Processing concrete, milling
concrete, producing cold mix, paving
and compacting a hydraulically bound
base layer, creating concrete profiles
– the second demonstration focused
on linking these technologies. From
Kleemann’s brand-new Mobirex MR 110
Z EVO mobile impact crusher with metal
separator, the crushed demolished
concrete was directly fed into a Wirtgen
KMA 220 cold recycling mixing plant
which used it to produce material for a
hydraulically bound base layer. Paving
was carried out by the Vögele Super
3000-2 paver, and the paved layer was
then compacted by the latest generation
of Hamm tandem rollers and pneumatictyred
rollers. During the final stage of the
demonstration, Wirtgen presented the
new SP 15 slipform paver which paved a
concrete profile in a live operation.
Hands-on technologies in
theory and practice
After the end of the live demonstrations,
the visitors poured onto the site to have
a closer look at the layers, milling cuts
and construction materials produced by
the various machines. The great variety
of technologies and products offered
new information and insight gains for
everyone present. “We are milling contractors, and so
our focus is mainly on the milling machines. All the same,
the demonstrations of crushers, pavers and rollers are
of great interest to us as they enable us to learn more
about the innovations in the preceding and following
project phases,” declared visitors from Sweden. Not
so for a contractor from Colombia. He has worked
with a wide variety of Wirtgen Group technologies for
many years and was particularly interested in the large
Vögele paver and feeder models. A German quarry
operator expressed his major benefits as follows: “The
live demonstrations were very impressive. They have
reinforced my trust in the brands and products of the
Wirtgen Group because I could see for myself that the
machines do in fact perform as promised.”

The audience followed the expert lectures given by Kleemann
specialists Markus Balkenhol, Thomas Mössner and Otto
Blessing in the new production building with great interest.
The assembly station of the 400-ton Mobicat MC 160 mobile jaw
crusher was undoubtedly one of the main attractions during the
visitors’ tour of the new Kleemann plant.
Three Kleemann specialists presented the latest
products and projects in a series of highly interesting
expert lectures. They conveyed a clear message:
Kleemann will work out tailor-made and economical
solutions for each project in close cooperation with
the customer. Separate short presentations held
in the outdoor area additionally enabled visitors to
discover the outstanding features of the latest Wirtgen,
Vögele, Hamm and Kleemann machines. The sound
professional explanations given were just as convincing
as the live machine demonstrations the customers had
witnessed.
