Heavy equipment is any large, powered machine built to dig, move, lift, haul, drill or process material. Most guides stop at the construction site. This one also covers the machines that work in mines, quarries and processing plants, because many operations run both kinds.
The easiest way to understand the types of heavy equipment is by the job each machine does. Below are six groups, the main machines in each, and what to think about when you choose and maintain them.
Heavy Equipment Classification at a Glance
| Category | Main machines | What they do |
|---|---|---|
| Earthmoving | Excavators, bulldozers, wheel loaders, backhoes, graders, scrapers | Dig, push, load and shape ground |
| Hauling and material handling | Haul trucks, articulated dump trucks, conveyors, telehandlers, cranes | Move material and lift loads |
| Drilling and rock breaking | Surface drill rigs, blasthole drills, hydraulic breakers | Drill blast holes and break oversize rock |
| Crushing and screening | Jaw, cone and impact crushers, screens, mobile plants | Reduce and sort rock into products |
| Underground mining | Face drilling jumbos, LHDs, underground trucks, bolters | Develop and produce below ground |
| Road building and compaction | Rollers, pavers, cold planers | Build and finish road surfaces |
1. Earthmoving Equipment
Earthmoving machines are the most familiar heavy equipment names, and they appear on almost every site.
- Excavators. A boom, stick and bucket on a rotating house, mounted on tracks or wheels. They dig, trench, load trucks and, with a hydraulic breaker, break rock. See our guide on how to choose a hydraulic breaker for your excavator.
- Bulldozers. Tracked tractors with a front blade for pushing material, plus a rear ripper for hard ground.
- Wheel loaders. Load trucks, feed crushers and manage stockpiles. In quarries they are often the busiest machine on site.
- Backhoe loaders. A loader at the front and a small digging arm at the back. Ideal for utilities and smaller jobs.
- Skid steers and compact track loaders. Small, agile machines for tight spaces and cleanup.
- Motor graders. Use a long blade to level ground and maintain haul roads.
- Scrapers. Cut, carry and spread soil in one cycle on large earthworks.
These machines share hydraulic systems that work hard every shift. Learn the warning signs of hydraulic pump failure before a small leak becomes a long stoppage.
2. Hauling and Material Handling Equipment
- Rigid haul trucks. Large off-highway trucks for open-pit mines and big quarries, built for heavy loads on maintained haul roads.
- Articulated dump trucks (ADTs). Hinged in the middle for traction on soft or steep ground.
- Conveyors. Move material continuously between crushers, screens and stockpiles, often cheaper per ton than trucks over fixed routes.
- Telehandlers and cranes. Lift parts, liners and components during maintenance and construction.
3. Drilling and Rock Breaking Equipment
In hard rock, nothing moves until it is drilled and blasted.
- Surface drill rigs. Top hammer rigs drill smaller, fast holes in quarries and construction. Down-the-hole (DTH) rigs drill larger, straighter holes in hard rock. Epiroc rigs are a common choice for both.
- Blasthole drills. Large rotary or DTH rigs for production blasting in open-pit mines.
- Hydraulic breakers and rock breakers. Break oversize boulders at the face or at the crusher grizzly, so the plant keeps flowing.
Drill rigs need disciplined care to stay productive. Our Epiroc drill rig maintenance guide covers the checks that protect uptime.
4. Crushing and Screening Equipment
Crushing and screening equipment turns blasted rock into sellable aggregate or ore feed.
- Jaw crushers handle primary crushing of large feed.
- Cone crushers produce finer, more cubical secondary and tertiary products. Compare them in jaw crusher vs cone crusher.
- Impact crushers shatter softer rock and recycled concrete with high-speed blow bars.
- Vibrating screens split crushed material into sizes.
- Mobile crushing and screening plants, such as the Metso Lokotrack line, move between sites on tracks.
These machines consume wear parts fast. Know how to identify and replace worn crusher wear parts and how to pick the right screening media.
5. Underground Mining Equipment
Underground mines use compact, purpose-built machines that fit tunnels and meet ventilation rules.
- Face drilling jumbos drill the tunnel face for blasting.
- Load-haul-dump machines (LHDs), often called scooptrams, load and carry ore from the face.
- Underground trucks haul ore and waste to the surface or a shaft.
- Rock bolters and scalers secure the roof and remove loose rock to keep crews safe.
6. Road Building and Compaction Equipment
Rollers compact soil and asphalt, pavers lay asphalt, and cold planers mill old surfaces. Mines and quarries also use rollers and graders to maintain haul roads, which cuts tire wear and fuel use.
Construction vs Mining Equipment: What’s the Difference?
Many machine types appear in both industries, but mining versions work much harder. They are usually larger, run around the clock, and face abrasive rock that wears buckets, liners and undercarriage faster. That means mining fleets need a stronger parts plan. Read our guide to building a parts inventory strategy that protects uptime.
How to Choose the Right Type of Heavy Equipment
- Material. Rock hardness and abrasiveness decide the drill, crusher and wear parts you need.
- Volume. Required tons per hour sets machine size.
- Haul distance and ground. Short, soft hauls suit ADTs; long, fixed routes may suit conveyors.
- Site access. Tight or underground sites need compact machines.
- Parts and service support. A machine is only as productive as its supply chain. Check how fast parts reach your site, especially in remote regions. See the real cost of lead time delays.
- How you will pay. Compare options in heavy equipment financing vs leasing.
Keeping a Mixed Fleet Running
Most operations run several brands and machine types. Sourcing parts from one supplier who knows them all saves time and mistakes. MMPAS, an authorized Epiroc and Metso dealer in Miami since 2001, supplies machinery for sale and lease, OEM and aftermarket spare and wear parts, and service support across the US, the Caribbean and South America.

Frequently Asked Questions
What are the main types of heavy equipment?
The main types are earthmoving, hauling and material handling, drilling and rock breaking, crushing and screening, underground mining, and road building and compaction equipment.
How is heavy equipment classified?
Heavy equipment is usually classified by the job it does, such as earthmoving or hauling. It can also be grouped by industry, size, or by whether it runs on tracks or wheels.
What is the most common piece of heavy equipment?
The excavator is the most widely used. It digs, loads, trenches and, with attachments like breakers, handles demolition and rock work.
What heavy equipment is used in mining?
Surface mines use drill rigs, excavators, haul trucks, wheel loaders, dozers and crushers. Underground mines use jumbos, LHDs, underground trucks and rock bolters.
What is the difference between an excavator and a backhoe?
An excavator has a cab that rotates 360 degrees and is built for heavy digging. A backhoe loader has a front loader and a smaller rear arm, making it better for lighter, mixed jobs.
What is earthmoving equipment?
Earthmoving equipment digs, pushes, loads and shapes soil and rock. Excavators, bulldozers, wheel loaders, graders and scrapers are the main examples.
