Komatsu D475A-8 mining dozer offers more production and longer life
Komatsu D475A-8 mining dozer designed for exceptional production
Using extensive customer feedback, Komatsu re-engineered the D475A-8 mining dozer mainframe to target twice the life of previous models and withstand multiple rebuild/overhaul cycles. Its low center of gravity provides machine stability and long and consistent track on ground length offers more traction, pushing power, ripping efficiency and less shoe slippage. Track shoe slip control automatically controls engine speed and minimizes slip during ripping.
Komatsu D475A-8 mining dozer prioritizes operator comfort
Improvements to the operator’s cab make the Komatsu D475A-8 mining dozer more comfortable to operate throughout long shifts. Operators can ride in comfort with ergonomically placed touch points and palm control joysticks, outstanding operator visibility to the ripper shank, a rear view monitoring system and a heated, ventilated, air-suspended seat.
