UK’s
biggest excavator-based demolition machine
UK’s
largest excavator-based machine, incorporating a 50-meter working
pin height will be used to demolish the ancient Norfolk and Norwich
hospital
The monster demolition machine has just been put into operation by
the contracted National Federation of Demolition Contractors (NFDC)
member-company 777
Demolition and Haulage Limited. It was recently purchased from HM
Plant, who is the sole distributor of Hitachi construction
equipment in the UK.
The decision to purchase the huge machine was based on the Kocurek
design. It was necessary for the machine to be modified. Kocurek
Excavators Ltd. carried out the essential work. The machine, a
Hitachi EX1200-5C, has an operating weight of 130 tones and is
fitted with 50-meter “Ultra High Reach” demolition equipment.
The telescopic section can be fully extended in less than three
minutes from a working pin height of 32 to 50 meters.
Although the imposing machine matches the largest working unit
already in existence – a more expensive 170-tonne crane-based
machine incorporating fixed extensions – Kocurek opted for a
design with a compact telescopic boom, which allows the use of a
smaller base machine, resulting in considerably reduced capital
outlay. The comprehensive single-rigging package also eliminates the
time-consuming need to remove and store fixed sections that are
capable of reaching different working heights.
One of the impending tasks for the excavator, once delivered to the
client, will be the demolition of the old Norfolk and Norwich
hospital. Due to the brief received for the contract, 777 required a
machine that would be suitable in order for them to tender. The
machine, which was modified specifically with this contract in mind,
will demolish the site’s two tower blocks to make way for a new
housing development.
Sales Director of Kocurek Ron Callan, is delighted to have had the
heavy responsibility of producing the record-breaking machine:
“When we entered preliminary discussions with HM Plant and 777,
the initial plan was an 80-tonne base unit to carry 40-meter
“Ultra High Reach” Demolition Equipment. Over time this grew and
the specification for the EX1200-5C was agreed. Working closely with
the customer and HM Plant we have achieved our joint goal and
Kocurek is extremely pleased with the result.”
Managing
Director of 777 Michael Pearce said: “We are very pleased with the
relationship and proactive attitude of Kocurek. We needed to get
details of the machine finalized in order to tender for the contract
in Norwich. Without the advice and support from HM Plant and Kocurek, we wouldn’t have been able to achieve this. It has been a
fantastic, challenging project… and I am delighted with the
finished product.”
Peter O’Malley, Sales
executive of HM Plant, echoed the above: “777 Demolition and
Haulage is a well established company and we are pleased that they
chose HM Plant for their purchase. HM Plant’s extensive knowledge
of the industry, coupled with the reliability and performance of the
precision-manufactured Zaxis machines, allowed all objectives to be
met successfully. The EX1200-5C is an ideal unit for demolition and
dismantling projects. The modifications… by Kocurek will allow 777
to adhere to all their contract requirements. We look forward to
working with those involved in this exciting project in the
future.’’

Rumors
about very high HRD excavator The Italy based
boom-manufacturer CMO2
is still leading the HRD height records. With the construction of
the 55mtr. HRD excavator for Despe,
(which we still haven't seen in action) and the PMI 980 with 50mtr.
HRD-boom, they produced the impossible. To stay ahead of the
competition they now are building an even higher custom build HRD
excavator. Rumors spread say it will be well above 65mtr. Even
heights of 83mtr. are being told.
We will wait and see.

Volvo's
new B-series... Following on
from the launch of the Volvo B-series excavators at the beginning of
this year, Volvo Construction Equipment now offers their EC290B,
EC360B and EC460B models with modular equipment systems (Kocurek).
This can enable them to be changed from standard to high reach 3-
piece demolition equipment configuration.
When rigged for demolition duties with the three-piece high reach
configuration on the EC460B, maximum pin height is 26 meters and
forward reach is 14mtr. The machine can operate safely 30
degree’s left and right of centerline over the front of the
undercarriage allowing attachments with a maximum weight of 2500kg
to be deployed. The machine also features a full dust suppression
system, hose rupture valves and a Prolec Total Moment Indicator. To
protect the underside of the superstructure, additional 12mm belly
plates have been fitted and the additional counterweight weighs in
at 5500kg, which gives an operating weight of 54.6 tones without
attachment.
The maximum pin heights
for the EC290B and EC360B are 17m and 20m with operating weights
increased to 35.6 tones and 45.0 tones respectively, without
attachment.
The operator cab has also been extensively modified on all models.
The seat now tilts hydraulically and to give excellent upward
visibility the cab has a three quarter glazed roof complete with
wiper. A full demolition guard is fitted. The B-series cab includes
features that enhance operator comfort and convenience.
Ergonomically designed, the seat and joystick control consoles can
be adjusted independently to conform to individual operators
requirements. The cab also has an electronic climate control (ECC)
as standard.
An expanded window area without crossbar and with larger window
wiping area with parallel working wipers means the B-series
excavators have improved visibility and operating safety.
Additional features include shock reducing mounts and
sound-absorbing material for minimal noise and shock levels; an
additional rear-view mirror with a extended viewing area; operator
friendly instrument panel; and extra storage behind the seat and
more leg room. The new over-pressurized cab and highly efficient
ventilation system also provides a more comfortable and cleaner
operating environment.

Demolition
of Administrative multistoried building C 660 Free space for developing new center in the industrial park
Höchst
The demolition of the former
Administrative multistory building C 660 is one of the largest
demolition projects in Germany at this moment. The first new
buildings at the new, trailblazing future project for the industrial
estate, should be finished at the end of 2005, demolition should be
finished at the end of 2003.
The project is led by Infraserv,and demolition contractor Laubscher
GmbH is asked to bring down the 54 meters high C 660 building.
The highest floors are being demolished using the top-down method.
Small excavators together with bobcats and taking down 3 floors.
Together with a crane to take down large pieces to reduce possible
large vibrations.
One of the companies HRD excavators is then used to take down the
next floors.
This Cat 5080 UHD excavator reaches 43 meters high and will eat down
the multistory building. For the minimization of dust the High Reach
Demolition excavator is equipped with water nozzles, which strike
down resulting dust immediately.
C 660 will altogether leave approximately 26,000 tons of building
debris. Approximately 80 percent of it can be recycled. This is
20,000 tons of clean, re-usable building material.

Exploding
job for Hofstede-Groep After a Gas explosion the Hofstede-group
was called in to take out the blown away section and stabilize the
surrounded sections of a 5-story apartment building. Before
beginning with the actual demolition, the blown-away section was
secured to search for the cause of this major explosion.
Hofstede was called in an hour after the actual explosion, and
brought in their special equipment. One of them is the Hitachi
EX400LC-2 High Reach Demolition excavator.
"This tool is the safest demolition method. Everything is at
point of collapsing, so eating small pieces from a save distance is
the only way to do this job." According to a spokesman from the
company.

Large
scale Demolition in Maastricht (The Netherlands) The historic city center of
Maastricht is undergoing major demolition-action. One of the largest
projects, is the demolition of the old State buildings. Sagro, one
of the Netherlands biggest demolition contractors, is chosen as
contractor to do the job. It has several pieces of equipment at the
site. One of them is the Hitachi EX550LCH with it's Verachtert
3-piece High Reach Demolition boom. The machine is capable of
reaching 27mtr. above ground level.
A spokesman said; "It's a mean Demolition Machine". The
machine was brought in because of the height of these buildings. Due
to the many safety regulations balling is in these cases no option.
The many stores and market are making this site a very popular
public area. The church and other old buildings near the demolition
site are another problem. Dust and seismic activity therefore had to
be reduced to almost zero. More pictures in HRD

Controlled
Demolition Group in city centre demolition Controlled Demolition Group found
themselves in a series of 'tight spots' during their demolition work
on the 800,000 sq ft Central shopping center development – but
none of them posed a problem.
The £1.5 million contract involved demolishing a former C&A
store, a multi-story car park and the Mecca Bingo Hall beneath it,
as well as demolishing adjacent shops and the dismantling of a
pedestrian footbridge – all just meters away from Croydon's
tramway and bus routes.
Controlled Demolition Group employed a wide range of demolition
techniques to complete the contract with minimum disruption to the
public and transport systems.
Operatives worked painstakingly by hand, using hand tools and small
machines, to demolish the top two stores of the car park while bingo
sessions and parking continued undisturbed beneath.
And the firm's custom-made 105 ton super long reach machine, plus a
whole arsenal of smaller long reach machines, were brought in to
demolish huge sections of the structure swiftly, safely and with
minimum disruption to the public. Source: Controlled

First
job for Cat 330C UHD Dutch demolition contractor Vermeulen BV. ,as mentioned
earlier, bought one of Caterpillar's new Ultra High Demolition
machines; the Cat 330C UHD.
Time for us to go out and see what this machine is capable of.
The first job for this 330C UHD is the demolition of an old military
site in the center of Middelburg.
The highest building at the site is only 17mtr. high, so it is a
piece of cake for this 21mtr. machine. It also picks up large pieces
of steel at ground level. A very well balanced machine, with great
reach at ground level as well as in height.
