Today’s mines around the world need larger machines to provide

improved productivity and economy within their operation. Simple

size increases can’t achieve this. Komatsu has responded to this

need with larger, more productive machines which incorporate

leading edge technologies. In keeping with Komatsu’s motto “always

respond to customer needs with the most advanced equipment

available,” the

MOUNTAIN MOVER WA1200-3 was born.

The Most Advanced Technology

Safe boarding and exiting
machine. Boarding stairs are

equipped with safety handrail
and step lights for night operation.

The dream has come true.

Advanced Joystick Steering System
(AJSS) with light, short strokes
for perfect steering accuracy.

Remote boom positioner is easy to set up.
High and low bucket positions are easily set up
promoting smooth bucket movement stops
without shocks to machine components.

Hi-Cab is extra long and wide to
provide a comfortable work environment.
The seated operator has a better view
inside the body of a 240-ton haul truck.
Oversized, obstruction-free windshield,
side and rear windows provide a
panoramic view of the work site.

Overhead panel

for cassette/radio and
air conditioner controls.

Safe maintenance accessibility. All maintenance
points are equipped with a step and safety handrail.
Engine radiator grille pivots open for easy access.

Variable traction and hydraulic power. Variable Output
Hydraulic System (VOHS) is a self-adjusting hydraulic system
to meet system demand for high productivity.

Breakout force:

1274 kN 130000 kg 286,600 lb

Traction force:

1127 kN 115000 kg 253,500 lb

RPM set system

allows engine speed to
be easily set with a gentle
momentary touch.

Quick fluid change-out system:

hydraulic oil, transmission/
torque converter oil, engine
oil, engine coolant, and fuel.

Emergency
brakes/emergency
steering.

Selectable traction power.

● Maximum traction control for
adjusting the traction to suit the
conditions at various operations.

● Maximum speed control of 1st and
2nd travel speeds to help shorten
cycle times and extend tire lives.

Longer tire life. Tire Saver controls tire slip
and lengthens tire life. Optional wide base tires
(65/65-57 62PR) offer longer service life than
standard tires.

Multi Monitor

serves as a service information center.
It has gauge, maintenance, load meter,
and remote boom positioner and
service functions.
