Built-in ROPS/FOPS

These structures conform to ISO 3471 and SAE J1040-1988C

standards.

Hydro-pneumatic Suspension for all Terrains

The hydro-pneumatic suspension assures a comfortable ride

even over rough terrain and ensures maximum productivity

and operator confidence.

Viscous Cab Mounts

Viscous mounts reduce the noise transmitted to the cab and

achieve a quiet 76 dB(A) noise level

Air Suspension Seat

to the operator’s weight is provided as standard. The air 

suspension seat dampens vibrations transmitted from the

machine and reduces operator fatigue as well as holding the

operator securely to assure confident operation.

Electric Body Dump Control Lever

The low effort lever makes dumping easier than ever.

Supplementary Steering and Secondary Brakes

Supplementary steering and secondary brakes are standard

features.

Wide, Spacious Cab with Excellent Visibility

The wide cab provides a comfortable space for the operator

and a full size buddy seat. Large electrically operated windows

and the operator’s seat positioned to the left side ensures

superior visibility.

Ergonomically Designed Cab

The ergonomically designed operator’s compartment makes

it very easy and comfortable for the operator to use all the

controls. The result is more confident operation by operators

and greater productivity.

Easy-to-See Instrument Panel

The instrument panel makes it easy to monitor critical

machine functions. In addition, a caution light warns the

operator of any problems that may occur. Problems are

recorded in the monitor and indicated as service codes.

This makes the machine very friendly and easy to service.

Steering Wheel and Pedals

Low effort pedals reduce operator fatigue when working 

continuously for long periods. The tiltable, telescoping steering 

column enables operators to maintain the optimum driving

position at all times.

Komatsu has developed a state-of-the-art, wide comfortable cab.  The low level of
vibration and noise ensure maximum productivity from the operator.
