Allows steering and directional travel to be controlled by wrist and finger control to minimize operator fatigue in high duty cycle applications. AJSS allows for full speed travel speed while maintaining precise steering and control.
Boom and bucket automatically raise, removing the need for operators to move levers to fill the bucket.
The newly designed bucket improves overall machine productivity. Generous curves on the side wall and wrap improve pile penetration and make it easy to fill. They also improve material retention in carry operations.
The Load Meter displays what material weighs in the bucket. Only available in two-valve/two-lever machines.
The printer generates a ticket (or receipt) telling the operator the weight of the material deposited into the loading truck.
A new air suspension seat provides enhanced support on rough roads and dampens machine vibrations, providing a more comfortable ride for the operator. An EPC lever console is integrated in the seat and moves with the seat. The angle of the armrest is fully adjustable for optimum operator comfort. A secondary F-N-R switch is incorporated in work equipment lever configurations. A heated seat is standard.
The Komatsu SAA6D125E-7 engine is EPA Tier 4 Final
emissions certified and provides exceptional performance
while reducing fuel consumption. Based on Komatsu
proprietary technologies developed over many years, this
new diesel engine reduces nitrogen oxides (NOx) by
more than 80% when compared to Tier 4 interim levels.
