Komatsu D155A-6 vs Komatsu D475A-5E0: entry-level mining dozer or ultra-class giant?
The Komatsu D155A-6 and the Komatsu D475A-5E0 sit at opposite ends of Komatsu's mining dozer range. The D155A-6 runs 360 HP with a 9.4 m³ blade, while the D475A-5E0 runs 890 HP with a 27.2 m³ blade, close to three times the blade capacity. The D155A-6 turns in a far tighter radius of 2,140 mm against the D475A-5E0's 4,600 mm, and it also has more blade tilt adjustment, at 950 mm against 770 mm, despite being the much smaller machine.
Choose by the scale of your operation. A contractor stepping up from construction-class equipment into mining-class ownership finds a practical, manoeuvrable starting point in the D155A-6. A large opencast mine already running continuous, ultra-class overburden production needs the D475A-5E0's far greater blade volume and fuel range. Both are mining dozers in our dozer range; the bulldozer guide can help you size the right class.
Komatsu D155A-6
Pros:
Turns in a far tighter radius of 2,140 mm for confined pit corners
Lower ground bearing pressure, sinks less on soft ground
More blade tilt adjustment at 950 mm than the much bigger D475A-5E0
Two ripper choices, multi-shank or giant single-shank
Practical entry point into mining-class dozer ownership
Cons:
Far less powerful at 360 HP against the D475A-5E0's 890 HP
Much smaller blade at 9.4 m³ against 27.2 m³
Smaller fuel tank at 625 litres against 1,670 litres
Not built for continuous ultra-class production volumes
Komatsu D475A-5E0
Pros:
Far more powerful at 890 HP with a 27.2 m³ blade
Much larger fuel tank at 1,670 litres for extended shifts
Choice of giant single-shank or 3-shank multi-shank ripper for the heaviest breaking work
AC cabin standard rather than optional
Built for the largest continuous overburden production in opencast mining
Cons:
Much wider turning radius at 4,600 mm, far less nimble in tight spaces
Higher ground bearing pressure, sinks more on the same ground
Less blade tilt adjustment than the far smaller D155A-6
Sized well beyond smaller or mid-scale mining needs
Pros:
Cons:
Closing Recommendation
The Komatsu D155A-6 suits a contractor stepping up from construction-class equipment into mining-class dozer ownership, where a smaller, tighter-turning machine still handles the job. The Komatsu D475A-5E0 suits the largest opencast mining operations that need Komatsu's highest blade capacity and drawbar push for continuous production. So match the machine to your work: Komatsu D155A-6 for a first step into mining-class ownership, Komatsu D475A-5E0 for the largest continuous overburden production.
Komatsu D155A-6 Vs Komatsu D475A-5E0 Dozer Price, Technical Specifications & Features
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.
The Komatsu D475A-5E0 is a 108.4-tonne mining crawler dozer with an 890 HP engine. Its 27.2 m³ blade handles very large material volumes, while tractor-only ground bearing pressure is 128 kPa and reaches about 166 kPa in full operating trim. Two ripper configurations are available for different breaking requirements. The variable giant single-shank reaches 1,744 mm, while the 3-shank multi-shank setup covers wider ground. The choice therefore depends on whether the operation needs deeper breaking or broader coverage. A 1,670-litre fuel tank supports extended working shifts, and 655 mm of ground clearance suits rough mining surfaces. The machine is the largest of Komatsu's listed mining dozers. Coal and metal mining are its primary applications rather than general construction. Large mining operations can consider this dozer machine when production requirements have moved beyond the D375A-6. Its blade capacity can reduce the number of passes required across large cuts. Buyers can select the ripper arrangement according to the expected ground conditions. The operating weight and power make it suitable for very large-scale pushing and ripping work. For mining fleets requiring Komatsu's highest listed crawler dozer capacity, the D475A-5E0 provides the largest option.
