● Bucket Digging Power Is Increased 21%

Bucket Digging Power = Bucket digging force
x bucket speed. Bucket digging force is increased
9% and bucket digging speed is increased 12%, so
bucket digging power is increased 21%. (Compared
with PC220-6)

Easy Maintenance

● Replacement interval is extended for engine
oil, engine oil filter and hydraulic filter

● Remote mounted engine oil filter and
fuel drain valve for easy access

● Water separator is standard equipment

● Easier radiator cleaning

● Fuel tank capacity is increased

● BMRC bushings on work equipment

extend lubricating interval from
100 hours to 500 hours (optional)

See page 8 and 9.

● Low Noise

Noise is reduced not only from the engine but also

during swing and hydraulic relief. Dynamic noise level

is 104 dB.

● Environment Oriented Mode (Economy Mode)

Economy mode meets the needs of the 21st century.

Economy mode offers the user fuel savings, quiet

operation and less CO

emission.

● Fuel consumption is reduced 16% (compared with

Active mode).

● Production is the same as the PC220-6

Heavy-duty mode.

● Easily Recycled

PC220-7 is designed with consideration of recycling and

uses natural resources effectively.

● Sound suppressing material is made from PET

(polyethylene terephthalate) resin that is easy to recycle.

● All exterior parts are made from steel.

● Engine and hydraulic system oil and filter replacement

interval are extended to save earth resources.

● All resin-made parts are indicated by material code

symbol.

The increased output and fuel savings of the Komatsu

SAA6D102E-2 engine result in increased production and

improved production per unit of fuel.

Engine

The PC220-7 gets its exceptional power and work capacity

from a Komatsu SAA6D102E-2 engine. Output is 125 kW

168 HP, providing increased hydraulic power and improved

fuel efficiency.

Hydraulics

Unique two-pump system ensures smooth compound

movement of the work equipment. HydrauMind controls

both pumps for efficient engine power use. This system

also reduces hydraulic loss during operation.

Large Digging Height

PC220-7’s maximum digging height is 10 m 32'10",

facilitating jobs that require a longer reach, such as

demolition and slope finishing.

Larger Lifting Capacity

PC220-7’s lateral stability is improved, as a result, the

PC220-7 lifting capacity is

increased. Example: lifting

capacity over side (reach 6.1

m 20', height 4.6 m 15')

is increased from 4.45 ton

4.9 U.S. ton to 4.8 ton

5.3 U.S. ton.

Larger Digging Power Provides
Increased Production

Bucket Digging Power is obtained by bucket digging force x

bucket digging speed. New PC220-7 bucket digging force is

increased by 9% and bucket digging speed is increased by

12%, resulting total bucket digging power is increased 21%

(bucket digging force compared with PC220-6). The digging

force and speed generated result in the largest digging

power and the largest production in the 22 ton

24 U.S. ton class.

Three Working Modes

Working Mode Selection

The PC220-7 excavator is equipped with three working

modes (A, E and B mode). Each mode is designed to match

engine speed, pump speed, and system pressure with the

current application. This provides the flexibility to match

equipment performance to the job at hand.

Economy Mode

Economy mode is environmentally friendly. Fuel consumption

is reduced 16% (compared with PC220-7 Active mode)

and production is equal to the PC220-6 Heavy-duty mode.

Power Max Function

This function temporarily increases digging force by 7% for

added power in tough situations.

Working Mode Application Advantage

Excellent Reliability and Durability

Harmony with Environment

Grease Sealed Track provides excellent
undercarriage durability

Track Link with Strut

PC220-7 uses track links with
strut providing superb durability

● High Rigidity Work Equipment

The arm and boom are strengthened to correspond to increasing bucket and arm

digging forces. The arm and boom cross sectional strength are also increased

25% and 8% respectively. The boom and arm have large cross-sectional

dimensions as well as continuous groove welding, improving digging and side-

contact strength.

● Sturdy Frame Structure

The revolving frame, center frame and

undercarriage are designed by using the

most advanced three-dimensional

CAD and FEM analysis technology.

● Reliable Components

All of the major machine components,

such as engine, hydraulic pumps,

hydraulic motors and control valves, etc.,

are exclusively designed and manufactured by Komatsu.

● Highly Reliable Electronic Devices

Exclusively designed electronic devices

have passed severe testing.

● Controller ● Sensors

● Connectors ● Heat resistant wiring

● Metal guard rings protect all the hydraulic cylinders

and improve reliability.
