MINI WHEEL LOADER

WA50-6

New high-power engine allows
any operation to be carried out
with minimal effort.

Featuring a new high-power and flexi-

ble Komatsu engine. Combined with

electronic control HST with minimum

power loss, Komatsu engine allows the

machine to perform any operation with

minimal effort.

Allows easy operation even in
narrow spaces. Excellent
machine operability and stability.

Short overhang structure and
increased articulation angle

Maneuverability has been increased

through a redesign of the chassis lay-

out. The machines prove their worth

when operated in narrow spaces.

(Machine with standard specifications)

Rear axle oscillation system

Following the uneven ground surface,

the rear axle oscillates to keep the

machine horizontal and stable. When

operated on rough roads, the swing

and vibration are minimized and you

can smoothly complete your work

while positioned on the comfortable

operator's seat.

Note: The photo at right was taken for advertising purposes only.

Do not leave your machine on a slope for security reasons.

Wheelbase Tread

Long wheelbase and wide tread

In addition to the short overhang struc-

ture, the machines feature long wheel-

base and wide tread providing excel-

lent stability both in operation and trav-

eling.

Wheelbase:

1900 mm 6'3"

Tread: 1250 mm 4'1"

Electronic control

HST

(Hydrostatic Transmission)

Electronic-control HST allows operation of the
machine as you desire.

The electronic-control HST allows any operator to start,

accelerate and stop the machine by using accelerator con-

trol only. Also, you can adjust the maximum travel speed

using the stepless speed control switch according to the

work you are engaged in.

The maximum rim pull

can be set to any of 3

stages using the traction

control switch to tailor the

machine to operating

conditions.

Speed control function

The maximum travel

speed can easily be set

from 3 to 15 km/h using

the speed control switch.

Max speed is infinitely,

variable up to 15 km/h to

give the operator option-

al control at all times.

Speed control switch

Traction control switch

Traction control function

The maximum rim pull can be set to any of 3 levels

according to the work you are engaged in.

P mode

Appropriate for operations

requiring an extra burst of rim

pull on demand such as ground

leveling, grading, excavating

and piling.

N mode

Appropriate for loading opera-

tions such as V-shape loading,

aggregate loading and load-

and-carry operation.

S mode

Appropriate for operations car-

ried out on soft and slippery

ground such as snow clearance

and livestock farming.

ATT mode

Reserved mode

Floor-mounted inching pedal allows easy machine
maneuvering for loading.

The floor-mount inching pedal puts the operator in full time

control of his machine. As the trav-

el speed is easy to control, you

can easily stop the machine at the

precise loading position.

Electric auto leveler allows
easy operation of the bucket.

When the bucket is lowered to the

ground, the bucket bottom becomes

level automatically.

Good dumping clearance and reach

The dumping clearance and reach of the machine allow for

efficient loading in to a dump truck or a hopper, and for

stockpiling work.

Dumping clearance:

2475 mm 8'1"

Dumping reach: 900 mm 2'11"
