Große Turmdrehkrane

21. März 2010

From a Lebus document: In fact, Lebus supplies drums for all cranes built by
Krøll, a Danish manufacturer that is part of the
Favelle Favco group.
The K-10000 lifts 240 tonnes out to a radius of 44m
and at the end of its 100 metre jib it can lift 94 tonnes.
At 10,000 tonne metre rated capacity, there is no other
crane like it. On top sits an auxiliary crane just to
service the big crane. This 400 tonne metre Liebherr
(also Lebus drums) is as big as anything you are
likely to see working downtown. Line pull on the
K-10000?s winch is 10,000kg. The drum is 1809mm
between the flanges and 1500mm in diameter. It
carries 30mm diameter wire rope in four layers.
The crane was designed for nuclear power station
construction in the 1970s. Only 15 units were ever built.
The first unit went to the USA but after the Three Mile
Island nuclear accident in 1979, a second order was
cancelled and it remained in Denmark. The other 13
units all went to the Soviet Union, with the last one
delivered in 1986. However, only five were ever erected
before the Chernobyl accident put an end to the Soviet
nuclear construction programme.
In post-Soviet times, some of these units have
re-emerged and K-10000s can be found at work today
in Singapore, Norway and China. The photo shows one
owned by Mammoet of the Netherlands working in
Owensville, Indiana, USA in 2001. Note how small the
motor car looks at the very bottom of the picture!
