With the introduction of the PC750, Komatsu has brought the field-proven performance of the Avance Dash 6 series to the 80-ton excavator class. By combining unrivaled control with outstanding productivity, Komatsu continues the tradition of setting new industry standards.

Three working modes let you match engine speed, pump speed, and system pressure to the current application.

High pressurehydraulic systemprovides fast cycle times and smooth operation. Two mode settings

for the boom allow you to select either a smoothtrench floor or aggresivedigging in tough materials..

Strengthened hydrauliccylinders provide outstandingreliability.

Swing accel function maximizes efficiency and boom control for 90°or 180° loading operations.

PC750 Features● Fast and smooth hydraulics

● Excellent digging performance

● Outstanding machine stability

● Large drawbar pull

● High engine output

● Large bucket capacity

● Excellent transportability

Together, these features make the

PC750 the most productive excavator

in its class.

For the operator the PC750

combines the following:● Low noise design

● Spacious cab

● Easy routine maintenance

● New controls for boom vibration

● Unrivaled control

● New safety features

Self-Diagnostic Monitor

The improved Avance monitor is equipped with an on-board self-diagnostic system.

This diagnostic system can display information for the following:

● Current operating conditions—engine speed, hydraulic main pump pressures,

and electronic signals.

● Historical abnormalities—records up to 20 deviations within the past

1,000 hours of operation.

If an abnormality occurs, the system will display a warning or sound an alarm.

Outstanding Reliability

The latest in computerized stress

analysis is combined with field testing

to ensure that each component from

the frame to the electronics delivers

superb reliability. The hydraulic

system features:

● High pressure in-line filters to protect

the hydraulic system from coarse

contamination

● PPC filter to protect control circuits

● Strengthened hydraulic cylinders

● Stepped hose connections to

prevent leaks

● Strengthened work equipment

● Strengthened track frame

Easy Maintenance

● One-touch engine oil drain valve

● Main relief valve quick couplers

facilitate troubleshooting hydraulics

● Extended oil and filter drain intervals

from 250 to 500 hours for engine

Four Diagnostic Modes

Time Display mode is thedefault mode and shows the timeand hour meter reading.

User Code Display modedisplays a trouble code and soundsan alarm when a problem has beendetected.

Trouble Data Memory modemonitors 32 separate items andstores up to 20 abnormalities over 999 hours for effectivetroubleshooting.

Together, these modes allow you to troubleshoot 119 differentproblems to minimize downtime.

Self-DiagnosticMonitor

The LCD portion of the monitor has four different display modes thataid in identifying potential problemsbefore they become major problems:

Three Working Modes

Heavy Lift Mode

Travel Speeds

Travel Speeds

The Avance excavator is equipped with two travel speeds to provide

smooth, efficient travel around the job site.

Swing Accel

The swing accel function is designed to control boom and swing

speeds to provide optimum responses for different loading angles.

As a result, operators can use the same easy motion for 180° loading

as they do for 90° loading.

Unrivaled ControlTwo-Mode Setting for Boom

By pushing a button, it is possible to select either a smooth

arm operation or powerful boom digging force. Based on your

selection, the system chooses the boom head relief valve

pressure from two available settings.

Easy OperationWorking Mode Selection

The Avance excavator is equipped with three working modes. Each

mode is designed to match engine speed, pump speed, and system

pressure to the current application.

Heavy Lift

Working Mode Application Advantage

● Maximum production/powerH/O Heavy-duty● Fast cycle times

● Good fuel economyG/O General● Good cycle times

● Increased powerDH/O Hard-rock ● Quicker engine response to

sudden load changes

Selection Application Result

OFF Normal Standard operating pressure

ON Heavy lifting Increased working pressure by 10%

Selection Result

ON Oil flow to the swing motor is increased.180° loading operations are most efficient.

OFF Oil flow to the boom is increased.90° loading operations are most efficient.

WORKINGENVIRONMENT

WORKINGENVIRONMENTThe Avance® cab interior is spacious

and provides a comfortable working environment…

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.

Cab Mounts

The cab rests on viscous damping mounts to reduce vibration and noise

from the machine body. Operator fatigue is reduced.

Noise

The noise levels at the operator’s ear have been decreased by improving

the cab mounts, and reducing engine operating noise.

The multi-position diagnostic monitor is easily reached and can be rotated

to remove glare. Plus, the inclined dashboard makes the switches and fuel

control dials easier to view and use.


Safety FeaturesThe PC750 has been designed formaximum safety and convenience:

● Travel alarm

● Large handrails

● Step light for cab exits at night

● Large catwalk

● Fire partitions between hydraulicpumps and engine room

● Interconnected horn and lights(optional)
