firms off guard. Export markets continue to
be added – new BAV dealers were signed last
year and more have already been signed this
year – but the stronger sterling is not helping.
Dealers in the USA and Russia were not as
busy as in previous years. Our most successful
new market last year was Norway.”
This demand has had a knock on effect
for BAV in terms of where its R&D effort
is concerned. Marcus went on: “Customer
requirements trump both R&D and stock
orders! At the present time, we’re running
with a minimum of 4 weeks work ahead.
On larger and more complex attachments,
it’s more like 5 to 6 weeks, so even building
stock of the existing range is not possible.
First priority are the dealer’s and customer’s
requirements, then we’re looking to augment
our own stock levels before we get the next
Working to a deadline
The Colorado Department of Transport opted for an Accelerated Bridge Construction
when carrying out improvements to Denver’s Pecos Street bridge at the Interstate 70
Interchange. The plan was to bring the bridge down and the road re-opened to traffic
at 7.00 am on the Saturday. Since the road could not be closed until 22.00 pm on the
Friday evening, that left just eight hours for the job to be completed. A replacement span
was constructed close to the site of the existing structure that was to be moved into
place once the existing span was removed.
To bring down the original bridge structure, Performance Equipment based in Erie,
Colorado, supplied four Atlas Copco breakers together with two Atlas Copco CC 3300
Combi Cutters. Before demolition of structure could begin however, the crews had to
construct a level path for the tracked carriers of the replacement span using earth
and steel plates, a task that took four hours, leaving just four for the demolition of the
reinforced concrete structure of the span.
Working from the centre out on both sides, each CC 3300 was paired with two
breakers, with the latter breaking up the concrete structure, with the former cutting the
steel reinforcement as it was exposed by each of the hammers. Despite just having four
hours to complete the job, the replacement span was moved into position according to
plan and the new Pecos Street bridge re-opened to traffic on schedule.
project off the CAD systems and into the
metal for testing. We have a complete new line
to add into the existing three line set-up of
jaw crushers, crusher buckets and screening
buckets, but for now it has to remain under
wraps."
Josef Martin GmbH told D&Ri that
it has seen a strong start to 2014 with a
definite upturn in market activity hinting,
the company says, that a full recovery is
under way. Sales throughout Europe and in
particular Austria, Germany and Switzerland
are on the increase and it views the rest of the
year with confidence. Martin also said that
it has recently made a demolition grapple
available for machines up to 28 tonnes in
weight.
DEVELOPING ATTACHMENTS
Allied Gator offers a patent-pending Serrated
Gator blade that is now available as an
option on new MT mobile shears and can
also be used with any of the 11 existing MT
shear models, irrespective of size, with no
modifications being required to the shear.
According to the company, the new blades
have a service life that is up to 50% longer
than traditional shear blades when processing
general scrap and up to 90% longer when used
to cut steel wire and cable. They can also be
used effectively to process difficult materials
such as stainless steel and thin sheeting.
Allied-Gator sales and marketing manager
Mike Ramun said: “The serrations of the MT’s
new blades are designed to progressively pass
through material like a saw blade rather than
forcing the shear to chop through a large mass
of material like an axe.
This new blade design does not rely solely
on sharp shear blade edges to achieve the
cut. Instead of a snipping effect, these blades
generate a tearing action. This allows the MT
shear to grip and tear scrap materials, which
is a far more efficient cutting method than
the traditional ‘scissoring effect’ utilised by all
other mobile shear blades.”
As the shear jaws close on structural steel,
Atlas Copco has introduced two new
