THEME
tower sections with a large diameter and the Super Wing Carrier is the
standard trailer for the transport of ultra-long rotor blades measuring
up to 80 metres. For the cranes that are used for the construction
of windmills Nooteboom also delivers the most efficient transport
solutions, such as the Teletrailer, Ballast trailer and the Manoovr.
Nooteboom keeps a close eye on the developments in the wind
industry. The Nooteboom policy is to provide - in addition to user
friendliness and safety - a lower total-cost-of-ownership (TCO).
Wind energy has become a stable
factor in our energy provision
THE GOOD NEWS
The good news is that the construction of windmills worldwide is
advancing well, but at the same time the solutions for the transport
and storage of the energy are still in its infancy. If the technology
for the production of hydrogen gas improves, the future wind parks
will move to thinly-populated regions with strong winds. In a short
space of time large wind parks have been built within Europe, but
the electricity network has not been adapted yet to distribute the
fluctuating production of the wind parks across Europe. Wind energy
has become a stable factor in our energy provision, with a cost price
that can compete with gas or coal-fired plants. In order to achieve that
competitive price all the suppliers that are involved in the construction
and transport are required to work even more efficiently. They can
count on Nooteboom, because they have been working for years
already on extremely efficient solutions for the transport of wind
turbines. ■
CLIMBING CRANES
Wind mills are getting taller all the time and a generator with
a weight of over 100 tonnes is no longer the exception. Most
windmills are built with conventional cranes. Giant cranes, such
as the Liebherr LTM 11200-9.1 mobile crane and the Terex CC
8800-1 crawler crane are used to build the biggest wind turbines.
A lot of space is needed to erect these huge cranes and dozens of
heavy transport
combinations are required to move the cranes to another building
site. On several fronts work is underway to develop crane concepts
that need less space and are more efficient to transport. The new
cranes must also be able to operate in stronger winds. Various
concepts only exist on paper, but two of them are already in use:
the Krøll K1650L tower crane is tailor-made for the construction
of very tall windmills and to work in higher wind speeds. Dutch
company Lagerwey goes one step further with the Climbing
Crane. This Climbing Crane was first tested in the autumn of
2017 when they build a Lagerwey L136 wind turbine near the
Eemshaven (NL). The complete Climbing Crane is transported on
just three vehicles. The development of climbing cranes is still in
full swing. Mammoet – the WTA 250 – is working on a version
where a guide rail is attached to the tower first. The Climbing
Crane of Lagerwey is attached to the tower without a guide rail.
