  • Build the job plan early: Start weeks ahead, with tasks, labor, tools and lifting equipment defined.
  • Confirm liner sets on site: Check stock and condition before the shutdown window opens.
  • Control safety: Mine safety rules, including MSHA machinery standards in the US, require power off and blocking before repairs begin.
  • Record the result: Log wear, hours and tonnes at change-out to set the next reline date.

A critical spare is a high-value part that stops a machine or circuit when it fails and takes weeks to replace. For crushers, that means liner sets, bearings and lube pumps. Strong spare parts management gives each one a minimum stock level and alerts the team before it runs out.

Haul Trucks vs Crushers: Maintenance Comparison

Haul trucks need usage-based, fleet-wide maintenance, while crushers need condition-based, plant-level planning. The table shows where the two differ most.

DimensionHaul trucksCrushers
Asset typeMobile, many similar unitsFixed plant, often a single unit
Main triggerOperating hours and component lifeRunning hours, tonnes and condition readings
Largest wear costTires, major components, body linersLiners, bearings, lubrication health
Planned eventsTiered PM services and component exchangesLiner changes and scheduled shutdowns
Safety focusIsolation, tire handling, working at heightLockout, confined space, heavy lifting
Key dataHours, payload, fault codes, oil samplesPower draw, vibration, temperature, liner wear

Both asset types share one need in mining equipment maintenance: a single record of work, parts and downtime. That record helps teams spot repeat failures and plan shutdowns around real data. It also clarifies ownership: a fleet planner usually owns the trucks, while a plant planner owns the crushing circuit.

How a CMMS Improves Mining Equipment Maintenance

Six CMMS capabilities for mining equipment maintenance | Cryotos

A CMMS replaces paper, spreadsheets and memory with scheduled work, live asset history and parts alerts. Six capabilities matter most for haul fleets and crushing circuits.

  • Hour-based PMs: Dynamic schedules trigger services by operating hours, and customizable checklists, built from Excel files or scanned with OCR, cover pre-shift inspections.
  • Offline mobile work orders: Technicians log work at remote pits and plants without signal, and the app syncs when the device reconnects.
  • Downtime data: Real-time tracking by asset reports MTTR, MTBF and availability, while 5 Whys root cause analysis targets repeat failures.
  • Spare parts alerts: QR and barcode stock visibility with minimum-threshold alerts protect liners, filters and exchange components.
  • IoT meter readings: SCADA, PLC and edge connections bring meter and condition readings into the system.
  • Permit-to-Work: Isolation, lifting and hot-work permits sit alongside the job they protect.

Maintenance teams using Cryotos have reported up to 30% reduction in unplanned downtime and 25% faster repair turnaround. See how Cryotos delivers maintenance software built for mining operations, from haul fleets to crushing circuits.

What this looks like in practice at a mine

A planner schedules the 1,000-hour service for truck HT-214, attaches the checklist and parts list, and assigns the work order. The technician completes it on a phone, and parts used are recorded against the job. The next service then falls due from the new hour reading.

The Pit-to-Plant Uptime Framework

The Pit-to-Plant Uptime Framework: rank, trigger, plan, stock, prove | Cryotos

A pit-to-plant approach to mining equipment maintenance works when it follows five steps: rank, trigger, plan, stock and prove. Use the same steps for trucks and crushers.

The Pit-to-Plant Uptime Framework:

  • Rank: Score every truck and crusher by safety, production and repair-cost impact, then focus effort on the top tier. A primary crusher with no spare usually outranks one truck in a fleet of thirty.
  • Trigger: Start work by operating hours, tonnes or condition readings instead of calendar dates alone.
  • Plan: Build job plans, checklists and shutdown scopes before the machine goes down, including permits and labor.
  • Stock: Give critical spares minimum levels, lead times and named owners.
  • Prove: Review availability, MTBF, MTTR, PM compliance and planned-versus-unplanned work every month.

Availability is the share of scheduled time a machine can operate. PM compliance is the percent of due PMs finished on time. Together with MTBF and MTTR, they show whether your mining equipment maintenance plan works.

What to do in the first 90 days

  • Weeks 1 to 2: Rank assets and baseline availability, downtime and PM compliance.
  • Weeks 3 to 6: Load the asset hierarchy, PM templates, checklists and critical spares for one truck segment and one crushing circuit.
  • Weeks 7 to 12: Run live work orders, review KPIs weekly and compare results with the baseline.

Frequently Asked Questions

How often should a mining haul truck be serviced?

Most haul trucks follow a daily inspection plus tiered services at operating-hour intervals, commonly from 250 to 2,000 hours. Your OEM manual sets the exact intervals, and a CMMS can trigger each service automatically by hours.

How do you track crusher liner wear in a CMMS?

Measure the liner profile at set intervals, record tonnes or running hours at each change-out, and log the results against the crusher. Over time, that history shows the right reline interval.

Can a CMMS work at remote mine sites with poor connectivity?

Yes, if the mobile app has an offline mode. Cryotos lets technicians complete work orders and checklists without signal, then syncs the data automatically when the device reconnects.

Does a CMMS replace OEM telematics and condition monitoring?

No. OEM tools produce machine data, while a CMMS turns that data into scheduled work, parts and records across every make and model. Cryotos also supports IoT meter readings through SCADA, PLC and edge connections.

What KPIs should mining equipment maintenance teams track?

Start with availability, MTBF, MTTR, PM compliance and the ratio of planned to unplanned work. Add component life against target for trucks, and liner life in tonnes or hours for crushers.

Which CMMS features matter most for mining fleets?

Look for hour-based PM triggers, offline mobile work orders, spare parts alerts, downtime tracking and Permit-to-Work. Those five cover most haul truck and crusher needs.

How far ahead should you plan a crusher reline?

Start the job plan weeks ahead, confirm liner sets and lifting equipment, and book contractors and permits early. Exact lead times depend on liner supply and site rules.

Haul trucks and crushers reward teams that plan mining equipment maintenance by usage and condition, not by failure. Schedule a free demo to see how Cryotos keeps mining fleets and crushing circuits on schedule.
