A mid-size cement plant operating three limestone quarries was losing an average of 14 hours per week to unplanned mobile equipment downtime — haul trucks sitting idle at the crusher, wheel loaders pulled from service without parts on hand, and pre-shift inspection defects discovered only after the operator was already in the cab. The maintenance team ran on paper inspection sheets, a whiteboard parts-on-order tracker, and a reactive repair culture where the same failures repeated every 6–8 weeks because work order history was never accessible to technicians in the field. Over nine months following the deployment of OxMaint's mobile CMMS platform, the plant reduced quarry mobile equipment downtime by 34% — from an average of 14 hours per week to 9.2 hours — by addressing three specific operational gaps: pre-shift inspection digitization, parts kitting tied to recurring failure codes, and supervisor visibility into open and overdue work orders from a mobile device. This case study documents exactly what changed, what the before-state looked like, and what other cement quarry operations can replicate.

The Before State — What 14 Hours of Weekly Downtime Looked Like
Before OxMaint, the quarry maintenance operation had the four characteristics that define a reactive maintenance culture. Identifying them accurately was the first step in building a targeted intervention.
1
Paper Pre-Shift Sheets With No Feedback Loop
Operators completed handwritten pre-shift checklists that were collected at the end of shift and reviewed by the supervisor the next morning — often 20+ hours after the defect was observed. Defects flagged on paper sheets were not automatically converted into work orders, so items rated "monitor" remained in a paper pile rather than a repair queue.
2
No Repair History Accessible to Field Technicians
Work order records from the previous quarter were in a filing cabinet in the maintenance office — not on the device a technician carried to a broken-down haul truck at the crusher pad. The result was repeated diagnosis time on recurring failures and parts runs for components already in the storage room because nobody could see the current inventory from the field.
3
Parts Ordered Reactively After Each Failure
The six highest-frequency repair codes — hydraulic hose replacements, tire inflation valve stems, air filter elements, brake pad sets, alternator drive belts, and pivot pin hardware — consumed 68% of all mobile equipment repair events. None of these were kitted or stocked predictively. Parts wait time averaged 4.2 hours per reactive repair event.
4
Supervisor Visibility Only From the Office
The maintenance supervisor could see the status of active repairs only by physically walking the quarry or calling technicians by radio. Work orders were assigned at morning briefing and not updated until the technician returned to the office — meaning delays, scope changes, and unexpected parts needs were invisible until the end of shift debrief.
The 3-Change Intervention — What OxMaint Deployed
The 34% downtime reduction did not come from a technology-first rollout — it came from identifying the three operational gaps with the largest impact and building OxMaint workflows around each one. All three were live within 6 weeks of deployment.
Change 01
Digital Pre-Shift Inspection With Auto Work Order Creation
Before
Paper checklist collected at end of shift. Defects reviewed 20+ hours after observation. No automatic escalation to repair queue.
After
OxMaint mobile pre-shift form completed by operator at cab. Any item rated "Action Required" auto-generates a work order assigned to the duty technician within 90 seconds of form submission. Supervisor receives notification on mobile. Photo evidence attached at point of discovery.
Result: average defect-to-work-order lag reduced from 20+ hours to under 2 minutes
Change 02
Recurring Failure Code Parts Kitting
Before
Top 6 repair codes each triggered a separate parts run. 4.2 hour average parts wait per reactive event. No parts pre-staging tied to equipment health signals.
After
OxMaint PM templates for each of the top 6 failure codes include a pre-built parts list. When a work order opens for those codes, the parts list auto-populates and the storeroom receives a pull notification before the technician arrives. Minimum stock levels for these 6 categories set and tracked in OxMaint.
Result: parts wait time on recurring repairs reduced from 4.2 hours to 38 minutes average
Change 03
Real-Time Supervisor Dashboard on Mobile
Before
Supervisor visibility required physical presence at the equipment or radio contact. Work order status unknown until end-of-shift debrief. Delays not visible until production meeting.
After
OxMaint supervisor mobile dashboard shows all open work orders with current status, assigned technician, time-in-queue, and parts pending flags. Supervisor can reassign, escalate, or add notes from mobile without returning to office. Works on LTE where quarry Wi-Fi is unavailable.
Result: inter-shift handover time reduced by 40 minutes per day — technicians start repairs, not briefings

Month-by-Month Progress — The 9-Month Downtime Curve
The downtime reduction was not linear. The first three months saw modest improvement as operators adopted the digital pre-shift form. The step-change happened in month 4 when parts kitting for the top failure codes was fully operational.
Months 1–2
Platform Deployment
OxMaint configured for 3 quarry sites. Equipment asset register built. Pre-shift forms deployed to operator devices. Supervisor dashboard activated.
Downtime: ~13.5 hrs/week (-4%)
Month 3
Adoption Stabilizes
Pre-shift completion rate reaches 94%. Supervisors using mobile dashboard daily. Work order backlog visible for first time — 47 open items identified and prioritized.
Downtime: ~12.8 hrs/week (-9%)
Months 4–5
Parts Kitting Live
Top 6 failure code parts kits stocked and integrated with work orders. Parts wait time drops immediately. Technicians spend time repairing, not driving to the storeroom.
Downtime: ~11.1 hrs/week (-21%)
Months 6–9
Sustained Improvement
Repeat failures on top 6 codes reduce as PM triggers catch wear before failure. Pre-shift defects addressed same-shift. Supervisor inter-shift debrief cut to 15 minutes.
Downtime: ~9.2 hrs/week (-34%)
Frequently Asked Questions
How long does OxMaint take to deploy across multiple quarry sites?
For a 3-site quarry operation with 15–40 mobile equipment assets, OxMaint is fully configured in 1–3 days including asset register setup, pre-shift form customization, and supervisor dashboard configuration. Free data migration support means existing equipment lists and PM schedules transfer without manual re-entry. Operators are typically completing digital pre-shift forms on day one of deployment.

Does OxMaint work in quarries without reliable Wi-Fi or cell coverage?
Yes — OxMaint mobile works in offline mode, allowing technicians and operators to complete work orders and pre-shift forms without connectivity. Data syncs automatically when the device reconnects to LTE or Wi-Fi. Pre-shift forms, work order updates, and photo attachments all queue locally and upload on reconnect, so quarry dead spots do not break the workflow.
What mobile equipment types does OxMaint support for quarry operations?
OxMaint supports any equipment type through configurable asset templates — haul trucks, wheel loaders, excavators, dozers, drill rigs, and support vehicles are all common quarry asset types managed on the platform. Each asset gets its own pre-shift inspection template, PM schedule, and work order history. Equipment from any manufacturer is supported since OxMaint is not brand-specific.

How does parts kitting work in OxMaint for recurring failure codes?
When a work order is created for a failure code that has a pre-built parts template, OxMaint automatically attaches the parts list to the work order and can send a pull notification to the storeroom. Minimum stock levels for kitted parts are tracked in OxMaint and generate reorder reminders when inventory drops below threshold. The storeroom team sees the parts request before the technician arrives at the workshop, cutting wait time significantly.
Can OxMaint handle pre-shift inspection compliance reporting for multiple quarry sites?
Yes — OxMaint generates pre-shift completion rate reports by site, equipment type, operator, and time period. Missed pre-shifts appear as overdue items in the supervisor dashboard. This reporting is particularly useful for operations where regulatory requirements mandate documented pre-shift inspections, since every completed form carries a timestamp, operator identity, and equipment identifier as an auditable record.
