customers and dealers. This system is available
24 hours a day, all year round. All five electric
shovels come with the optional SkyAngle™
system designed to increase peripheral vision
around the excavator by providing synthesised
multiple images captured by cameras
specifically positioned at four locations around
the excavator. The feature displays camera
views on a single monitor to allow operators an
auxiliary means of checking for ground level
obstacles.
The EX-6 electric drive mining excavator front
attachments are made from welded steel plates,
not cast structures. The boom and arm are
welded from low-stress and high-tensile strength
steel for a full box section design. This rigid box
design resists twisting and bending forces.
The undercarriage design for the five new
models is the same as Hitachi’s popular Giant
EX Series. The track shoes incorporate a triple
grouser design and single roller; and roller
guides are used to extend service life for track
shoes. All models feature a filtered and
monitored hydraulic system that will monitor
and warn operators about machine hydraulic
health.
Komatsu designed its new 677 t PC7000
machine, also featured in IM March 2016, with
the aim of creating the safest and highest
performing shovel in its class. Powered by two
1,250 kW diesel engines, the Komatsu PC7000
can lift a 36 m³ front shovel bucket. Adapting to
different mining approaches and circumstances,
Komatsu also provides, in option, backhoe
attachments with a 36 m³ bucket and an electric
drive train.
By design, the shovel 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. On
request, data can be transferred via satellite
directly to maintenance
