Kobelco
develops SK3500D building demolition machine. 65-meter
working range is world's highest
TOKYO,
October 24, 2005 - Kobelco
Construction Machinery Co., Ltd. has developed a
building demolition machine that has the world's highest
working range of over 65 meters. Marketing of the machine,
which will be sold only domestically, begins today.
Japan's
largest demolition company, Watanabe Kaitai Kogyo (Nabekai)
has already placed an order for the first machine. With the
machine completed, Kobelco has applied to Guinness World
Records to register the SK3500D as the demolition machine
with the highest reach in the world.
SK3500D
In
recent years, Japan has been undergoing extensive urban
redevelopment. Old buildings are being torn down and
properties rebuilt to make effective use of urban spaces.
Building demolition has become increasingly difficult, due
to the height of buildings, the use of large concrete
foundations, and the high strength of the concrete in
buildings.
Building
demolition equipment is commonly built on a 40-ton-class
hydraulic excavator base machine and has a reach of about 25
meters, high enough to handle a seven- to nine-floor
building. For jobs that require a higher reach, a crane is
used to hoist the demolition equipment to the roof of the
building to be demolished, and the building is dismantled
from the top down. This invariably increases the amount of
work and number of days required to complete the job. For
these reasons, demolition companies have been seeking a high
performance machine with a longer reach that can be operated
from the ground.
To
meet these needs, Kobelco developed the SK3500D, which has a
working range of over 65 meters, about the height of a
21-story building. The SK3500D is built on a 200-ton crawler
crane carrier. The wide span and low center of gravity
contribute to the safe and efficient dismantling of
high-rise buildings.
The
SK3500D has a high-output power plant used in excavators,
makes use of attachments from Kobelco's extensive menu, and
is equipped with an ultra-long arm.
In
addition to high-rise building demolition, the SK3500D can
dismantle smaller buildings by changing the front attachment
or crusher. Machine operating rates have been improved to
more efficiently bring down low-rise and medium-height
buildings.
Main
Features:
1.
World's highest working range of 65.03 meters
*
A
three-piece boom and 4-piece attachment gives the
SK3500D the world's highest working range of 65.03
meters.
*
The
SK3500D can directly dismantle a 21-story building
from the ground.
2.
Ultralarge 12-ton crusher can be attached
*
An
ultra-large 12-ton crusher, with a maximum reach of 41
meters, can be used in place of the three-piece
attachment.
*
Other
attachments developed are the ultra-large concrete
crusher KR1600TPR and steel beam cutter KS1300TPR.
*
These
attachments, used with the SK3500D, can efficiently
dismantle low-rise and medium-height buildings.
3.
Attachment assembly & disassembly are easy and safe
*
Using
a built-in hydraulic "quick-hitch" developed
by Kobelco (and under patent application), the
attachment can be taken apart into six components.
Assembly and disassembly are easy and safe.
*
Quick
couplers are used to efficiently connect the hoses.
4.
Easy disassembly and transport at the work site
*
Disassembly
and assembly of the base machine is made easy through
a crawler frame disassembly system using hydraulic
cylinders and translifters.
*
The
swinging and tilting cab clears width limitations of
the machine during transportation.
*
The
base machine can be disassembled into over 17
components to fit the carrying capacity of the
trailers.
5.
Safety features for high-rise operations
*
Anti-drift
Boom and Arm Holding Valves prevent the boom
from suddenly dropping if the hydraulic lines
malfunction. All cylinders are equipped with
counterbalance valves. The Inclination Alarm
alerts the operator when the base machine angles too
steeply. The Tip-over Alarm automatically
monitors the position of the arm to warn the operator
before the machine tips over.
*
A
camera on the boom enables the operator to view
attachment operations. A rear-view camera on the back
of the SK3500D enables the operator to monitor
activity behind the machine. Both come as standard
equipment.
6.
Noise and dust reduction
*
In
addition to low-noise design, the SK3500D has a water
hose running from the base machine to the arm tip.
Water is sprayed during dismantling operations to
reduce dust.

Kobelco's
new 100 ton class large-sized building dismantling machine.
The Kobelco building machine corporation recently introduced
a powerful, large-sized 100 ton class building dismantling
machine called "SK950LCD".
Kobelco said: "The industry was asking for this kind of
machine for a long time.
Dismantling jobs have become more and more complicated as
buildings are getting higher and bigger. Also the higher
strengthening of the fundamental structure itself is
becoming a bigger problem.
With the effective use of the city space, redevelopment
works in the urban district, have also become difficult due
to the narrow area of the demolition site itself. Also
transporting equipment to these sites is a "hell of a
job". For this kind of city dismantling jobs Kobelco
developed it's special High Reach Demolition program.
Kobelco has listened very good to it's costumers over the
years, and still offers the largest range of HRD products in
the world.
Still missing in the program was a machine that was capable
of cracking heavy reinforced concrete and heavy steel
structures, at bigger heights (20-30mtr.).
Steel structures are mostly cut on ground level and then
pulled down. But in many places that's not allowed or not
even possible, so cutting has to be done by hand, which
takes a lot of time, and is considered dangerous.
The same problems occur with the bigger industrial
buildings. As they are being build with higher strengthening
of the fundamental structure itself, the dismantling of
these buildings have become a problem. Big machines can not
reach the higher floors and the high reach machines can not
crack the heavy thick concrete. This is why the industry
needed a new kind of High Reach Dismantling machine. The
SK950LCD is one of it's kind in the world and offers just
that!".
(1)
A powerful and efficient dismantling job
-
The wide operation range using the machine without
the extra reach mid section:
The machine
can be used on ground level also. So no other
machine is needed for separating material, loading
material or cracking the lower levels.
-
With the extra reach mid section it means; bigger
job height.
The extra
reach mid section offers bigger job heights. It
allows you to dismantle 7 - 9 floor buildings.
-
The high workforce:
The
reinforced concrete structure and the fundamental
part of the building can be cracked efficiently and
with greater speeds because the machine can be equipped
with bigger and heavier attachments.
-
Use in narrow spots:
Because of
it's outside turning radius the machine can be used
in narrow jobsites as well.
(2)
Easy to use
-
Hydraulic
pins are built-in for easy/quick removal and
re-installation of the booms.
-
Easy

Your arsenal: a
variety of attachments are being put to work on demolition sites as
controlled
demolition grows in popularity. As controlled
demolition--using a high-reach hydraulic excavator fitted with a
variety of attachments to carefully demolish a building--gains
popularity in North America, so does the importance of having the
appropriate battery of attachments to perform a variety of tasks
common to many demolition sites.
When coupled with a hydraulic excavator, or even compact excavators
and skid steers, the right attachments can increase a demolition
contractor's productivity on site and make the recycling of those
materials that much easier.
AIMING HIGH
"I think the high-reach systems are a safer and more economical
alternative," Kevin Loumas of Atlas Copco, which is based in
West Springfield, Mass., says. "The high-reach machines and the
attachments that are available today lend themselves to the needs of
recycling and debris processing. I think it cuts back on the labor
necessary to do a job than a drop ball used years ago," he
adds.
Poul Rosengaard, senior application engineer for Caterpillar Work
Tools, Peoria, Ill, also finds the controlled approach preferable
for safety reasons. "The wrecking ball is a dangerous tool and
very hard to control," he says. When equipped with shears,
sorting and demolition grapples or with multi-processors, Cat's
Ultra High Demolition machines, which are purpose-built,
long-reaching, heavy-duty excavators, allow contractors to precisely
control the demolition process, Rosengaard says.
Tom Witt, director of sales for Breaker Technology Inc. (BTI),
Thornbury, Ont., agrees that demolition attachments mounted on
long-reach excavators provide advantages. "With the long-reach
excavator, you have better ability to control the demolition, which
is especially critical in urban areas."
Michele Carline of Tramac Corp., Parsippany, N.J., says that the
weight of the attachment is an important consideration in high-reach
applications. "The attachment cannot be too heavy, or it may
cause the excavator to tip over." She adds that Tramac's DA
Processors are lighter in weight, making them suitable for use with
long-reach jobs.
With the variety of attachments available, selecting the right
arsenal of attachments can be a daunting task.
GRASPING THE SITUATION
"Today, demolition contractors have a variety of attachment
choices," Carline says. With the number of tasks demolition
contractors confront, that's a good thing.
In addition to demolishing structures, demolition contractors face a
variety of recycling-related tasks, including the primary sizing and
separation of material. This necessitates a number of tools, though
just how many depends on the size and nature of the job and the time
constraints a contractor faces, Cat's Rosengaard says.
Carline says that the most popular attachments include hydraulic
breakers, demolition processors, shears and demolition grapples.
"Each attachment has a unique function that helps the
contractor increase production," she adds.
Kevin Bakke, chairman of Genesis Equipment & Manufacturing,
Superior, Wis., says the versatility of grapples on a demolition
site is often understated, as is their importance to the demolition
contractor. "Our GSD (severe-duty) contractor's grapple is
built to do a lot of actual demolition in terms of ripping and
tearing a structure apart," he says. "It can act almost as
a shear to an extent if the steel is in the realm of the excavator's
breakout force."
The grapple then can be used to pick and sort through the resulting
rubble.
"Grapples have been
the main choice for material handling tasks among recyclers for many
years," Carline says. Their dexterity and ability to handle
large volumes of bulky, inconsistently sized material gives them an
advantage over standard buckets on the demolition site.
"There is normally quite a bit of material sorting done of
C&D, and the sorting requirement is almost certainly increasing
in importance," Rosengaard says. "The mechanical grapple
(contractor's grapple) is much better suited for the sorting task
than a bucket."
Cat also offers a sorting and demolition grapple that offers
360-degree rotation and Faster cycle limes than traditional
contractor's grapples, Rosengaard says. "This tool is widely
used in Europe, where it has replaced the mechanical grapple to a
large extent," he adds.
While grapples are just one tool available to demolition
contractors, smaller contractors may not be able to afford a variety
of dedicated attachments. They may instead opt for multi-processors
or universal processors. These tools feature a primary tool with
three or four interchangeable sets of jaws, allowing the base
attachment to go from a crusher to a pulverizer to a shear,
depending on the particular task at hand.
BREAKING IT DOWN
BTI's Witt says these tools give the smaller processor much more
versatility while also allowing them to keep operational costs down.
"If you are a smaller, independent contractor where the
versatility of your equipment is extremely important and you want to
tackle a job, then the multi-processor offers you a lot of
options," Witt says.
Not only can a demolition contractor save money by purchasing fewer
attachments, he can also scale back the crew needed for the job when
using a multi-processor. "You can eliminate one machine and one
man," Witt says. Some jaws are capable of multi-tasking as
well. For instance, BTI's MS Series Hydraulic Multi-System features
a set of demolition jaws that allow contractors to crack or crush
concrete as well as shear steel.
Carline also finds demolition processors with interchangeable jaws
to be the "workhorse" of the job. "It allows you to
demolish a structure and to recycle the material as required by the
job," she says of Tramac's DA Series processors. The attachment
features "easy-change" jaws that allow it to perform
multiple functions. "The MC jaw is a concrete cracker that can
crush concrete, while the MS jaw will cut the rebar and steel
beams," Carline says.
Atlas Copco offers a multi-processor it calls the Combi Cutter.
"A Combi Cutter is an attachment that allows you to switch
between a cutting jaw for steel and a pulverizing jaw for smashing
bricks or mortar," Loumis says.
Genesis manufactures a similar processor that it calls the DemoPro.
However, it does not require a complete jaw change, which helps
contractors to save time on the job site, the company's Bakke says.
"Our tool is designed with a multi purpose jaw that requires no
change-out," he says. "At most, [operators] can simply
bolt in different concrete pulverizer points, or they can bolt in a
steel piercing tip if they have a steady diet of structural steel to
process."
Bakke says these adjustments can be made in about l0 minutes.
"Jaw change-outs take close to an hour. That is lost time, lost
productivity."
While multi-processors offer versatility and affordability, some
contractors may prefer dedicated tools, which typically enable
contractors to make quicker work of a job.
TEARING IT UP
Witt says he sees more hydraulic pulverizers being used in secondary
demolition. "On sites where they are recycling concrete, there
are a lot of hydraulic pulverizers more so now than before," he
says. "They can do so many things with them and they can take a
lot bigger concrete than they used to with the manual-type
crushers," he adds,
Witt says hydraulic pulverizers can be mounted on smaller
excavators, such as those in the 25 to 30 ton range, though they can
do the work of a mechanical tool mounted to a 100-ton excavator.
The hydraulic pulverizers extra power comes from its piston, which
is powered by the hydraulic circuitry of the excavator. Mechanical
tools, however, use the bucket's cylinder to generate their force.
Atlas Copco's Loumas also finds hydraulics advantageous when
processing concrete with hammers. He says a hydraulic hammer enables
a contractor to process more concrete in a given time frame, while
saving the hammer's carrier some wear.
"On some mechanical units, you are physically picking these
things up and dropping them on the debris," Loumas says.
"You have a more controlled environment with the hydraulic
hammer."
However, if the building contains a lot of structural steel, a shear
is a natural choice for the job.
"If there is a lot of steel, the perfect solution is a steel
cutting shear with 360-degree rotation. It is almost vital to have
that rotation so you can work at every angle," Bakke says.
"A rotating shear sized to the job is priceless."
Thanks to the variety of structures that demolition contractors
encounter and the budding preference for controlled demolition, it
appears that attachments will be a growing part of a demolition
contractor's arsenal.

Komatsu
has extended its “Dantotsu”, or Unrivalled Specification
PC450 Dash 7 Long Carriage excavator model to include the
unrivalled versatility of their High Reach Demolition
specification. With this change, the amenities that have
made their Dash 7 High Reach machines so popular have been
added.
This demolition
machine is now available with a hydraulically variable gauge
undercarriage. The maximum track gauge is 3180mm and the
minimum is 2280mm. This allows the machine to be kept within
a 3000mm transport width, even when outfitted with 700mm
track shoes. It can accommodate 600mm or 700mm track shoes.
With a total machine weight of 58,050kg (or 68,000 kg with
hydraulic undercarriage), it uses Komatsu’s usual Dash 7
specification heavy-duty, low maintenance track shoes.
The machine has
been designed with many user needs in mind. It vastly
improves the adaptability of the PC450-6 high reach
demolition machine, with the addition of Komatsu’s Quick
Release Boom system, featuring internal
hydraulically-powered boom connect pins, quick-release
hydraulic lines, lightweight equipment stands, and
two-position excavation attachment. Because the
PC450LCD-7’s high reach boom has three segments, the
demolition contractor can use one machine all the way from
25000mm maximum height (to arm pin) to ground level; a
second, smaller machine is therefore not needed to complete
ground level demolition of a high-rise building.
This new machine
has an operator selectable hydraulic flow control and
adjustable presets for rapid attachment changes. It also has
additional filters and accumulators for attachments and
machine protection, plus a hydraulic pressure relief
control, automatic changeover valves and attachment piping
options.
The new PC450LCD-7
is designed to deliver excellent durability and reliability.
It’s outfitted with heavy-duty work equipment, and its
major components are all designed and built in accordance
with Komatsu’s stringent quality and performance
specifications. Its electronic devices have been proven to
be exceptionally reliable.
This new demolition
excavator is supplied with Komatsu’s industry-renowned
SpaceCab™ and it’s fully ISO10262 level 2 FOPS
certified. This cabin, tilting between 0 and 30 degrees,
with its spacious interior and ergonomic amenities, provides
a working environment that supports the highest levels of
operator comfort and ease of use. Its high capacity air
conditioning system also pressurizes the sealed cab, helping
to create an environment that’s dust free. The cab’s
damper mounts ensure low vibration levels.
Its turbocharged,
246kW / 330 HP air-to-air after-cooled Komatsu engine meets
all Stage II emissions standards without any sacrifice of
power or machine productivity. In economy mode, the engine
delivers superb fuel economy.
