Mining Fleet Inspection & Maintenance Software

It's 5:40 a.m. at the pit and the blast-hole drill that signed off clean yesterday won't build air — the rotary screw compressor is bleeding off through a chafed hose nobody flagged, and the pattern it was supposed to collar is now holding up the

A surface haul-truck checklist will not keep an underground truck safe. The decline, the shared ventilation and the dark change which items matter and how they fail. Below is a complete, copy-ready underground truck digital insp

Here's the part that catches mines off guard: you can run every inspection on schedule and still fail the audit. MSHA inspectors are spending more time on documentation than on equipment condition, because a bad guard gets fixed

A coal operation runs two kinds of machine that could not be more different to maintain — a dragline that strips overburden for forty years on structural and electrical cycles, and a mobile fleet of haul trucks, dozers and

A metal and ore operation doesn't run one kind of machine — it runs five or six, and every one of them fails in a different place. An ultra-class haul truck, a hydraulic shovel, a wheel loader, an underground LHD and the w

The interval wasn't a mystery. A haul truck crosses its service hours mid-shift during the busiest week of the quarter — and the reading that would have warned you was sitting in a logbook nobody checked in time. A haul tr

On the surface, a haul truck's engine hours sync to the PM schedule automatically through OEM telematics. Underground, that link usually doesn't exist — leaky feeder and Wi-Fi mesh networks run at a fraction of surface ban

One crew runs every scraper on the same "service it every 250 hours" rule — and the cutting edge is already three weeks overdue while the transmission got touched too early. A scraper doesn't wear on one clock. It wears on

Two dozers, same model, same hours on the clock, wildly different undercarriage left in the tank. One ran in sand, one in sharp rock — but nobody could tell you that from a log, because nobody was measuring. "Looks about t

The cab is supposed to be the one place on the pit that's clean air. Then a recirculation filter goes three months past due, a door seal cracks in the heat, and the operator's breathing the same dust as the ground outside &mdash

One oil service got pushed back a week on a 400-ton haul truck. Four months later, that truck sat five days waiting on a final drive. The skip didn't cause the failure — it just removed the checkpoint that would've caught

Most mine managers can tell you how many haul trucks, LHDs, and shovels are on the books. Far fewer can tell you, with real data, which of those machines actually earned their place on site last quarter. Right-sizing a mine fleet starts with utili

A wheel loader's articulation pin has been grinding for two shifts — logged once on a torn paper sheet that never left the cab. On the third shift, the joint lets go mid-swing with a loaded bucket, and the machine sits at

A dozer final drive doesn't fail all at once — it fails in stages, starting with a seal weep that most inspections wave past. Left alone, that weep runs 100–300 hours before the failure shows up, by which point a $500 seal repai

A LHD's load-haul-dump cycle is brutal on tires in a way almost nothing else underground is — short cycles, little cooling time, confined headings and a failure at the working face that's the hardest spot on the mine to recover

A jumbo drill doesn't need to be running to hurt someone — a boom or feed beam that isn't properly isolated during service has paralyzed a maintenance fitter on a routine hydraulic repair. Jumbo drill inspection software builds

A water truck that's still spraying isn't necessarily still suppressing dust — worn nozzle orifices enlarge over time, pushing more water out in a distorted pattern while actual dust knockdown quietly drops. Mining water t

The lube truck doesn't haul ore and doesn't move a cubic yard — but when its pump seizes at 6am, every PM round scheduled across the haul fleet that day stalls with it. The one truck whose entire job is keeping everything

A hydraulic mining shovel doesn't just move material — it sets the pace for every truck behind it. Hydraulic mining shovel inspection and maintenance software tracks structural fatigue, hydraulic health and meter-hour PM so the

An underground mine rarely runs one LHD — it runs a fleet of them across headings, and a tramming cycle is only as fast as the slowest bucket in the loop. LHD loader inspection and maintenance software tracks GET wear, cycle-kil

A fuel and lube truck doesn't dig, haul, or grade — but when it is down, nothing else on site can either. Mining fuel and lube truck inspection and maintenance software keeps the tank, pump, hose, and metering system tracked so

On a mining excavator, the teeth touching the rock do more damage to your budget than almost anything else on the machine — ground-engaging tools alone can run up to half of total operating cost in mining digging applications. M

A mining motor grader isn't just blading dirt — it's the machine standing between a smooth haul road and every truck on it running slower, burning more fuel, and eating tires faster. Mining motor grader inspection and maintenanc

You're accountable for the fleet's cost and availability — but the data to prove either one is scattered across a fuel-card portal, a maintenance binder, three supervisors' spreadsheets, and a telematics screen nobody chec

The first battery-electric LHD that rolls into your shop doesn't just drive differently — it retires half your inspection checklist and replaces it with a new one. No engine oil, no exhaust aftertreatment, no diesel PM int

The fuel invoice at the end of the month tells you what the fleet burned. It doesn't tell you which truck, which operator, or how many of those gallons went up the stack while a machine sat idling. Mining fuel cost tracking clos

When a rope shovel stops, it doesn't stop alone — every haul truck it was loading parks behind it, and a whole face goes quiet. That's why rope shovel inspection and maintenance software matters more here than on any other machi

In a truck-and-loader pit, the loader is the constraint — when it stops, the trucks queue and the dig stalls. Mining wheel loader inspection software catches the worn articulation pin, the cut tire, the cracked bucket edge on th

A haul truck doesn't fail on a calendar — it fails at 18,000 hours when the final drive you meant to rebuild at 16,000 lets go mid-shift. Mining equipment service tracking turns that $200,000 surprise into a planned rebuild in a

An ultra-class haul truck earns its keep on the loaded downhill haul — and that's exactly where a neglected frame crack, a tired suspension strut or an overdue service turns into a parked truck and tonnes that don't move. One haul truck down

When an MSHA inspector asks for a miner's training record, "we did the training" isn't the answer — the signed record is. Under MSHA Part 48, every training event a miner completes has to be documented and kept on file at the minesite, ready

A rebuilt engine doesn't care which haul truck it's bolted into — it carries its own hours, its own rebuild count and its own failure history from one machine to the next. On a mine running component-exchange maintenance, that's the unit tha

Roughly half of what a mining dozer costs you over its life is spent under the tracks — and on a pit's blasted, abrasive ground, that undercarriage wears faster than any spec sheet assumes. The dozer that's cutting benches and feeding the sh

A rotary drill rig is the machine that feeds the whole pit — when it's parked, the pattern doesn't get drilled, the shovels run out of face, and the haul fleet behind it idles. Yet the rig that can idle the most trucks is usually the one wit

A development jumbo is the machine the whole mine plan waits on — when it's down, the heading doesn't advance, and everything behind it slips. So when a mine goes looking for jumbo drill inspection and maintenance software, the real question

Any maintenance manager running a fleet of Cat haul trucks knows VIMS is sitting on every unit, logging everything — payload, engine load, oil temps, brake pressures, the abuse events an operator would never write up. The data's there. The problem

On the surface, a signal is a given. Underground, a drift bends, a borer rolls through, and the connection that was solid at the last crosscut is gone. Underground mining communication networks are what you build to fight that — leaky feeder, Wi-F

Underground, in a gassy heading, the ordinary tablet in a technician's hand is a problem — a battery fault or a stray spark in a flammable atmosphere is exactly the kind of ignition source a mine is built to eliminate. So when inspections go digit

Underground, every machine looks like the last one — same model, same mud, same low light, no serial number you can read without crawling under it. So when a loader needs a service, the first problem isn't the repair — it's being certain which exa

A digital twin is a living mirror of a physical asset — a virtual copy of a crusher, conveyor, or haul truck that updates as the real thing runs. In mining the promise is huge, but a mirror is only as clear as what it reflects: a digital twin is o

An anomaly is a question, not an answer. When a haul truck's vibration ticks above its normal band or an excavator's hydraulic pressure drifts, the sensor isn't telling you what's wrong — it's telling you where to look. Mining equipment anomaly de

It's Monday, 6:15 a.m. The crew board has eleven jobs on it. By seven, a haul truck is on the ramp with a blown hydraulic hose, your best crew is on it, and three planned PMs have quietly become "next week's problem." If that so

It's Friday at 4pm, the shutdown starts Monday at 6am, and the fitters are double-booked on Tuesday. That's the real test of mining shutdown planning: not whether you have a plan, but whether it survives crews, cranes and parts.

Day two of a crusher shutdown. The scope was frozen six weeks ago at 140 jobs. The planner is now looking at 171, and three of the new ones were added at the gate because “she's down anyway.” The liner kit for job 16

A drive pulley never warns you politely. The pulley lagging wears thin, the belt begins to slip against the drum, and in a wet or clay-heavy stream that slip quietly grinds away both the lagging and the belt's bottom cover until a sensor trips and

Your weightometer reads 4,180 tonnes for the shift and nobody questions it — until month-end reconciliation shows the plant shipped more than the belt scale said it moved. A belt scale that quietly drifts half a percent doesn't trip an alarm; it j

On a haul fleet, fuel is often the largest line after labour — and most of the waste hides across idling trucks, heavy-footed shifts and under-filled trays nobody adds up. Two identical trucks on the same road can burn very different amounts, and

The pressure to cut mine emissions lands hardest on the diesel fleet, and the first realistic lever isn't a battery haul truck — it's what goes in the tank today. Renewable diesel, HVO and biodiesel blends lower your carbon without replacing a mac

The crushers, mills and conveyors in your plant are the hungriest things on the mine — fixed plant burns the lion's share of a site's energy, and comminution alone can dominate the power bill. What most teams miss is that the number isn't fixed: a

Water never sleeps on a mine, and neither does the gear that moves it. Dewatering pumps run around the clock to keep levels dry, sensors watch the pit lake, and recycling plant returns dirty water to supply. When one asset fails unseen, a level fl

Mining component life planning is the difference between changing out a final drive on a planned shutdown and losing a haul truck mid-shift because the engine hit its hours and nobody was watching. Every major component — engine, transmission, fin

A rotable component pool is the set of major, repairable units — final drives, transmissions, hydraulic pumps, wheel motors — that a mine keeps circulating: pull a failed one, fit a ready one, rebuild the old one, and put it back in the pool for n

Component exchange vs repair is the call a mining maintenance manager makes with the clock already running. A final drive lets go on a haul truck mid-shift, and you've got two roads: pull it and bolt in a ready exchange unit so the truck is back o

Component rebuild specifications are what separate a final drive that runs another 9,000 hours from one that grenades at 1,500 — and on a mine site, the difference is rarely the parts. It's whether the rebuild was measured against a real spec, ver

The OEM vs third-party component rebuilders question shows up the moment a final drive or transmission lets go and three quotes land on your desk: the dealer's reman exchange, an independent rebuild for a lot less, and maybe a new unit on backorde

Mining equipment warranty claims get denied for a reason that has nothing to do with whether the failure was covered: the records aren't there. A final drive lets go at 4,200 hours, comfortably inside the window on paper, and the OEM still says no

A semi-mobile crusher exists to follow the pit — but the day you move one, it stops being a machine and becomes a project, with a hundred ways to lose a week and a few ways to hurt someone. Semi mobile crusher relocation is where structural, elect

At a rail load-out or port terminal, everything upstream exists to get product into a wagon or a hull on schedule. When a transfer chute blocks or a load-out conveyor trips, it isn't one machine down — it's a loaded train holding a path or a chart

Ask ten people on a mine site which asset matters most and you'll get ten answers — usually whatever broke last. Asset criticality ranking replaces that with a defensible order: score every machine by what happens if it fails, and let that score,

Most mining maintenance plans run on habit — this asset gets serviced every 250 hours because it always has. FMEA for mining equipment replaces habit with evidence: you list how each machine can fail, score how bad, how likely and how hard-to-catc

Fixing a defect and eliminating a defect are not the same job. A mining fleet can route every fault to a work order, close it clean, and still watch the same hydraulic failure or cracked bucket pin come back next month — because repair restores th

Every mining maintenance manager has that one haul truck — in the workshop every other week with the same final-drive complaint. Bad actor management is the reliability discipline that stops you chasing those chronic offenders forever: it finds th

A mine site induction is the gate before the gate — the day-one orientation every equipment operator has to pass before they're allowed near a haul truck or a loading face. New starter, seasoned operator from another site, or a contractor for a we

Confined space entry in mining is the one job where the space doesn't give you a second mistake. A bin, a tank, a chute, a baghouse hopper — step inside without testing the air, isolating the energy, and posting an attendant, and a routine clean-o

Mining maintenance reporting automation turns scattered inspection sheets, work orders, downtime logs and service histories into information a maintenance superintendent can use before the next shift. The objective is not another dashboard for its

Battery electric vehicles in underground mining change more than the powertrain. They affect ventilation assumptions, shift planning, charging access, maintenance skills and the way a mine proves that equipment is ready to work. For operators eval

Mining BEV charging infrastructure is not simply a question of buying enough chargers. At a surface mine, charging must fit haul cycles, shift changes, electrical supply, traffic movements and maintenance windows without undermining production. A

Mining BEV battery maintenance is more than checking a battery percentage before a shift. On an electric haul truck, loader or underground support vehicle, battery condition affects production availability, charging decisions, thermal safety and l

An electric haul truck can change the economics and operating rhythm of a surface mine, but adoption depends on far more than swapping a diesel engine for a battery. Haul-road grades, payload, cycle time, chargi

Copper mine equipment maintenance is a reliability problem across the entire material path: shovels load haul trucks, trucks feed crushers, and conveyors keep the concentrator supplied. A missed inspection or delayed repair at one bottleneck can d

Gold mine equipment maintenance is a different challenge depending on whether your crews work across an open pit, underground headings, or a processing plant. Haul trucks and loaders face heavy-duty cycles, while underground mobile equipment bring

Iron ore fleet management is a daily balancing act: haul trucks must keep material moving while maintenance teams protect brakes, tires, powertrains and the equipment that feeds the crusher. The strongest approach is not simply servicing more ofte

Phosphate mining equipment works through a demanding combination of abrasive material, wet handling, heavy loads and continuous production pressure. A worn dragline component, blocked slurry pump or failed conveyor can interrupt more than one mach

Mining contractor management comes down to one gate question asked hundreds of times a shift: is this worker cleared, or just standing here? A mine runs on contract crews — trades for a shutdown, specialists for a reline, labour hire for a surge,a

Strong mining maintenance planner skills turn equipment defects into jobs crews can execute safely, with the right parts, labor, access and downtime window. A scheduler then sequences those ready jobs around production commitments and crew capacit

A point of work risk assessment exists because the plan was written at a desk and the job happens at the machine — and the two are never quite the same. The method statement assumed dry ground; it rained overnight. It assumed the excavator was iso

In mining, stockpile management lives or dies on one thing nobody puts on the plan: whether the equipment shows up. You can build the smartest stockpile and rehandle strategy on the planet, but the day a loader is down or a dozer won't start, the

Dump point management is one of the most dynamic jobs in surface mine haulage, because the working edge changes all shift as material is placed, pushed, loaded out and worked by weather. Safe dumping takes more than a berm: it needs clear approach

Short interval control is the difference between finding out you missed the plan at end of shift and fixing the problem two hours in. Instead of one big reckoning at handover, the shift is broken into short intervals, actual production is checked

Payload management is the quiet lever that decides whether a haul truck earns its keep or wears out early. Load it light and you leave tonnes on the table every cycle; load it heavy and you trade short-term production for cracked frames, blown str

Mining production reconciliation is where the plan meets reality — and too often, nobody can fully explain the gap. You planned to move so many tonnes; you moved fewer; and when the question is why, the answer disappears into missing shift reports

Mine refuelling logistics is one of those costs that hides in plain sight — nobody books "refuelling" as downtime, but add up the trips to the fuel bay, the queues, the waiting on a fuel truck and the litres scribbled on a sheet, and it's real pro

A hot seat changeover is how a mine keeps a multi-million-dollar haul truck earning through shift change — the fresh operator climbs in as the outgoing one climbs out, right there in the pit, so the truck barely stops. Do it well and you claw back

Blast clearance procedures are the steps that make sure every person and machine is clear of the zone before a shot is fired — and that you can prove it afterward. On a mine, the blast is handled by licensed crews; the clearance is a coordination

A dust suppression program is easy to describe and hard to prove. On a mine site you've got water trucks on haul roads, sprays at the crusher, chemical on the ramps and speed limits everywhere — but when an auditor or MSHA inspector asks for the r

A loose busbar connection doesn't trip a breaker or throw a code — it just runs a little hotter every week until the day it arcs, drops a substation and takes a section of the mine down with it. You can't see that heat with your eyes, but an infra

A failing bearing, a hissing air leak and a valve that won't quite seal have one thing in common: they're all making noise you can't hear. Friction, turbulence and leakage all produce high-frequency sound above the range of the human ear — and tha

A big induction motor driving a conveyor or a crusher rarely tells you it's dying — until it stops the whole line. The remarkable thing is that it's been signalling the whole time, in the one place nobody was looking: its own current. Motor curren

Two shafts bolted together through a coupling look like one machine, but they almost never agree on their own. A fraction of a millimetre of offset or a sliver of angle between a motor and a pump — invisible to the eye — is enough to chew through

On a mine site, a bolt is never just a bolt. A haul-truck wheel nut, a shovel structural bolt, a mill flange — when one lets go it's not a repair, it's an incident report. The hard truth of mining bolting torque is that the number on the wrench is

An automatic lubrication system is supposed to be the one job you never have to think about — grease flows from a central pump through the lines to every bearing and pin, metered and on time, while the operator drives. The danger is exactly that:

Dealer vs in house maintenance is rarely a mine-wide yes-or-no decision. Routine preventive maintenance may fit an internal workshop, while specialized diagnostics, major component rebuilds or jobs requiring OEM tooling may favor dealer support. T

The most expensive number in a grinding mill isn't the liner — it's the reline date, and getting it wrong costs you either way. Mill liner wear is slow, uneven, and hidden inside a rotating drum, so sites either reline too early and waste li

A slurry pump isn't really one machine you maintain — it's a stack of wear parts you replace, on a clock the slurry sets. Slurry pump maintenance lives or dies on how well you manage that stack: the throatbush that goes first, the impeller t

A hydrocyclone has no moving parts, so it's easy to assume there's nothing to maintain — and that assumption quietly costs plants their recovery. Hydrocyclone wear happens invisibly inside the liner, apex, and vortex finder, and as those sur

The delivery driver dropping a load, the vendor rep checking a pump, the office contractor fixing a printer — none of them are miners, and every one needs MSHA hazard awareness training before they set foot past the gate. Site-specific hazar

The LHD is the hardest-worked machine in the mine. It loads, hauls, and dumps in a near-continuous cycle through heat, dust, water, and tight drifts — and when it stops, the ore stops with it, because everything from the production face flow

A longhole drill isn't a machine you baby — it's a production asset that runs shift after shift, joining rod after rod to drill deep blastholes, and every metre it doesn't drill is tonnes that don't get blasted. That relentless duty is exact

A cable bolter is three machines in one body: a drill that bores long deep holes, a cable system that feeds flexible steel tendons up into them, and a grout plant that mixes and pumps cement to bond it all — all done under freshly exposed, n

A raise boring machine does one job in two very different halves: it drills a slender pilot hole down between two levels, then swaps the bit for a reaming head and pulls it back up under enormous force to open the full raise. Both halves run on th

A shotcrete sprayer pumps abrasive concrete at pressure through a pump, a long line, and a nozzle — and injects a corrosive accelerator right at the tip. Every part in that path wears, clogs, or seizes if the machine isn't cleaned and checke

A stockpile can look completely solid and be seconds from collapse — the material a loader pulled from the bottom this morning has quietly steepened the face, and the next person who walks to the toe is standing in the collapse zone. Stockpi

Every mine runs on chemicals — fuels, solvents, lubricants, reagents, cleaning agents — and a miner has a legal right to know what they're exposed to. MSHA Part 47 HazCom is the rule that guarantees it, and it's built from five pieces

Noise is the mine hazard you can't see and can't undo — hearing loss is permanent, and it builds so gradually that a miner is often well down the road before anyone measures it. MSHA Part 62 noise rules exist to catch that early, and they tu

A miner can pick up the phone, describe a hazard at your mine, and trigger a mandatory MSHA inspection within hours — and you may never learn who called. That's a mine hazard complaint under Section 103(g), one of the strongest rights the Mi

A track-mounted jaw crusher doesn't belong cleanly to anyone. Your mobile fleet crew services it because it has tracks and a diesel engine. But inside that chassis sits a crushing chamber, exposed conveyors and moving parts that

Twice a year, an MSHA inspector walks onto your pit or quarry unannounced and asks for the training plan. Not certificates — the plan itself, and the records behind it. An MSHA Part 46 training plan is the one document eve

A hydraulic line lets go on an excavator mid-shift, the boom drops, and a groundman is pinned against the tracks. The first instinct on a production site is to free him, clear the machine, and get the pit moving again. That inst

A haul truck operator six hours into a night shift doesn't need a lecture on fatigue risk — they need a seat that isn't hammering their spine, air conditioning that actually works, and a windshield they can see through

A bulk diesel delivery ticket tells you how much fuel arrived on site. It doesn't tell you which haul truck burned it, how much idled away in a queue, or whether that litre-to-tonne conversion survives an auditor's questions.

The training happened. The new hire sat through all 24 hours, the instructor covered every topic, nobody cut a corner. Then an MSHA inspector asks to see the record, and the certificate is missing the instructor's name and n

The cut stops mid-face, the conveyor backs up, and the crew's first guess is always hydraulics — because it usually is. A continuous miner inspection that catches a weeping hose before it lets go is the difference between

An auditor pulls one line from the asset register: a bucket truck bought three years ago with a state grant. The question isn't whether the truck runs. It's whether anyone can prove it's still doing the job the grant paid for.

A miner shows up for a swing shift and gets turned around at the gate. Not for a safety violation on the job. His MSHA annual refresher training lapsed eleven days ago, and nobody in the office caught it until the badge scanner

Every mining maintenance team knows the difference between a good week and a bad one. A good week, you're working the jobs you planned — parts staged, machine scheduled out of the pit, techs on day rate. A bad week, a fina

When a haul truck goes down mid-shift, the number most operations write down is the repair invoice. That number is almost always the smallest part of what the failure actually cost. Mining equipment downtime cost is dominated by

A Caterpillar 950M loader shows 7,800 hours on the dash. Plug in a scan tool and the engine ECU reads 12,300. That 4,500-hour gap isn't a rounding error — it's a machine that's four filter changes and a hydraulic service o

Your system says twelve of that hydraulic seal are on the shelf. A fitter walks to the bin mid-repair and finds two. The machine waits, someone drives hours for an emergency part you thought you had, and the "spare" was a ghost

A hydraulic hose fails on one powered roof support out of two hundred. On any other operation that's a single-unit repair. On a longwall, the entire coal face stops — because the shearer, the supports, and the conveyor are

Your diamond drill rig is forty minutes down a bush track, the nearest parts store is a four-hour drive, and there's no cell signal to pull up last week's inspection. Then the mast winch starts making a noise. That scenario &mda

When a serious accident happens at a mine, the clock that matters most is 15 minutes long — that's how fast MSHA Part 50 reporting requires an operator to notify the agency once they know a reportable accident has occurred. It's the first of

A sand and gravel pit doesn't wear like a dry stone quarry. Abrasive slurry runs through dredge pumps, wash plants, and conveyors all day, grinding down impellers and screen media a dry crusher would never touch — and it's often a lean crew

Most quarries don't fail an MSHA equipment-inspection citation because a walkaround got skipped. They fail because they can't prove it happened, or because a defect got written on a pre-op report and the machine rolled anyway. That's the quiet gap

Send a Part 48 miner through a Part 46 class and the certificate will look almost right — but the training won't be valid, and your new hire may not be allowed to start work. That's the stakes on MSHA Part 46 vs Part 48: t

On a manned haul truck, your best condition-monitoring sensor was the operator. They heard the bearing whine, felt the vibration, spotted the leak at walkaround — and wrote it up. Take the operator out of the cab and that

You pull a hydraulic pump off a 100-tonne haul truck after 4,000 hours when it should have run 12,000, and the oil sample that comes back tells the story: dirt, not wear, killed it. Hydraulic contamination control in mining is the single biggest l

You know the moment: a haul truck throws a hydraulic fault code mid-shift, the pit goes quiet, and the maintenance phone starts ringing. By the time the unit is towed to the shop, you've lost a full production window and the parts you need aren't

You walk past a 793 sitting in the pit with a left-rear shredded down to the cords, and you already know what the shift report is going to say: rock cut, heat separation, or "operator didn't notice." That tire cost somewhere between $40,000 and $7

It is 05:40 at the pit gate, the shovel is waiting on its first truck of the shift, and your operator is standing next to a 400-ton machine with a flashlight and a paper card. A proper haul truck pre shift inspection on an ultra-class unit takes a

A mining water truck is usually the last machine on the inspection schedule and the first one blamed when the dust monitor spikes or a haul road turns to soup. Yet that "ancillary" unit carries two of the most expensive jobs on site: respirable du

You know the sound a 200-tonne haul truck makes when the frame lets go. Most maintenance managers have heard it once and never want to hear it again. Structural crack inspection on mining equipment is the discipline that keeps you out of that situ

Tyres are one of the biggest consumable costs on any mine site, yet most operations still track them by truck number instead of by serial and position. That single blind spot hides the wear patterns that would tell you which positions burn rubber

Your haul trucks are not a fleet problem in the usual sense — you might run forty machines, but each one costs more than a small trucking company's entire yard, and every hour one sits dead in the pit costs you real production. That is why mining

Your haul truck operator flags a brake issue on the pre-shift inspection at 6:40 a.m. By 9 a.m. that note is buried in a group chat, the truck is back on the bench, and nobody can say who owns the repair. That is the gap mining work order software

It's 6:10 a.m. at the pit and your 240-ton haul truck is down with a blown final drive - the same truck whose 500-hour service was due last week, except nobody knew, because the hour meter reading was still sitting in a text message from Tuesday.

It's 6:40 on a Tuesday morning, the night shift drilled 22 holes instead of the planned 40, and the day shift jumbo operator is standing at the face with a drifter that's hammering soft and a feed that won't hold its angle. Every hour that rig sit

It is 6:40 a.m. and the night-shift haul trucks are already stacking up at the pit because a washboard stretch on the main ramp is shaking loads loose and rattling operators half to death. The machine that fixes it is not the $5 million haul truck

A crusher inspection in mining is not a nice-to-have on the schedule - it is the one thing standing between a running plant and a dead one. When the primary crusher trips or a conveyor belt lets go, every truck and loader upstream stops earning, a

It is 6:40 a.m. at the pit face and your 250-tonne hydraulic mining shovel is sitting dead over a half-loaded truck because a main boom hose let go sometime in the last hour. The oil loss is bad; the lost production is worse, because when the face

You know the sound a dragline makes when something is wrong. Not the normal groan of steel under load, but the sharp ping of a broken wire strand snapping back against the boom, or the grinding hesitation in the swing gear that tells you the lubri

Blasthole drill inspection is the most neglected pre-shift check on most mine sites, yet the drill sits at the very head of the production chain: no holes means no blast, no blast means the shovels and trucks stand idle. You have probably seen it

You are 400 metres down a 1-in-7 decline, fully loaded, and the only thing between your operator and a runaway is a brake pack and a retarder that were last checked on a paper form three shifts ago. Underground haul truck inspection is not a box-t
