A carton that survives a lab drop test can still arrive crushed if the trailer, route, or stacking pattern was harsher than assumed. ISTA procedures give shippers and carriers a shared language for testing packages against distribution stress. Thi
Oxmaint is a maintenance management software (CMMS) that helps fleet managers, transportation carriers, delivery operators and heavy equipment fleet owners run work orders, mileage-based preventive maintenance, DVIR inspections, tire and part inventories, warranty tracking and DOT-ready compliance records for every vehicle and every trailer from one platform.

From paper DVIRs and disconnected spreadsheets to one CMMS covering every unit, part and compliance record — without pulling vehicles off the road.
Import every vehicle, trailer and machine by VIN and odometer.
Set mileage, hours and calendar PM per class, load DVIR templates.
Odometer, engine hours and fuel-card cost update automatically.
Cost per mile, PM compliance and uptime, with DOT-ready packs.
Drivers file DVIRs on mobile before leaving the yard, and any defect instantly opens a work order on the mechanic's bay tablet. Mark a brake defect on a post-trip DVIR and Oxmaint flags the tractor out-of-service, reserves the parts and holds it from dispatch until a mechanic closes the job with photo evidence and an e-signature.

Every vehicle is registered by VIN, plate, model and class with warranty and PM intervals attached. Tires track by position, tread depth and install mileage; batteries by install date and cycle count. Every part swap, top-up and warranty claim writes to the vehicle's history — so whether Truck #47's tires need rotation or retirement takes seconds to answer.

Every unit gets its own trigger set: A-service at 15,000 miles, B-service at 45,000, hours-based intervals for off-highway machines. When a tractor approaches 50,000, Oxmaint generates the B-service work order the day before the threshold, reserves the parts kit and assigns the bay — and the closed record moves into that VIN's DOT compliance file, exportable in the format an FMCSA audit needs.

Work orders, mileage-based PM, VIN registers, tire and part inventories, digital DVIRs, predictive alerts and DOT compliance records in one CMMS.
Every DVIR defect, scheduled PM and corrective repair in one shop queue — bay assignment, mobile execution, photo evidence.
Mileage, engine-hour, calendar and deadline PM per vehicle class — WOs generate at threshold with parts kits and bay assigned.
Every tractor, trailer, van and heavy equipment unit by VIN, plate, class and warranty — one lookup opens full service history.
Filters, belts, brake pads, tires and batteries across shop storerooms — min-max levels and reservation on every PM.
Pre- and post-trip DVIR checklists on the driver's phone — defects auto-create a WO and hold the vehicle out-of-service.
Fault codes and telemetry ingested so engine, transmission and after-treatment drift becomes a WO, not a dashboard alarm.
DVIRs, annual DOT inspections, roadside reports and safety sign-offs captured as FMCSA-ready packs by unit or driver.
Cost per mile, PM compliance, DVIR pass rate and uptime — filter by unit, class, driver or garage.
A long-haul carrier, a last-mile van operator, a construction fleet on engine hours and a rental operator — four typical deployments.
The Situation
A long-haul carrier ran Class 8 tractors across a multi-state network of garages. Paper DVIRs sat in cab booklets for weeks, mileage PM lived in spreadsheets that never matched dispatch, and DOT audit prep meant days of file-hunting.
How Oxmaint Helped
Every tractor and trailer was registered by VIN. Drivers filed DVIRs on mobile, defects auto-flagged the unit and opened a shop WO, mileage PM triggered at threshold, and audit packs exported by VIN in minutes.
One CMMS record
Driver app to shop
Audit packs in minutes
Every tractor and trailer catalogued by VIN, model, class and warranty, replacing spreadsheets that never agreed.
Drivers completed DVIRs on mobile — any defect flagged the unit out-of-service and opened a WO for the next garage.
A, B and C intervals per tractor class — WOs generated and parts reserved at the threshold, not after a breakdown.
Annual inspections, roadside reports and DVIR history attached to each VIN, exportable by unit or date.
The Situation
A last-mile operator ran hundreds of cargo vans across metro zones. Mileage piled on fast and PM slipped, peak-season breakdowns cascaded into route failures, and with drivers rotating only the last mechanic knew a van's history.
How Oxmaint Helped
Every van carried a QR label in the cab, so any driver could open its full history from their phone. Mileage PM ran continuously, and fleet-wide analytics showed which units were breaking economics.
QR-tagged, tracked
Mileage triggers
Uptime protected
A QR sticker in every cab — scan to see the van's service history, warranty status and open work orders.
Odometer data from telematics meant PM triggers never relied on driver memory, whatever the rotation.
Every intervention accumulated, backing retire-vs-refurbish calls with real spend and downtime data.
Cost per mile, uptime and repair frequency compared van-to-van, surfacing which units eroded route economics.
The Situation
A construction fleet ran excavators, loaders and mixers across multiple job sites. Machines ran on engine hours not miles, moved between projects untagged, PM logs sat in a paper notebook, and a down excavator delayed whole projects.
How Oxmaint Helped
Every machine was QR-tagged with its engine-hour PM intervals. Operators updated hour readings on mobile, and equipment carried its full history between sites — so arriving mechanics knew what was due.
QR-tagged
PM triggers
History follows equipment
Each excavator, loader and mixer carried its own hour-meter thresholds, matching real wear not a spreadsheet estimate.
Operators and travelling mechanics scanned a QR label on any site for hour readings, past service and open WOs.
Repairs and PM travelled with the equipment — no history lost when a loader moved to another project.
Hydraulic fluids, filters and cutting edges tracked with automatic reservation on every hours-based PM.
The Situation
A rental operator managed hundreds of cars, vans and trucks across multiple locations. Every cycle demanded fast inspection turnaround, damage claims were fought without documentation, and utilisation targets pushed PM slippage.
How Oxmaint Helped
Every unit was registered with pre- and post-rental inspection checklists. Staff completed digital condition checks on mobile with photo evidence, and PM ran regardless of utilisation pressure.
Digital inspections
Damage documented
PM discipline
Pre- and post-rental checklists ran on mobile, capturing tire tread, body condition and interior wear in photos.
Condition in and out of each cycle captured with time-stamped photos, backing claims with before-and-after evidence.
Mileage-based PM ran on schedule regardless of rental demand, protecting resale value instead of deferring service.
Each location its own site — regional managers saw utilisation, condition scores and PM compliance in one dashboard.
Odometer, engine hours and fault codes update automatically from telematics, with fuel-card feeds for cost and ERP integration across every garage.
Explore All IntegrationsLong-haul carriers running Class 8 tractors, last-mile van fleets, construction fleets with off-highway equipment, and rental and leasing operators. Mileage, engine-hour and calendar PM run side-by-side, so one deployment covers on-highway vehicles, equipment and trailers in a single register.
Yes. Mileage-based (A, B and C thresholds), engine-hour based, calendar-based and deadline-driven triggers all run — often layered on the same unit. Every task auto-generates a work order with linked parts kit and assigned mechanic.
Yes. Drivers complete DVIR checklists before pulling out and at end-of-shift. Any defect flags the vehicle out-of-service and opens a corrective work order, holding the unit from dispatch until a mechanic closes it with photo evidence and an e-signature — all captured against the VIN.
Yes. DVIRs, annual DOT inspections, roadside reports and shop safety sign-offs attach to the vehicle VIN as immutable evidence. When an FMCSA auditor or insurance adjuster asks, filter by VIN, date or driver and export a complete audit pack in seconds.
Yes. Telematics providers push odometer readings, engine hours and fault codes into the CMMS automatically, driving mileage-based PM without manual meter entry. Fuel-card feeds bring consumption and cost in, so cost per mile and MPG appear in dashboards, and ERP integrations move cost data without re-keying.
Yes. Every vehicle carries life-cycle records for tires (position, tread depth, install mileage), batteries (install date, cycle count) and warranties with expiry alerts. Each part swap and claim writes to the unit's history — so whether Truck #47's tires need rotation or retirement is answered instantly.
