Komatsu Mining has released its “next generation” in

mining shovels, the PC7000, a 700 tonne class machine

available in face shovel and backhoe configurations.

It is matched to plus-200 tonne trucks such as

Komatsu’s 830E, 860E and 930E haul units.

The Komatsu PC7000 is designed to meet the mining

industry’s requirements for high productivity and offers

lowest cost per ton in its class.

With Komatsu customers’ requirements clearly de-

fined, the development of the Komatsu PC7000 began.

Komatsu designed this 677 ton machine with the aim

to create the safest and highest performing shovel in its

class.

Powered by two 1250 kW diesel engines the shovel

can lift a 36 m³ (47 yd³) front shovel bucket. Adapting

to different mining approaches and circumstances,

Komatsu also provides, as an option, backhoe attach-

ments with a 36 m³ (47 yd³) bucket and an electric drive

train.

By design, the shovel perfectly matches 240 to 290

short ton trucks such as the Komatsu 830E and Komatsu

860E. Operators will experience improved ease when

digging and bucket filling as Komatsu reviewed both the

bucket design and hydraulic layout.

With the new open circuit, hydraulic system the

shovel swings faster and penetrates the material

easier.

Reduced maintenance time, thanks to increased

width of walkways and repositioning of major service

points for easier access, was taken into account when

scheming the shovel. Komtrax Plus, the latest Komatsu

machine monitoring system, is installed on the machine

and lets customers check the operating status of their

machine.

Safety matters

Continuing to improve machine and human safety,

Komatsu developed a new safety concept for this new

machine. The Komatsu PC7000 is equipped with an il-

luminated 45° primary access and egress stairway.

In case of emergency, a solid anti-slip, flip-down

ladder provides secure egress from the cab and machin-

ery house. In addition, Komatsu has upgraded the light

arrangements to LED technology for brighter and safer

service and operation.
