Stand at the edge of a big opencast pit and the first thing you notice is not the coal or the ore. It is the machines: haul trucks as tall as a house, shovels that can fill a truck in a few passes, and dozers working quietly at the edge of the dump. Every one of them costs a serious amount of money, and every one has to earn it back.
This guide gives you a working list of heavy mining machinery for opencast and underground mines, explains what each machine does, shows how to estimate its output and how to think about cost properly. One thing I will say straight away: I am not going to print a "price list". Mining equipment is sold on custom quotations, and the final price depends on configuration, options, taxes and duties, dealer support and service contracts. Any blog that lists exact 2026 prices for these machines is guessing. What you can do, and what this post helps with, is understand what drives the price and how to judge value.
Why you will not find reliable public prices
- Configuration matters. Engine, drive system (diesel-mechanical, diesel-electric, electric), body size, tyres, cab, automation readiness and fire suppression all change the price.
- Support packages are part of the deal. Parts supply, service contracts, operator training and warranties can be a large share of the cost.
- Taxes, duties and freight vary by country and by how the machine is imported or assembled.
- Market conditions change. Prices follow commodity cycles, steel costs and order books.
In general terms, the very largest machines (ultra-class trucks, big hydraulic shovels, large draglines) cost millions of dollars each, while underground loaders and trucks cost far less but are bought in larger numbers. For an actual number, ask authorised dealers for written quotations for your exact specification.

A few widely quoted specifications
- Caterpillar 797F: a 400 short ton (about 363 tonne) class rigid truck with an engine of roughly 4,000 hp.
- Komatsu 930E: a 320 short ton (about 290 tonne) class electric-drive truck.
- Liebherr R 9800: an ultra-class hydraulic excavator in the region of 800 tonnes operating weight, with a bucket of about 42 cubic metres in its largest configuration.
- Caterpillar D11: a large crawler dozer in the 850 hp class.
- Sandvik LH514 and LH517: underground loaders in the 14 and 17 tonne payload classes.
Specifications change with each generation and configuration, so use the manufacturer's current brochure for exact numbers.
How to estimate a truck's output (worked example)
Hourly production = Payload × Trips per hour × Efficiency
Let us take a truck with a 363 tonne payload working in an iron ore pit, with these assumed figures:
- Loading and spotting plus dumping = 4 minutes
- Loaded haul = 8 minutes
- Empty return = 6 minutes
- Total cycle time = 18 minutes
- Efficiency (availability and utilisation combined) = 0.85
Trips per hour = 60 ÷ 18 = 3.33
Output = 363 × 3.33 × 0.85 ≈ 1,028 tonnes per hour
Over a 16-hour working day that is roughly 16,450 tonnes per truck. In practice the figure depends on haul distance, gradient, queuing, weather and operator skill, so replace the assumed numbers with measured ones from your own mine. For more worked calculations, read our guide to mining production calculation.
Matching the loading tool to the truck
Machines are only productive when they are matched. Suppose an ultra-class excavator has a 42 m³ bucket, a fill factor of 0.9 and the material has a loose density of 1.8 t/m³ (all assumed):
- Payload per pass = 42 × 0.9 × 1.8 ≈ 68 tonnes
- Passes to load a 363 tonne truck = 363 ÷ 68 ≈ 5.3, so about 5 to 6 passes
As a rule of thumb, mining companies aim for a truck to be filled in a small whole number of passes. Too few passes and the bucket is oversized for the truck. Too many and the loading time drags down the whole fleet.
Think in cost per tonne, not purchase price
The purchase price is only the start. A better way to compare machines is the all-in cost per hour divided by the tonnes moved per hour:
Cost per tonne = (Owning cost per hour + Operating cost per hour) ÷ Tonnes per hour
- Owning cost: depreciation, interest, insurance and taxes
- Operating cost: fuel or power, tyres, maintenance and repairs, lubricants, operator and supervision, ground-engaging tools
Illustration with assumed numbers only: if the all-in cost of a machine were $400 per hour and it moved 800 tonnes per hour, the cost would be $0.50 per tonne. A cheaper machine that moves fewer tonnes per hour, or breaks down more often, can easily cost more per tonne than an expensive one. That is why careful buyers compare total cost of ownership over the life of the machine.
Buying checklist
- Define the job first: material, density, digging conditions, haul distance, gradients, bench height and target output.
- Match the fleet, not just single machines: loader to truck, truck to crusher, dozers and graders to support the pit.
- Check local dealer support: parts availability, trained technicians and response time matter more at remote sites.
- Look at fuel and power efficiency and the options for electrification, trolley assist or hybrid systems if they suit your mine.
- Ask about safety features: visibility aids, proximity detection, fire suppression, ROPS/FOPS and operator comfort.
- Verify statutory approvals. In India, check what DGMS and other regulations require for the machine and its use in your type of mine.
- Plan operator training and maintenance before the machine arrives.
- Get written quotes from more than one supplier, with clear scope, warranty and support terms.
Common mistakes when buying heavy mining machinery
- Choosing on lowest purchase price and ignoring lifetime cost
- Ignoring site conditions such as haul road design, rock hardness and climate
- Buying machines that do not match each other in size
- Skipping operator training, which directly affects fuel, tyres and breakdowns
- Underestimating tyre costs for large trucks, which can be a major operating expense
- Overlooking emission rules and future power options
Safety and performance tips
- Keep haul roads well graded, properly drained and watered. Road condition affects both safety and cycle time.
- Follow the manufacturer's maintenance schedule and use condition monitoring to catch faults early.
- Manage tyres actively, with proper pressures, inspection and rotation.
- Train operators with simulators and on-the-job coaching, and use only authorised operators.
- Maintain berms, signage, lighting and traffic rules, especially around dumps and loading areas.
- Where available, use fleet management and automation systems, and measure the results on your own site.
- Follow ISO 45001-style safety management and the applicable legal requirements, including DGMS rules in India.
Buying used equipment
Used machines can be good value, but only after a thorough inspection. Check operating hours, service and rebuild history, hours on major components (engine, transmission, final drives, frame), structural cracks, hydraulic condition and parts availability. Get an independent inspection if the machine is large and expensive, and factor in the cost of any rebuilds that will be due soon. Do not rely on a rule of thumb about "how much cheaper" a used machine should be.
Frequently asked questions
What is the most expensive piece of mining machinery?
Very large draglines and the biggest rope or hydraulic shovels are among the costliest machines in mining, each running into many millions of dollars. Exact prices are not published, so ask for quotations.
How much does a 400-ton haul truck cost?
Machines in this class cost millions of dollars, but the final price depends on configuration, options, taxes and support. Contact an authorised dealer for a real quotation.
How do I compare two machines fairly?
Compare cost per tonne over the machine's life, using realistic output, fuel, tyre and maintenance figures for your site, not just the purchase price.
Are used machines a good investment?
They can be, if inspected carefully and if the remaining life of the major components justifies the price. Always budget for rebuilds.
Which manufacturer is best?
There is no universal answer. Each major manufacturer has strong products. For you, local support, fleet compatibility and the total cost of ownership usually decide.
Final thoughts
A heavy mining machine is not just a purchase, it is a long-term commitment to a particular way of working. Understand the job, match the fleet, compare cost per tonne and plan for support and safety, and the choice of brand becomes a lot easier.
