ATLAS COPCO CONSTRUCTION TOOLS
Solid-body hydraulic breaker
Atlas Copco says its new SB 702 hydraulic breaker is the world’s only 700 kg hydraulic breaker with a solid body,
making it compact and easy to handle. The percussion mechanism and guide system are integrated into a single
block of steel, eliminating the need for side bolts. The integrated, maintenance-free accumulator is easily accessible,
yet well protected from bangs and knocks. The unit works with a wide oil flow range and can be installed on a broad
variety of carriers. Double tool-retainer bars minimize stress and wear on the working tools. Energy recovery helps
to absorb recoil, resulting in less wear and tear on the carrier and more comfort for the operator.

BREAKER TECHNOLOGY, INC.
How we made
When we ask readers how we can best
help them keep track of changes in the
products and services they use to produce
aggregates, almost everyone wants an annual short list of the really important stuff.
No wonder. The sheer volume of introductions is overwhelming. Aggregates Manager
covers dozens of products each year in its
RollOuts departments and Supply Lines
So each year, our staff reviews all the
product introductions we’ve covered for
the past year (our Top RollOuts “year”
actually runs from the December 2011
issue through the November 2012 issue)
to pick out 25 that we believe are worth
further review. Our priorities are new concept products, which are rare; new series/
new generation products in categories
that relate to the aggregates industry; and
other rollouts which serve our readers’
interests by increasing competition in a
Inevitably, we omit deserving products,
either because we just didn’t understand
the significance of the product or because
the announcing company didn’t communicate what was special about the product,
or both. In either case, we apologize in
advance for these omissions.
Next-generation boom system
BTI’s new high-velocity control (HVC) boom system provides “fly
by wire” computer-assisted control, allowing simultaneous dip and
hoist functionality. This is said to enable greater production through
rapid, smooth motion into and out of the gyratory crusher rock box.
The “smart” boom features a high-horsepower electric motor, high
flow-rate pumps with constant horsepower control, a high-flow directional control valve, and an electrical boom position feedback for
speed and pressure control. Breaker Technology, Inc.; rockbreaker.com.

CASE CONSTRUCTION EQUIPMENT
Case’s new 621F wheel loader features
a 6.7-liter Tier 4 Interim engine that
delivers up to 162 horsepower. A new
dual-mode shutdown feature maximizes
fuel economy and monitors vital engine
components. The operator can limit idle time by using the fuel-saver mode; desired shutdown time
can be set in five-minute increments. The loader includes standard limited-slip front and rear axles
for traction in all conditions. Operators can move seamlessly between the joystick and steering wheel.
The PowerInch feature maintains high RPMs to maximize hydraulic power and control. The cab offers an unobstructed view to both edges of the bucket; a wide window and sloping hood provide clear
vision to the rear. Case Construction Equipment; www.casece.com. Text INFO to 205-289-3782 or visit aggman.com/info.
