Rusch
takes High Reach Demolition to a higher level.
It
was January 2006 that Beelen Sloopwerken
BV. officially
announced that it had ordered Europe's largest Demolition
Rig. The machine base was a 85ton Cat 385CL modified by Caterpillar dealer Pon
Equipment. Pon then asked Rusch
Crane Repair to modify it to a Extreme High Reach
Demolition machine.
For Rusch this was their first time to do a High Reach
Demolition conversion. The company was specialized in Crane
repair, so it had some experience in high strength booms,
but had not used this, or any other technique, on an
excavator.
Ruud Schreijer from Rusch said:
In the beginning the base machine was much bigger, but due
to transportation limits and delivery-times and warranty-problems,
they eventually came to us asking the question were all other
boom manufactures said: "It could not be done!" If
we could do a Extreme High Reach Package on a relatively
small base machine, like the Cat 385CL.
After many calculations we found a solution that would
tackle this problem. A conventional boom was out of the
question. Calculations told us 45mtr. would be the maximum,
with a medium tool (2-3ton). But if we used a special high strength
steel, like used on some cranes, and make it telescopic, we
could reach around 60mtr. This type of steel is very light
and stronger than many other steel types used for boom conversions.
We had a lot of experience with this product and knew its
potentials. We are one of the few companies that are capable
of repairing crane booms made of this product. It requires a
special treatment. Bending and welding it, can not be done
using normal techniques. One of them is that it takes some
chemicals to retain its properties.
We made a three section 60mtr. (197ft) telescopic demolition
boom, 6mtr. hydraulic undercarriage, and did the upper-carriage
conversions like the extra counterweight, extra tank, etc.

We eventually decided not to do the automatic extending
counterweight-system, seen in the animation.
The machine has now worked for more than a year. We have learned a
lot, did a lot of
A modifications, and we can say, where everyone said;
It wouldn't work, we proved them wrong, and we know now how
to build them."
A few months later Euro Demolition and Rush were sitting
around the table talking about a new very challenging
project: "To build an even higher machine."
Euro Demolition and Rusch go way back, as Rusch was their
main partner for maintenance of Euro's crawler cranes. With
the now-how from the Cat 385C 60TUHD and the expertise of
Euro Demolition they started up a task force to investigate
if this was possible and how.
It was only a couple of months after the Cat 385C 60TUHD
erected it's arm for the first time that Euro and Rusch
signed an agreement to build the Highest High Reach
Demolition excavator in the world.

From
quarry digger to demolition excavator.
In was
the first week of august that 'Steffi' left its two brother
Cat 5110B's 'Nina' and 'Antonio' in a quarry base in Germay.
Seffi' also a Cat 5110B was bought by Euro
Machinery and was rented by Euro Demolition to tackle
some very heavy foundations at the Grolsch-brewery
demolition jobsite in Enschede, The Netherlands.
The machine performed so well that Euro Demolition decided
to keep the machine.
Four months later the machine was working at another demolition job
in Groenlo, The Netherlands when it was accompanied by
'Nina'.
This machine was again brought in by Euro Machinery.
And, Yes again Euro Demolition decided it was the right
machine for their machine list. Especially because it had decided
that 'Steffi' was going to be transformed to a special
Triple HRD version and they were still working on the
"Highest HRD project" and this looked like the
right base machine for it.
The official announcement:
Next
year the high reach demolition excavator sector will see a
new record-breaker, when a three year old Cat 5110B (delivered
by Euro Machinery) will be modified by Rusch Special
Products. The machine owned by Euro Demolition will be 90m
(295 ft) high.
This is 25 m (82 ft) taller than the current
record holder, Kobelco's SK3500D owned by Nabekai in Japan.
Very impressive is the weight of the tool that will go on
the end. Most Extreme High Reach machines currently
available, can only carry a 2 or 2.5 ton tool. The new
machine will carry 5 tons to full height and a 12 ton tool
to 80m (262 ft)!
This base 5110B will be heavily modified to carry its giant
boom, with additional counterweighing, a lengthened and
widened undercarriage and additional hydraulics.
(total
expected weight 250tons)
Today
was a special moment. The Cat 5110B has done its last hours
as a normal Cat 5110B digging excavator. The machine performed
well these last months as a big muscle wrecking machine,
playing with large foundations and big steel buildings. Now
it is time to leave this work behind. As for the coming
months this machine will be world news.
Today it started its journey to become the worlds highest
demolition excavator in the world.
It was late in the afternoon that we saw how the machine was
taken apart at its last jobsite in Dinslaken, Germany and
transported to the Rusch headcounters in Zwaag.
A very special day also, because it was also the day that
its big brother the Cat 5110B Triple also owned by Euro
Demolition, made its first moves. Its first job; helping to
take its brother apart.
HRD
Exclusive Today we were asked
to follow the building process of the Cat 5110B 90TUHD. In the next
couple of months we will follow the machine in its transformation
process and keep you updated with the latest developments.

First
visit Today we traveled to
Zwaag (NL) for the first time to see the conversion progress.
The undercarriage conversion is ready, and beside the counterweight
and tank modifications the construction work on the upper carriage
is also ready. Construction work now is focused on the 90 meter
boom.

For
the first time to the paint shop Today the machine was
transported to the paint shop from Euro Machinery in Harderberg.
Only the inside will be painted, the outside is done when the
machine is completely finished.

Welding... Today we visited the machine
for the third time. The painted base machine is waiting.
The tracks and extensions have been filled up, and the tank is
finished.
In the coming weeks the Rusch people will focus on completing the welding
of the boom sections and sticks.
At the end of this month they want to start building up the boom and
base.
Then the next crew can start building the hydraulics, and the
welding people can go on the next 5110B project for Euro Demolition;
the second 5110B Triple, followed by the 75m E-HRD.
We added numbers on the pictures, to make it easier to understand
the progress and see what section comes were.
