Cat D11 vs Komatsu D155A-6: which mining dozer fits your operation?
The Cat D11 is by far the bigger machine, rated at 850 HP against the Komatsu D155A-6's 360 HP, with a 34.4 m³ blade against 9.4 m³ and an operating weight of about 104,236 kg against 41,700 kg. It is built for the biggest opencast mining operations, where one machine needs to move as much material as several smaller dozers combined. The D155A-6 is a mid-size mining dozer with an automatic transmission and a lockup torque converter, which cuts driveline slip on long pushes to save fuel, plus selectable power and economy working modes.
Both are mining dozers in our dozer range. The D11 fits large-fleet buyers running sustained bulk dozing and heavy ripping at the biggest pits, but it also demands ultra-class transport, rebuild facilities and capital, and cannot scale down if the work volume drops. The D155A-6 fits mid-size mining and quarry contractors moving up from construction-class equipment, where fuel use per bank cubic metre is measured closely. New to dozers? Read the bulldozer guide first.
Cat D11
Pros:
Far more engine power at 850 HP against 360 HP on the Komatsu D155A-6
Much bigger blade at 34.4 m³, moving far more material in each pass
Larger 1,800-litre fuel tank against 625 litres, for longer runtime between refuels
Wider track shoes, 710 mm standard and up to 915 mm optional, against 560 mm
Suspension-type undercarriage that Caterpillar states cuts shock loads to the frame and components by up to half
Automation options such as Terrain 3D blade control and Command for Dozing let one driver run multiple machines
Cons:
Far heavier at about 104,236 kg against 41,700 kg, needing bigger transport and site infrastructure
Demands ultra-class capital, transport and rebuild support, and cannot be scaled down if the work volume drops
No lockup torque converter or selectable power/economy modes like the D155A-6's transmission offers for fuel saving on long pushes
Komatsu D155A-6
Pros:
Automatic transmission with a lockup torque converter, cutting driveline slip on long pushes to save fuel, plus selectable power and economy modes
Far lighter at about 41,700 kg against 104,236 kg, fitting mid-size mining and quarry operations without ultra-class transport needs
Two ripper configurations, a 3-shank ripper reaching 900 mm and a giant single-shank reaching 1,370 mm, to match different ground
KOMTRAX telematics built in, with a 4-stage troubleshooting code system for fleet monitoring
An extra transmission gear, 4F/4R against the D11's 3F/3R
Cons:
Far less engine power at 360 HP against 850 HP on the Cat D11
Much smaller blade at 9.4 m³ against the D11's 34.4 m³, moving less material per pass
Smaller 625-litre fuel tank against 1,800 litres, needing more frequent refuelling on long shifts
Narrower track shoes at 560 mm against the D11's 710 mm standard width
Pros:
Cons:
Closing Recommendation
The Cat D11 brings far more engine power, a much bigger blade and a larger fuel tank, built to concentrate production at the largest opencast mining sites, though it demands ultra-class transport, rebuild support and capital that cannot scale down if the work volume changes. The Komatsu D155A-6 is a lighter, mid-size mining dozer whose lockup torque converter and power/economy modes help it use fuel efficiently over sustained pushing hours, fitting fleets that measure fuel per bank cubic metre closely. So match the machine to your work: Cat D11 for the largest opencast mining operations needing maximum push per pass, Komatsu D155A-6 for mid-size mining and quarry operations that value fuel efficiency and a lighter capital commitment.
Cat D11 Vs Komatsu D155A-6 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 Komatsu D155A-6 is a 41.7-tonne mining crawler dozer powered by a 360 HP engine. Its 9.4 m³ blade provides substantial material-moving capacity, while two ripper configurations give operators different approaches to breaking. The 3-shank multi-shank ripper reaches 900 mm, whereas the giant single-shank reaches 1,370 mm for deeper work. SIGMADOZER, Semi-U and Full-U blade configurations are available for different applications. Ground bearing pressure is 115.8 kPa, with 500 mm of ground clearance for rough mining surfaces. A 625-litre fuel tank supports full-shift operation. The D155A-6 is the smallest of Komatsu's listed mining crawler dozers and sits below the D275A-5R, D375A-6 and D475A-5E0. Quarry and opencast operations are suitable applications. Pricing is available on request from mining dozer dealers. A mining contractor moving beyond construction-class equipment can consider this dozer machine when greater pushing and ripping capacity becomes necessary. The two ripper configurations allow buyers to match the setup to the ground. Its operating weight keeps it below the larger Komatsu mining machines. For operators entering mining-class dozer ownership, the D155A-6 provides a practical starting point before moving into higher-capacity equipment.

Questions buyers ask about the Cat D11 vs Komatsu D155A-6
Ans.
The Cat D11 is far more powerful. It is rated at 850 HP against the D155A-6's 360 HP, more than double the output, with a piston displacement of 32.1 litres against 15.24 litres. This extra power is what lets it push a much bigger blade through large-scale mining cuts.
Ans.
The Cat D11 moves far more material per pass. Its standard U-blade holds 34.4 m³ against the D155A-6's 9.4 m³ semi-U blade, and Caterpillar also offers Reclamation and Coal U-blade options up to 75 m³ for higher-volume mining work. The D155A-6's smaller blade suits a smaller-scale cut.
Ans.
The Komatsu D155A-6 is the easier machine to bring in. It weighs about 41,700 kg against the D11's roughly 104,236 kg, so it does not demand the same ultra-class transport, rebuild facilities and capital commitment. The D11 also cannot be scaled down if the site's production plan later changes.
Ans.
A lockup torque converter locks the transmission's fluid coupling solid during long pushes, instead of letting it slip. On the D155A-6 this cuts the fuel that would otherwise be lost as heat in the converter, and combined with selectable power and economy modes it improves fuel use over sustained dozing hours.
Ans.
The Cat D11 offers more ripper variety. It can be fitted with a single-shank or multi-shank ripper, plus specialty options like a multi-shank leach-pad ripper and a 5-shank coal ripper. The D155A-6 offers two configurations, a 3-shank ripper reaching 900 mm and a giant single-shank reaching 1,370 mm.
