Carlsberg tanks are
moved to Fredericia
A lot of power was required when 12 tanks of 31 ton
each were lifted from Carlsberg’s facilities in Valby and
onto steel frames on the ground. A 450 ton and 200 ton
crane were needed.
Moving 12 tanks from Valby to Fredericia requires planning and resources.
And especially resources in the form
of power, as each tank has a diameter of 8 m, is nearly 17 m high and
weighs more than 30 ton. When full,
a tank like this contains 2.5 million
bottles of beer. The first challenge
was to lift the empty tanks from their
original location and onto a frame
structure on which they were transported to the port of Copenhagen
and further on to Fredericia by barge.
Two cranes solved this first part of
the task superbly. In two days, the
12 tanks were lifted onto their frame
structures and ready to begin their
journey to East Jutland. A total of 36
tanks will be moved to Fredericia, and
Krangården is in charge of the turnkey project, which includes lifting the
tanks in both Valby and Fredericia,
arranging transportation in both cities
and also sea transport by barge.
Heavy lift at “DR Byen”
The most spectacular event on the construction site of the
Danish Radio new media building “DR Byen”. This is how
DR described the erection of the passageway “Indre Gade”
linking the buildings of “DR Byen” at second floor level
above a water channel.
It took five cranes – including the
three largest ones in Denmark
– to lift the enormous steel
construction for this project.
Almost one and a half years
of planning came to fruition
when part of the 190 m long
roof over “Indre Gade” was
installed 30 m above ground
level. The large roof construction made of steel
was lifted in two sections
onto supports with help
from the three largest
cranes in Denmark. The
first section, which was
66 m long and weighed 196 ton,
was lifted 30 m above ground
level using two cranes. The third
crane hooked to a lifting yoke
in the air, after which the three
cranes jointly were able to turn
the roof construction into place.
Another two cranes were used to
counterbalance the torsion of the
construction due to the chosen
method of lifting when the bridge
was placed onto the supporting
For this task we won second
prize for best European Crane
job of the Year in 2007.
Cranes prevent
When parts of the roof on Siemens
Arena in Ballerup collapsed one
cold day in January, rapid support
to prevent further collapse was
As a result, we were hired to bring
cranes to secure the roof while
support work was carried out. There
was an imminent danger of a total
collapse when the roof on Siemens
Arena in Ballerup suddenly started to
collapse. A solution had to be found
to secure the roof while scaffolds
were being built beneath the roof construction. We were hired to solve the
task and found the number of cranes
necessary for the project to succeed.
Supports was placed beneath two
trusses at a time, which meant that
the cranes were constantly moved in
order to be ready for the next area.
The cranes had to be partially disassembled in order to be moved which
required time, planning, timing and
precision. Therefore, AutoCAD planning became an essential tool during
the process. The project succeeded
and the roof was prevented from
further collapse.
New cutterhead ready at
the Hallandsås-project
Space was cramped when
we lifted and placed a new
200 ton cutterhead in the
rock of the Hallandsås
tunnel project.
However, the tunnel boring machine
is again thundering along the 8.6 km
stretch which is part of the new railway connection between Malmö and
Gothenburg. After many kilometres
of faithful service through the rocks in
Hallandsås, the old cutterhead was
ready to be replaced. And we were
asked to solve the task of lifting the
new into place. A great challenge as
the new 180 ton cutterhead section
had to be moved and lifted within an
area underground which only allowed
very few centimetres of workspace.
Four hydraulic gantries operated by
remote control became the solution
to this task. With a total capacity of
1,000 ton, these gantries installed the
cutterhead in place. Ready to take on
the hard work through the rocks.

A 193 ton pedestrian bridge
greets the many people
who every day drive along
the street of Ågade in
With its beautiful design, the bridge
appears as a new city gate to
Copenhagen. However, the design
and construction of the bridge, not
to mention the logistics on one of the
most congested roads in Denmark,
made this lifting task unique. The closure of Ågade for traffic for two days
during Easter, 400 steel plates as surface protection, four cranes and four
hydraulic gantries were the primary
ingredients of this cocktail with which
the Ågade bridge was lifted and put in
place as planned.
The arch of the bridge was lifted from
horizontal to vertical position, pivoted
180 degrees and then finally mounted
at an angle of 45 degrees on to the
foundation beneath the bridge deck.
12 hours before the deadline, the
project was completed far better than
the permitted tolerances called for.
The land of
many bridges
For many years, we have
been the leading contractor
and partner when moving
and lowering bridges above
roads and railways.

We always apply the most modern
hydraulic control equipment thus
ensuring that the beautiful constructions are not damaged during moving,
lifting and lowering tasks. The bridge
decks of many bridges above existing roads are cast in excess height
to allow room for formwork and we
have the expertise to lower the bridge

railway bridges are often built next to
the railway in order to avoid obstruction of train traffic for an extended
period of time. One reason why this
is possible is our specially developed
method of pushing the bridge in place
by lifting the bridge deck, piers and
