ALLU bucket gets its teeth
into ATG Group projects
ItÕs the only bucket on the market that will do the job Ð thatÕs what the ATG Group think
of the SMH from ALLU, having tried every other alternative they could find.
ATG Group's new ALLU SMH
The Coleraine headquartered
company provide a broad
customer base with
environmental and waste
solutions, including remediation
of contaminated land and
the treatment and disposal
of Japanese Knotweed.
Up until recently they hired in
ALLU buckets, but because
they were so impressed
with its performance, they
opted to purchase an SMH
3-12, used specifically in
difficult areas that other
buckets couldn’t cope with.
Comments ALLU UK Director
David MacLynn: “The SMH is
designed for the continuous
processing of difficult, heavy
and wearing materials and for
job sites where the processed
volumes are especially large.
With two hydraulic motors,
the SMH models can utilise
approximately double the power
compared to the basic model.”
And that was a big attraction for
ATG. Explains ATG’s Contracts
Manager James Stewart: “We
found that ALLU was the only
manufacturer of a bucket that
was capable of handling our
type of work, its large teeth
easily chews up heavy clay
that is so prevalent in Northern
Ireland. More often than not we
34 Plant & Civil EnginEER
find ourselves working on rain
sodden terrain and there is no
other bucket that we could find
on the market that could work
in such heavy conditions.”
And he added: “The bucket
is very robust and performs
exceptionally well. In fact, we
have found that we can turn
around jobs much quicker
with this bucket, allowing us
to take on more work and, of
course, it means the customer
is getting a more efficient and
cost effective service, so it is a
win-win situation all round.”
The SMH offers different
blade and drum options that
are designed so they can be
easily changed, even in field
conditions. This feature also
improves the productivity of
the bucket, because it does
not need to be transported to a
workshop for alteration work.
There are four different types
of standard drums available.
In addition, various types of
special drums are available.
Selecting the right type of drum
is the first step in adapting the
bucket for specific materials.
There are eight different
types of blades available. It is
extremely important to use right
blades for different materials.
The use of correct blade type
improves the quality of the
end product, reduces wear
and increases the capacity
of the Screener Crusher.
“The support and service we get
from ALLU is also very important
to us, and because they have
locally based representation in
Northern Ireland it gives us the
confidence and peace of mind
that if anything does go amiss,
assistance is only a phone
call away. Indeed, occasionally
we do have to ring for advice
and guidance and in David
MacLynn we have a contact that
is well versed in the product
range and its capabilities.”
Japanese
Knotweed
One of the company’s latest
projects was on an old industrial
site in Bangor where they were
responsible for the removal of
not only Japanese Knotweed,
but non-hazardous materials,
inert soil/rubble, tanks, asbestos
& hazardous materials, with the
ALLU bucket taking the task of
breaking down the contaminated
materials in its stride.
During the redevelopment of
the site, Japanese Knotweed
from the adjoining site had
been inadvertently spread onto
the Client’s site. The Knotweed
was located within the critical
path of the development
programme – therefore a
rapid solution was required.
EradZion8 technology was
utilised on the areas of the
site which were critical to the
development programme. In-situ
Eradicate technology was then
used to spray and remove the
Knotweed and a root barrier on
the site boundary was installed
to prevent any re-infestation.
ATG have continued with
an ongoing commitment
to manage and treat any
Japanese Knotweed growing
on the neighbouring site.
Hazardous
All contaminated soil
discovered on the site was
also transported to a licensed
landfill facility in England
for disposal. Contamination
identified included heavy metals,
hydrocarbons and asbestos.
The remaining soils were tested,
treated and reclassified to allow
the materials to be land-filled
locally at a licensed facility. The
ground water on site, which
was contaminated, was treated
via a mobile purpose built oil
water separator and specialist
oil removal media. Additionally
a cut off wall was installed
to ensure that contamination
from adjacent sites could
not migrate into the site.
Inert
The brief given to ATG Group
was to divert excavated material
from landfill, so they looked
at bringing the best available
technology to the project. Their
approach was to undertake a
full examination of all reports
and findings and agree a
strategy to deal with the material
requiring removal. The Inert
materials were recycled where
possible and the remaining
used as fill under an NIEA
exemption at another site.
Abandoned underground
storage tanks were also
unearthed on the site; these
were degassed, dewatered and
removed, with the surrounding
groundwater being monitored
during the process. Some
of the groundwater was so
heavily contaminated that it
had to be removed off site by
vacuum tanker for treatment
at a specialised facility.
Non-Hazardous
Additionally, through a planned
programme of excavation,
testing, segregation and
appropriate disposal, a total
of approximately 1,600 cubic
metres of non-hazardous
contaminated material
was removed from site to
suitable treatment facilities,
with a full paper trail which
covered all the necessary
legislator requirements for
transportation and disposal
of contaminated material.
Throughout the project, ATG took
responsibility for analysing and
identifying the correct category
for any waste being generated.
They ensured full compliance
with the Duty of Care regulations
on Transport, Disposal and
Environmental issues. All of
this was achieved on time and
to the budget agreed on with
a major local contractor.
