Safe Durable Service Brakes
The WA1200-3 uses Komatsu-
designed sealed wet disc brakes. This
proven design, coupled with a brake oil
cooling system, provides reliable and
durable final drive braking while down-
hill traveling with full loads and in all
load and carry operations.
Quick Fluid Change-out System
Hydraulic oil, transmission/torque
converter oil, engine oil, and engine
coolant can all be changed from the
ground with a quickfill/change-out
system. A fast-fill fuel system is also
included as standard equipment.
Wiggins Quickfill systems are used.
Centralized Filter Layout
Torque converter, transmission, engine
oil, and fuel filters have been centrally
located for ease of replacement from
the ground.
Automatic Greasing System
A microprocessor-based system
ensures a preset supply of lubrication
is delivered to all lube points at the
proper intervals to help reduce
maintenance costs.
Steps, Ladders, Doors, Hinged
Radiator Grille, Handrails
Ladders and steps are arranged to
provide safe access to each mainte-
nance point. All doors are easy to
open and provide accessibility for
maintenance and cleaning. The
radiator grille is a hinged design
and opens as a door for easy access
and cleaning. Safety handrails and
steps are used at each maintenance
point above ground level.
Integrating the latest technology in all areas of design,
Komatsu has developed the WA1200-3 Mountain Mover
as the most reliable, durable wheel loader for working
in the harshest mining conditions.
Exclusive Komatsu Design
Features Power Train, Axles,
Transmission, and Hydraulic
Components
The power train transforms
1165 kW
1560 HP into
1127 kN 115000 kg
253,500 lb traction and
1274 kN
130000 kg
286,600 lb breakout force.
All components within the power train,
from bolts to final gearing, are all
Komatsu-designed.
Designed to bear large loads and
transmit large amounts of tractive
power, Komatsu’s full floating axle
is used along with its planetary style
transmission—another exclusive
Komatsu feature with proven industry
experience. The variable displacement
hydraulic pump and hydraulic cylinders
are also Komatsu-built components.
Rigid Frame
Frame is designed to accommodate actual working loads, and simulated
computer testing proves its strength prior to building.
To increase frame reliability, steel castings have been incorporated at all
frame pivot points to eliminate excessive welding lines.
