Operator environment Cab

Modern design and new styling

Round glass surfaces

Excellent visibility all around Wide doors for a better access

Lower position of the cab: only 3

steps to enter

Larger cab

All flat glasses

Doors have openable windows

that reduce side visibility Smaller entrance doors

Cab position is higher with 4 steps

to enter: not an easy access

Operator environment Cab

Strong and protecting roof

All the windows have a strong

metallic frame for a better glass

protection

Front and rear side windows aremounted without frame: higher

possibility of damage


7/38


Operator environment Front visibility

Excellent visibility to the front

working area thanks to the sloping

engine bonnet and exhaust gaspipe at cab side

Exhaust gas pipe and high engine

bonnet reduce visibility to the

front working area

Loader is not very visible

Less central visibility due to

mono-link cylinder

Operator environment Upper front visibility

Upper window gives a perfect

visibility in high position for

loading operations

Loader is completely visible

No upper window available

Loader is not completely visible

Operator environment - Seat Sensor

Not available The Safe Position seat sensor

warns with an acoustic alarm the

operator when the seat is out of

the Loader position and the

Fwd/Rev shifter is activated

This application complies with the

European Standard (EN 474-3)

19/38


Backhoe - Bucket

Only 1 digging position: no

customisation

2 digging positions:

1) close to bucket teeth: plinth

digging (vertical digging)2) far from bucket teeth: higher

force and bucket rotating angle

Backhoe - Stabilisers

The upper part of the stabiliser is

protected by a rubber cap

Stabilisers are adjustable from 2sides

The upper part of the stabiliser is

not covered: mud and dirt can

enter

Stabilisers are adjustable only

from 1 side

Komatsu CLSS (Closed Load

Sensing System) : more power to

the working equipment at any

engine rpm

LIFD (Load Independent FlowDivider): the system forces the oil

to all circuits regardless the

different load

bonnet

All checks and filters are well

grouped and easy to reach

Maintenance is possible also with

the loader arm lowered

One piece tiltable bonnet with

internal insulation

There is no handle to raise the

bonnet Filters are on the right and checks

on the left

Serviceability Radiator


35/38


Serviceability - Radiator

2 different radiators, one in front

to the other

Hydraulic oil radiator is tiltable:

system used by Komatsu in thepast

More complicate to clean

1 radiator, with 3 separate

sections side-by-side, aluminum

type (T/M oil, engine water,

hydraulic oil)

Easy to clean

Better structure and quality

Radiator is mounted on 4 elastic

supports
