SmartBoom
TM
Reduces stress and vibrations transmitted to the machine.
Rock Scraping. Scraping rock and
finishing work is easy and fast.
SmartBoom simplifies the task and
allows the operator to fully concentrate
on stick and bucket, while boom
freely goes up and down without
using pump flow.
Hammer Work. It has never been
this productive and operator-friendly.
The front parts automatically follow
the hammer while penetrating the rock.
Blank shots or excessive force on the
hammer are avoided resulting in longer
life for the hammer and the machine.
Similar advantages are applicable when
using vibratory plates.
Truck Loading. Loading trucks from
a bench is more productive and more
fuel efficient as the return cycle is
reduced while the boom down function
does not require pump flow.
Material Handling. It is more efficient and productive due to faster return cycles.
Unloading barges is easier because SmartBoom avoids excessive force being put
on the floor of the barge allowing the operator to fully concentrate on production.
Structures
Structural components are the backbone of the machine’s durability.
Carbody Design. The advanced carbody
design stands up to the toughest
applications.
Modified H-shaped, box-section
carbody provides excellent resistance
to torsional bending.
Variable gauge undercarriage has
track roller frames which are bolted to
the carbody and can be retracted for
shipping.
Robot-welded track roller frames with
fabricated U-section design.
Robot welding ensures consistent,
high-quality welds throughout the
manufacturing process.
Upper Frame. The rugged main frame
has been narrowed to improve
transportability and is designed for
maximum durability. Robot welding is
used for consistent, high-quality welds.
The main channels are box sections
connected by a large diameter tube in
the boom foot area to improve rigidity
and strength. The outer frame utilizes
curved side rails for rigidity against
bending and torsional loads.
Track Roller Frames. The track roller
frame is made of thick steel plate
that is bent into a U-shape and welded
to the bottom plate to create a box
structure. The box structure design
provides increased rigidity and impact
resistance.
Variable Gauge Undercarriage.
The long variable gauge undercarriage
is standard, providing a wide, stable
base for operating, or a narrow gauge
for reduced shipping width. The track
roller frames are bolted to the carbody,
and can be placed in two positions.
