Cat’s new S300B
scrap shear series
Caterpillar Work Tools B.V. has introduced
the new mobile scrap and demolition shears
S320B, S325B and S340B series for hydraulic
excavators. These shears extend the range of
B-series to the previously released S365B and
S385B shears.
“The performance and durability improvements
will further build on the already excellent
reputation of the S300 B shears,” said Caterpillar
Work Tools B.V. commercial manager Dave
Becktel. “With an emphasis on quality, value and
safety Caterpillar has improved on our already
excellent line of scrap shears.”
The shear and knife design improves cutting
performance and the hardened piercing tip of the
upper jaw maximizes productivity when piercing
is required. All S300 shear models are equipped
with 360° rotators ensuring a quick and precise
placement of the jaws in a cutting position without
moving the excavator. The high force-to-weight
ratio enhances faster cycle times, resulting in
more cuts per hour.
Cat shears are designed to cut and reduce
the size of metal items commonly found in scrap
yards and demolition sites. The straight lower jaw
works with the apex of the upper jaw, compressing
and flattening the steel before the cut. The
straight lower jaw maximizes shear force and

creates a more efficient cut.
The new shape of the housing provides
improved protection for shear components and
better positions the jaw relative to the stick.
The cutting edge design greatly improves the
protection of the cylinder that eliminates the use
of a cylinder guard by extending the housing to
cover the cylinder rod. A new hub design is better
protected against damage.
Large access panels on the top, bottom
and sides of the shear housing make it easier
to service. The unique hub adjustment quickly
compensates knife wear. The threaded pivot-pin
holds the jaw in positive alignment without the
need for external retention. The gap between
upper and lower jaw can be easily adjusted,
keeping cutting capability high, even as blades
wear. The piercing tip in the upper jaw is made
of hardened steel and can be repeatedly hard
faced, helping increase the intervals between
tip replacements.
Safety during maintenance work is enhanced
with improved jaw and rotation service locks. A
standard flagged pin is used to secure the cylinder
rod to the moving jaw. This pin design is very
similar to those used elsewhere on a Caterpillar
excavator and makes maintenance more intuitive
and lets technicians use standard tooling.
New special demolition recycling
machine from Sennebogen
Sennebogen is offering the new 830 R-HD
Special of the D Series for demolition works.
The 830 R-HD Special is a materials handling
machine that meets the heavy-duty requirements
of working all day. Due to the increasing
size of many projects the working height of
up to 17m combined with 3t lifting capacity
is a core advantage. This ensures that heavy
demolition tools can be handled easily at long
reach. Apart from the strong boom system the
special demolition equipment of the 830 also
includes the heavy-duty undercarriage.
For stability the undercarriage can be
hydraulically extended from 3m to 4.5m. The
360° rotating upper structure with positioning
brake, a special pipeline protection on the jib
and piston rod protection on the ULM cylinder,
are further equipment characteristics of the
Sennebogen 830 R-HD Special. Another useful
addition is the automatic high-pressure spraying
pump to minimise dust at the demolition tool.
Another standard feature is the tiltable
maXcab comfort cabin, which can be raised
to 4m for safe working and a perfect overview.
The Sennebogen 830 D Series can be very
quickly equipped with a grab or dipper shovel
and used as a fully functioning materials handling
machine. The longitudinal installation of the
engine, provides excellent accessibility of the air
filter and batteries and all daily servicing can be
done from the ground.

requirements.
The S320B, S325B and S340B series fit Cat
excavators weighing from 10t to over 60t. The
shears can be mounted on either the boom or
stick, and cater to all needs for scrap processing
and demolition applications.
Caterpillar supports its work tools with a
comprehensive range of before and aftersales
services that cover everything from advice on
work tool selection to operator training, equipment
management, and a range of financial and
insurance products.
