Its low centre of gravity provides machine stability and long and consistent track on ground length offers more traction, pushing power, ripping efficiency and less shoe slippage.
The track shoe slip control automatically controls engine speed and minimises slip during ripping.
It has forward net horsepower of 664 kilowatt at 2000rpm and reverse net horsepower of 722kW at 2000rpm.
"Additional horsepower can provide for faster ground speeds, shorter cycle times and more production tons per hour, when appropriate," Komatsu said.
"The D475A-8's high horsepower in reverse means the lock-up converter stays engaged more frequently, allowing significantly higher levels of production, especially when pushing down slopes."
Komatsu said the D475A-8 mining dozer was designed for power, stability and solid performance.
"Komatsu's lockup torque converter produces a more efficient transfer of power to the driveline, designed to help decrease cycle times and increase production," it said.
"During long pushes the automatic gearshift mode allows the system to automatically engage the torque converter lockup clutch.
"Locking up the torque converter transmits all the engine power directly to the transmission, increasing ground speed and thus achieving efficiencies equal to a direct drive, consuming less fuel."
Improvements to the operator's cab are aimed at making the D475A-8 more comfortable to operate throughout long shifts.
"Ergonomically placed touch points and palm control joysticks make operation easier," Komatsu said.
"Outstanding operator visibility to the ripper shank, a rear-view monitoring system and a heated, ventilated, air-suspended seat help keep operators comfortable.
"The redesigned undercarriage of the D475A-8 drastically reduces shock and vibrations when the dozer travels over rough terrain."
Komatsu said operators could boost efficiency by working in blade auto-pitch mode, which was designed to increase dozing efficiency while reducing operator input.
"The all-new blade support structure is designed to significantly reduce blade side sway," it said.
"It also has fewer maintenance points and enhances operator visibility to the blade.
"The D475A-8 is engineered to minimise planned downtime and make maintenance efficient with features such as centralised greasing points, ground-level fill and evac service centre, and battery and starter isolators with lockout tagout functionality."
