New 845 forwarder anchors Komatsu’s more powerful lineup

Komatsu has introduced a new lineup of forwarders that offers improved performance and operator comfort and includes a new 12-metric-ton model.

The four-model lineup includes the new 845 along with the updated 855, 875 and 895 models. Each of the new models are powered by Tier 4 Final engines and the three returning models feature horsepower and torque increases nearly across the board. Here’s a quick spec breakdown.

Komatsu says the engines powering these new forwarders also feature high torque backup, high capacity cooling systems and lower noise levels.

In addition to more powerful engines, the new forwarders are more capable in rough terrain thanks to larger hydrostatic transmission (HST) pumps and/or motors which increase tractive effort between 3 and 11 percent, depending on the model. Komatsu says the HST control unit on the machines continually responds to changes in terrain, load, engine power output and crane usage.

The forwarders feature 42-inch articulated steering, a V-shaped steel-frame bottom and a more than 1-inch increase in ground clearance over previous models. The front blade arm design has also been improved for better front-end ground clearance.

Komatsu F-series parallel cranes offer 14 percent more lifting torque and 32 percent more slewing torque over previous forwarders.
