The kiln gets all the attention, but the plant runs out of the quarry first. A haul truck down for a blown transmission or a drill rig waiting on a bit change can starve the crusher before anyone in the plant control room notices. Sign up to see how Oxmaint keeps your quarry fleet's maintenance on schedule alongside the rest of the plant.

Why Quarry Equipment Fails Differently
Plant equipment mostly fails from fatigue and wear inside a controlled environment. Quarry equipment fails from dust, vibration, impact loading, and operators pushing machines across uneven ground for ten hours straight. A haul truck's maintenance plan has to account for abuse that a kiln motor never sees, which is why generic PM schedules borrowed from the plant floor rarely work in the pit.
Where Each Machine Wears First
| Equipment |
Primary Wear Point |
PM Focus |
| Haul Trucks |
Tires, brakes, suspension cylinders under repeated load cycles |
Daily walk-around, tire pressure, brake wear checks |
| Wheel Loaders |
Bucket pins, hydraulic hoses, and articulation joints |
Grease points, hydraulic fluid analysis, pin wear tracking |
| Excavators |
Undercarriage tracks, bucket teeth, swing bearing |
Track tension checks, bucket tooth rotation schedule |
| Drill Rigs |
Drill string, compressor, and mast alignment |
Bit inspection, compressor oil checks, mast alignment audit |
Common Failures And The Fix That Prevents Them
Left Unchecked
Overheated wheel loader hydraulics from a clogged cooler
Premature tire failure from ignored pressure drift
Drill string fatigue cracks missed until a mid-hole break
Prevented By
Scheduled cooler cleaning tied to dust-season intervals
Shift-start tire pressure logging with automatic alerts
Routine drill string dye-penetrant or visual crack inspection
Give Your Quarry Fleet The Same Discipline As The Plant
Oxmaint schedules PM by engine hours or calendar days, whichever comes first, and pushes checklists straight to the operator's phone before shift start. Sign up for a free trial to load your fleet, or book a demo and we'll build your first quarry PM calendar.

How Oxmaint Supports Quarry Fleet Maintenance
Oxmaint tracks each machine by engine hours, not just calendar dates, so a haul truck running double shifts gets serviced sooner than one sitting idle. Checklists reach operators on mobile, and overdue PM tasks surface on the planner's dashboard before a failure does. Book a demo to see your fleet mapped into a working PM calendar.
Frequently Asked Questions
Q
Should quarry equipment be maintained on hours or calendar days?
Hours are usually the better trigger since duty cycles vary widely between machines. A calendar-only schedule can under-service a heavily used truck or over-service one that barely ran that month.
Q
What's the biggest driver of haul truck downtime?
Tires, brakes, and undercarriage components typically account for the majority of unplanned truck downtime, since they absorb the most direct impact from haul road conditions and load cycles.
Q
Can one PM program cover trucks, loaders, and drills together?
Yes, as long as each equipment class keeps its own checklist and interval logic. A shared CMMS platform can run all four fleets side by side without forcing them onto identical schedules.
Q
How often should drill rigs get a full inspection?
Most operations inspect the drill string, compressor, and mast alignment on a set hour interval, with a more thorough teardown inspection scheduled around each major blasting campaign.
Keep Your Quarry Fleet Running Before It Breaks
Oxmaint schedules PM for haul trucks, loaders, excavators, and drills by engine hours, pushes checklists to operators, and flags overdue work before it becomes downtime. Sign up for a free trial to load your fleet, or book a demo and we'll set up your first quarry maintenance calendar.
