Cat D11 vs Cat D8: which mining dozer fits the scale of your pit?
The Cat D11 is far larger than the Cat D8, with 850 HP against 363 HP, an operating weight of 104,236 kg against 39,000 kg, and a bigger blade at 34.4 m³ against 10.3 m³. Its fuel tank also holds more, at 1,800 litres against 624 litres, so it needs refuelling less often on long shifts. The D8 is the smaller, lighter machine of the two, easier to move around a site, and it runs a simpler engine with fewer parts to service.
Both are mining dozers in our dozer range. The D11 needs specialised transport and dedicated rebuild facilities to match its scale, so it suits only the largest opencast coal and metal mining operations, where one dozer can replace several smaller machines on bulk push. The D8 gives a mid-size mining or quarry fleet a step up from construction-class dozers, without that scale commitment. Read the bulldozer guide to compare mining dozer classes before you decide.
Cat D11
Pros:
Far more engine power at 850 HP against 363 HP on the D8
Much bigger operating weight at 104,236 kg, giving more pushing force per machine
Bigger blade at 34.4 m³ against 10.3 m³, moving far more material per pass
Larger 1,800-litre fuel tank supports longer shifts between refuelling
Wider track shoe option, standard at 710 mm with 810 mm or 915 mm optional for extra flotation
Suspension-type undercarriage cuts shock loads by up to half, and remote dozing tech lets one driver run up to four machines
Cons:
Needs specialised transport and dedicated rebuild facilities because of its size, so it suits only the largest mining fleets
Cannot easily scale down if a mine's production plan shrinks, unlike smaller dozers that redeploy more easily
More complex electronic and automated blade and ripper systems than the D8's simpler control layout, meaning more to learn and maintain
No pin-puller option mentioned for ripper tip changes, unlike the D8
Cat D8
Pros:
Simpler engine design, a single ECM with no exhaust gas recirculation, giving fewer failure points and simpler diagnostics than the D11
Fully automatic 4-speed transmission keeps fuel burn steady across drivers of different skill levels
Ripper offers a pin-puller option for quicker tip changes
Smaller and lighter machine, easier to move and reposition around a site than the D11
Standard automatic climate control cabin and telematics link for machine monitoring
Cons:
Far smaller blade at 10.3 m³ against 34.4 m³ on the D11, moving much less material per pass
Less engine power at 363 HP against 850 HP on the D11
Lighter at 39,000 kg against 104,236 kg, so more machines are needed to match the D11's output
Smaller 624-litre fuel tank needs more frequent refuelling than the D11's 1,800 litres on long shifts
Pros:
Cons:
Closing Recommendation
The Cat D11 suits the largest opencast coal and metal mining operations, where its engine power, operating weight and blade capacity let one machine handle bulk dozing that would otherwise take several smaller dozers, even though it needs specialised transport and dedicated rebuild facilities to match. The Cat D8 suits mid-size mining and quarry fleets that need more push than construction-class equipment but do not need the D11's scale, with a simpler engine that is easier to service and a machine that is easier to move around a site. So match the machine to your work: Cat D11 for large-scale bulk dozing in big opencast pits, Cat D8 for mid-size mining and quarry operations.
Cat D11 Vs Cat D8 Dozer Price, Technical Specifications & Features
The Cat D11 is a 104.2-tonne mining crawler dozer with an 850 HP engine and 34.4 m³ blade capacity. It is the largest of Cat's three mining dozers listed here. Its size is aimed at large coal and metal mining operations where smaller machines cannot maintain the required output. Ripper configurations include specialty leach-pad and 5-shank coal options. Optional counterweights add force where required, while a rear drawbar with counterweight supports towing and stability on steep grades. Ground clearance reaches 798 mm, helping the machine work around rough pit surfaces. Its 1,800-litre fuel tank supports long working shifts with less frequent refuelling. Large-fleet buyers can consider this dozer machine for high-volume overburden and coal-handling work. The blade capacity allows substantial material movement in each pass. Its operating weight also provides the pushing force required for large mining cuts. General construction is not the intended application at this scale. Buyers considering the D11 should match its capacity to the expected mining volume and ground conditions. For operations requiring the highest capacity within this Cat range, the D11 provides a dedicated mining crawler dozer solution.
The Cat D8 is a 39-tonne mining crawler dozer with a 363 HP engine. It provides an entry point into Cat's larger mining machines and sits below the D10 and D11. Blade capacity reaches 10.3 m³, giving it substantial material-moving ability for mine benches and haul roads. Ground bearing pressure of 88.5 kPa suits firm mining ground. Multi-shank and single-shank ripper configurations are available, with the single-shank option using CapSure hammerless tips. A pin-puller option is available for tip changes. These features are useful where ripping forms a regular part of the work cycle. A 624-litre fuel tank supports full-shift operation. The D8 suits quarry and opencast operations where construction-class dozers no longer provide enough capacity. A quarry operator scaling up an aggregate fleet can consider this dozer machine before moving into the larger D10. Its blade capacity supports larger cuts without the operating weight of Cat's biggest mining machines. Buyers can also choose the ripper configuration according to ground conditions. The D8 therefore provides a practical mining crawler dozer for operators needing more pushing and ripping capacity than construction equipment can provide.

The Cat D11 has far more engine power. It is rated at 850 HP (634 kW), against 363 HP (271 kW) on the Cat D8. This is more than double the output, which is why the D11 is used for the largest bulk-dozing work in open pits.
Ans.
The Cat D11 has the bigger blade. Its blade capacity is 34.4 m³, against 10.3 m³ on the Cat D8. That means the D11 moves far more material in a single pass, which suits high-volume overburden and coal-handling work where output per pass matters most.
Ans.
The Cat D11 holds more fuel. Its tank capacity is 1,800 litres, against 624 litres on the Cat D8. This lets the D11 run longer between refuelling stops, which matters on large sites where refuelling takes the machine off the job.
Ans.
The Cat D8 has the simpler engine to service. It uses a single ECM with no exhaust gas recirculation system, giving fewer parts that can fail and simpler diagnostics than the D11's more complex electronic and automated systems. The D11 trades that simplicity for much higher output.
Ans.
The Cat D8 fits a mid-size fleet better. It is smaller and lighter than the D11, so it is easier to move around a site and does not need the specialised transport or dedicated rebuild facilities that the D11's scale calls for. The D11 is built for the largest pits only.
