Crawler Dozers

D375A-8

Outstanding productivity and enhanced ride performance.

The Komatsu D375A-8 73 tonnes crawler dozer is safe, fast, powerful and efficient addition to any customer’s fleet. Its unrivalled level of comfort allows you to fully utilise the machine’s potential.

For greater efficiency during long pushes, the torque converter lockup clutch can be automatically engaged. Engine power is then sent directly to the transmission, increasing ground speed and machine efficiency, for less fuel consumption and faster cycle times.

Combined with the automatic transmission, the Komatsu automatic lock-up torque converter reduces fuel consumption by up to 10% by eliminating unnecessary power loss. When required, the powertrain control system engages the torque converter, or locks it up to send full engine power directly to the transmission during less torque demanding applications.

First-Class Comfort
Operator comfort is essential for safe and productive work. The newly designed cab on the D375A-8 is quiet and comfortable, an ideal environment to concentrate on the job. Its hexagonal design and large tinted glass windows offer excellent panoramic visibility. The high capacity climate control system pressurises the cab to keep dust out. A high quality sound-absorbent lining covers the interior to minimise noise levels for the operator.

Working mode can be set to either “Power” for maximum power or to “Economy” for energy saving operations. The Komatsu Diesel Particulate Filter (KDPF) captures more than 90% of Particulate Matter (PM). To reduce unnecessary fuel consumption and exhaust emissions, and for lower operating costs, the Komatsu auto idle shutdown automatically turns off the engine after it idles for a set period of time.
