Features ویژگی ها
Komatsu-integrated design for the best value, reliability, and versatility. Hydraulics, power train, frame, and all other major components are engineered by Komatsu. You get a machine whose components are designed to work together for higher production, greater reliability, and more versatility.
SAA12V140E-3 turbocharged aftercooled diesel engine provides a net output of 664 kW 890 HP with excellent productivity. This machine is Tier 2 EPA, EU, and Japan emissions certified.
The Super Dozer
The D475A-5 Super Dozer greatly contributes to reducing operating costs ($/tons) by high dozing productivity.
Large capacity Super Dozer blade with low dozing resistance
Low noise
Operator noise: 70dB(A)
(Engine at high idle, cooling fan at 70%, and air conditioner OFF.)
Dynamic noise (outside): 110dB(A)
As per ISO 6395
Hydraulic Driven Engine Cooling Fan controlled automatically, reduces fuel consumption and operating noise levels.
Extra-low Machine Profile provides excellent machine balance and low center of gravity.
The Dual Tilt Dozer increases productivity while reducing operator effort.
Large blade capacity:
45 m³ / 58.9 yd³ (Super Dozer).
Automatic transmission with lockup torque converter increases speed and power to improve fuel consumption and productivity.
Track Link With Wedge Ring reduces maintenance cost by making turning pins easier, with improved pin reuse.
