The factory hall with the other cranes

Preparations are under way
in the same hall in which both double-
girder bridge cranes are used.
the most important among all large-scale
machines is the vertical lathe and milling
machine which was designed and built for
siempelkamp by schiess GmbH in Aschersleben.
this large machining center is one
of the most extraordinary of the past
decades: the Vertimaster VMe 10 singlecolumn
machine machines mill heads,
grinding plates, and grinding tables as
well as components for the wind power
industry. Component parts with weights
of up to 400 t (441 Us tons) and heights
of up to 6 m (20 ft) can fit on the faceplate,
which can be extended with the
help of beams mounted to the faceplate in
a star-shaped arrangement, thus resulting
in a machining diameter of up to 16 m
(52 ft).
the production capacity in Krefeld was
expanded by 3,000 m² in order to accommodate
the vertical lathe and milling
machine. A third double-girder bridge
crane became urgently necessary. “With
the new crane we are able to operate the
turning lathe, and thus minimize expensive
waiting periods for a crane. the parallel
setting up of large parts results in a clear
efficiency increase during production,”
describes Michael Kubbe.
