Hey there, let’s cut to the chase—if you’re in mining, you know the biggest piece of equipment on site that makes or busts your productivity is the mining truck. And if you’re here asking about the different sizes, chances are you’re either upgrading your fleet, planning a new mine, or just tired of guessing which truck size works for your operation. I’m gonna break this down like I would over a coffee with my lead mine operator buddy—no stuffy engineering jargon, just real talk, plus the stuff I wish someone had told me when I first started selling these bad boys back in 12 years ago. Mining Truck
First off, let’s set the baseline: mining trucks aren’t your average construction dump truck. These things are built for hauling massive, rocky loads up steep, unpaved mine roads, 24/7, in some of the harshest environments on the planet. Size isn’t just a “bigger is better” flex—get this wrong, and you’re wasting fuel, wearing out brakes early, or even causing safety hazards if the truck can’t fit through your mine’s tunnel portals or around your loading equipment.
Let’s start with the smallest end of the spectrum. No, I’m not talking about those tiny dump trucks you see on a residential construction site—those are for landscaping, not mining. The smallest mining trucks you’ll actually see on a real mine site are what we call the “Entry-Level Mini-Miners” (let’s just go with mini for short). These bad boys have a payload capacity of 30 to 60 tons. Wait, 60 tons? That’s still huge compared to anything you’d rent for a home project. But for mining, these are for small to medium operations—think open-pit mines that are just getting off the ground, or maybe small underground mines (though some underground mines run even smaller, but we’ll stick to surface first). Why pick mini? If you’re not moving 100,000 tons a day yet, going too big means you’ll be underutilizing the truck—wasting fuel on a truck that could haul twice as much, but you only need half. These are also way easier to maneuver around tight loading zones, like if your mine uses smaller excavators to load. The typical manufacturer here? Caterpillar has their 775G, which hits around 55 tons, and Komatsu’s HD465-8 is right in that 60-ton range. I’ve sold these to a gold mine in northern Ontario a few years back when they first opened up, and they told me it was the perfect size—didn’t have to rework their access roads, and their loader operator didn’t get overwhelmed with a too-big truck. But fair warning: don’t even think about using these for a mine that’s pulling 200k tons a day—you’d need 4 of these to do the work of one mid-size, and that adds up on operator salaries, maintenance, and fuel.
Next up is the workhorse of most modern mines: the Mid-Size Mining Truck. Payload here is 70 to 150 tons. This is the sweet spot for the majority of open-pit mines, from coal to copper to even iron ore that’s not at the massive scale. Why is this the sweet spot? It balances capacity with maneuverability. You can fit these on most standard mine access roads (we’re talking 30-foot wide roads, which are super common), and they pair perfectly with mid-size excavators—usually 30 to 50 ton excavators that can load a mid-size truck in 4 to 5 passes. No wasting time waiting for a loader to finish, no overloading the truck. I’ve had more clients go with mid-size than any other category, and the feedback is consistent: “They get the job done without the hassle of giant trucks that need a whole crew to operate.” Caterpillar’s 793F is a staple here—150 tons, been around for ages, super reliable. Komatsu’s HD785-8 is right there too, same payload. I also love the Liebherr T264, which is a bit newer, has better fuel efficiency than older mid-sizes—important because fuel is one of the biggest operating costs for mines. One client in Wyoming runs 12 of these mid-size trucks for their coal mine, and they told me last year they cut their fuel costs by 12% compared to their old 150-ton models because of the better engine tech, plus they fit through their road bridges without needing any upgrades to weight limits. That’s the thing I always emphasize with mid-size: don’t overlook the little stuff like road weight limits. If your mine is on old access roads built for smaller trucks, mid-size is way less risky than jumping straight to large.
Now we get to the big boys—Large Mining Trucks, the ones that make you go “holy crap” when you see them on site. Payload here is 180 to 300 tons. These are for mines that are moving massive volumes—like 300,000 to 500,000 tons a day, usually large copper or iron ore mines. These trucks are built for one thing: maximum haulage per trip. Why? Because when you’re moving millions of tons of material a month, every extra ton per load adds up. A single large mining truck can pull twice as much as a mid-size, so you need half as many trucks on site, which means fewer operators, less maintenance on extra trucks, less downtime. But here’s the catch: these things are not for small operations. You need access roads built specifically for heavy loads—some mines have to widen roads or reinforce bridges just to get these in, and they need giant excavators (60 to 90 ton models) to load them, which means your entire fleet of loading equipment has to be upgraded too. I’ve seen mines make the mistake of going for large trucks too early—one gold mine in Nevada tried it 5 years ago, spent a fortune on two 220-ton trucks, only to realize their excavator was too small to load them fast, so the trucks sat half the day. They ended up selling them after a year and going back to mid-size. Manufacturers here are Caterpillar with the 797F (wait, that’s even bigger, hold on), no—wait, 793 is mid, 797 is large, yes, 360 tons, but the large category starts at 180. Komatsu’s 785 is mid, their 980 is 250 tons, that’s large. Liebherr also has T282, which is 220 tons. The big thing here is ground pressure—these trucks have so much weight, you can’t use them on soft ground without reinforcing it, which adds to your site prep cost. So if you’re planning a new mine, factor that in upfront, not after you buy the trucks.
Then we have the absolute behemoths—Ultra-Class Mining Trucks, the ones that are basically buildings on wheels. Payload here is 350 tons and up, with the biggest ones hitting 400 tons. Let’s be real, these are not for the average mine. You’ll only see these at the largest open-pit mines in the world—like BHP’s iron ore mines in Western Australia, or big copper mines in Chile. These are for mines moving over 500,000 tons a day, where every single trip counts. The upside here is unbeatable haulage per unit: one ultra-class truck can do the work of two large or three mid-size trucks, so your fleet size is tiny compared to the volume you’re moving. But the downside? They’re ridiculous to operate. They need dedicated, wide access roads that can handle their size and weight (some roads are 60 feet wide for these), they need massive maintenance bays—you can’t work on an ultra-class truck in a standard garage—and they take special training for operators. I’ve only sold a handful of these in my career, mostly to that BHP mine in Australia, and the maintenance manager there told me they have a team of 12 full-time mechanics just for their two ultra-class trucks. If your mine isn’t moving millions of tons a month, don’t even look at these. You’ll be throwing money away on excess capacity and upkeep. The big names here: Caterpillar 797F, which is 360 tons, Komatsu 980E-SE at 400 tons, Liebherr T284 at 363 tons. These things cost $5 to $7 million each, by the way—way more than mid-size trucks which are around $1 to $2 million. So you have to be sure your operation can justify that price tag.
Wait, hold on—did I miss underground mining trucks? Yeah, because most people talking about mining trucks mean surface, but underground is a whole different ballgame. Underground mining can’t have giant trucks because of tunnel size. So underground mining trucks are way smaller, payload from 10 to 30 tons. These are called articulated trucks (or “ articulated dump trucks, ADTs” if you want the industry term), they can turn tight corners in narrow tunnels, and they’re built to handle uneven, slippery underground ground. If you’re running an underground mine, you’re not going to see any of the surface sizes I talked about earlier—stick to these tiny, maneuverable ones. I’ve sold these to diamond mines in South Africa, and they’re a lifesaver down there, way better than trying to squeeze a mid-size truck through a tunnel that’s only 12 feet wide.
Now, let’s cut through the bullshit and talk about what actually matters when picking size, because it’s not just payload. Here’s the stuff I wish every mine operator asked before buying: first, site layout. What’s the width of your access roads? What’s the weight limit on your bridges? How tight are your loading zones? A mini or mid-size might fit, a large or ultra might not. Second, loading equipment size. Can your excavator load the truck in under 5 passes? If it takes 10 passes, you’re wasting time and money. Third, daily production target. If you need to move 100k tons a day, a mini isn’t going to cut it. If you need 1 million tons a day, don’t waste money on mid-size. Fourth, operating costs. Bigger truck doesn’t mean cheaper per ton hauled—you have to factor in fuel, maintenance, operator pay, road upgrades, even tire costs (tires for an ultra-class truck are $50k each, ouch).
I’ve seen so many mines get this wrong, and it’s not their fault—there’s so much conflicting info online, and sales guys will tell you any size to make a commission. That’s why I always push clients to do a site audit first. We’ll send a team to your mine (or planned mine site) to measure roads, check bridge limits, test your loader’s loading speed, and crunch the numbers on daily production. No pressure, no hard sell—just real data on what size will work best for you.
At the end of the day, there’s no “best” size of mining truck—only the right size for your specific operation. If you’re a small mine just starting out, mini is perfect. If you’re mid-sized, mid-size is your workhorse. If you’re a giant operation moving massive volumes, ultra-class is the way to go. But for everyone, the worst mistake is overbuying or underbuying because you didn’t do your homework.
