E Economy ● Good cycle timesMode ● Good fuel economy

Hydraulics

Unique three-pump system assures smooth compound movement of thework equipment. OLSS (Open Center Load Sensing System) controls allthree pumps for efficient engine power use. This system also reduceshydraulic loss during operation.

Active and Economy mode

The PC1250-7 excavator is equipped with two working modes. Each modeis designed to match engine speed, pump speed, and system pressurewith the current application, giving the operator flexibility to match equip-ment performance to the job at hand.

Working Mode Selection

Heavy Lift Mode

Gives the operator approximately 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 the operator to use the same easy motionfor 180˚ loading as 90˚ loading operations. By altering the oil flow this set-ting allows you to select either boom or swing as the priority for increasedproduction.

Shockless Boom Control

The PC1250-7 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 PC1250-7 gets its exceptional power and work capacity

from its Komatsu SAA6D170E-3 engine. Output is

485 kW 651 flywheel HP providing more hydraulic power.

In addition, the fuel consumption is reduced by 13%

when using Economy Mode.

Noise levels are reduced for greater operator comfort.

Largest Bucket Capacity

Bucket capacity is the largest in its class and its large

opening and shallow bottom offers easy loading.

Improved Machine Stability

The center of gravity is moved rearward and the 18.0 tonne

19.8 U.S. ton counterweight provides the stability and lifting

capacity needed for maximum productivity.

Additional Features

• Large digging force

• Large drawbar pull

• Fast cycle times

Increased ReliabilityThe PC1250-7 incorporates many improvements in strength and reliability.

Frame structure. Plate thickness of the revolving frame and center frame

is increased and stiffener plates are added to improve durability.

The boom and arm have increased cross section and plate thickness,

as well as continuous both-side groove welding, improving digging

and side contact strength.

All of the major machine components such as engine, hydraulic pumps,

hydraulic motors, control valves, etc., are exclusively designed and

manufactured by Komatsu.

The undercarriage is strengthened

to provide excellent reliability and

durability when working on rocky

ground or blasted rock.

Metal guard rings protect all the

hydraulic cylinders and improve

reliability.

Heat-resistant wiring is utilized not

only for the electric circuit of the

engine, but also for other whole

units.

With the circuit breaker, the

machine can be easily restarted

after repair.

FEM stress analysis


Sturdy guards shield the travelmotors against damage from rocks.

MAINTENANCEFEATURES

MAINTENANCEFEATURESEasy MaintenanceKomatsu designed the PC1250-7 for easy service access. Wide walkways for maintenance

are provided around the engine and

hydraulic components, allowing

easy access for inspection and mainte-

nance points. Access doors open out-

ward, making inspection of the engine

and hydraulic systems easy.

Large service doors provide easy

access to the engine compartments.

(Photo shown with side door open to

front of engine).

Reduced Maintenance CostsReplacement intervals of engine oil,

engine oil filter, and hydraulic oil filter

are extended to 500 hours, and

replacement interval of hydraulic oil is

extended to 5000 hours.

6

Employment of DT-type connectorswhich seal tight and have higher reliability.

High-pressure in-line filtration. The

PC1250-7 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.

In-line filtration

Track roller guard (full length)(optional)

Machine Availability Is Increasedby Vehicle Health MonitoringSystem (VHMS) (Optional)

Vehicle Health Monitoring System

(VHMS) collects and stores operation

data of machine and major components

in real time. Collected data are not only

various kinds of machine data such as

engine oil temperature, engine exhaust

temperature etc, but also includes oper-

ating condition data such as fuel con-

sumption, engine load factor etc.

These data can be utilized by download-

ing personal computer to effectively

diagnosis machine health conditions.

Moreover, combined with EMMS func-

tion which displays error code, machine

and maintenance information on color

graphics screen (patent pending), VHMS

reduces maintenance time and increas-

es machine availability.

Orbit communication function

(Orbcomm) available as an upgraded

feature of VHMS enables remote moni-

toring of the machine condition.

Sturdy guards shield the pipingagainst damage from rocks.

The boom foot hoses are arranged

inside to reduce hose bend during

operation, extending hose life and

improving operator safety.

Operator’s CabSuperb Visibility

The PC1250-7’s large capacity cab and

increased glass area provide superb front

visibility.

Cab Mounts

The new cab damper mounting reduces

vibration and noise at operator’s seat.

Noise

The noise levels at the operator’s ear are

decreased by improving the cab mounts

and 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 maximum

productivity and comfort.

Pressurized Cab

Cab pressurization is increased to prevent

external dust from entering the cab with

optional air conditioner.

Automatic Air Conditioner(Optional)

A 6,900 kcal (SAE) air conditioner is

utilized. The bi-level control function keeps

the operator's head and feet cool and

warm respectively. This improved air flow

function 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 placed around high-temperature parts of the engine andaccessory drive.
