Working Mode Selection
Heavy Lift Mode
Gives the operator 10% more lifting force on the boomwhen needed for handling rock or heavy lifting applications.
Two Settings for the Boom
Smooth mode provides easy operation for gathering blasted rock andscraping operations. When maximum digging force is needed, switch topower mode for more effective excavating.
Swing Priority Setting
The swing priority setting allows theoperator to use the same easy motion for180˚ loading as 90˚ loading operations.By altering the oil flow, this setting allowsyou to select either boom or swing as thepriority for increased production.
Shockless Boom Control
The PC750-7 features a shockless valve (double-check slow return valve) that automatically reduces the amountof vibration present when operating theboom. Operator fatigue is reduced(which can improve safety and productivity), and spillage caused by vibration is prevented.
Two Working Modes
Heavy Lift Mode
Engine
The PC750-7 gets its exceptional power and work capacityfrom its Komatsu SAA6D140E-3 engine. Output is 338 kW 454 HP providing more hydraulic power.In addition, the fuel consumption is reduced by 12% when using Economy Mode.
Large Digging Force
Thanks to the high engine output and an excellent hydraulicsystem, this machine demonstrates powerful digging force.
Large Drawbar Pull and Steering Force
Since the machine has a large drawbar pull and a high steer-ing force, it demonstrates excellent mobility even when it isbeing used on inclined sites. In addition, this machine isequipped with an automatic travel speed shifting system,which makes automatic Hi/Lo shifts.
Excellent Swing Performance
Twin-swing motor system of PC750-7 provides excellentswing performance on slope.
Excellent Machine Stability
The rear center of gravity and the 9.8 tonne 10.8 U.S. ton counterweight provides the stability and liftingcapacity needed for maximum productivity.

DT-type connectors seal tight andhave higher reliability.
High-pressure In-Line FiltrationThe PC750-7 has the most extensive
filtration system available, providing
in-line filters as standard equipment.
An in-line filter in the outlet port of
each main hydraulic pump reduces
failures caused by contamination.
Track roller guard (full length)(optional)
Boom Foot HosesThe boom foot hoses are arranged
under the boom foot to reduce hose
bend during operation, extending hose
life and improving operator safety.

KOMTRAX® System (optional)
The KOMTRAX system monitors
machine condition, operating status,
operating location, etc., and provides
timely notification of any machine prob-
lems.
Since data is transmitted via satellite
communication system, secure data
communication is possible from any
operating site including a quarry or a
mine, further improving machine relia-
bility.
(There are some countries where this
feature is not in service. Please consult
Komatsu distributor for availability.)Metal Guard RingsMetal guard rings protect all the
hydraulic cylinders and improve
reliability.
Heat-Resistant WiringHeat-resistant wiring is utilized for the
engine electric circuit and other major
component circuits.
Circuit BreakerWith the circuit breaker, the machine
can be easily restarted after repair.

Superb Visibility
The PC750-7’s large capacity cab andincreased glass area provide superb front visibility.
Cab Mounts
The new cab damper mounting reducesvibration and noise at operator’s seat.
Suspension seat
The suspension seat has been improvedto reduce and absorb vibration transmittedto the operator. Rigidity adjustment, fore
and aft sliding, as well as up and downadjustment is available to accommodatethe body-build of operators.
Low Noise Design
The noise levels at the operator’s ear aredecreased by improving the cab mountsand cab sealing performance.
Multi-Position Controls
The multi-position, pressure proportional control levers allow
the operator to work in comfort while maintaining precise control.
A double-slide mechanism allows the seat and controllers to move together or independently, allowing the operator to position the controllers for maximumproductivity and comfort.
Pressurized Cab
The optional air conditioner, air filter, and ahigher internal air pressure (6 mm Aq0.24" in Aq) prevent external dust fromentering the cab.
Cab with fixed front window (optional)Internal air pressure : 10 mm Aq 0.39" in Aq
Automatic Air Conditioner (optional)
A 6,900 kcal air conditioner is utilized. The bi-level control function keeps theoperator's head and feet cool and warmrespectively. This improved air flow func-tion keeps the inside of the cab comfortable throughout the year.
The cab interior is spacious and provides a comfortable working environment…
Seat belt shown in photo is optional.
Thermal guards are placedaround high-temperatureparts of the engine andaccessory drive.
