Recycling GmbH Lahnau was founded in 1998 and has a direct
interest in two basalt quarries, a clay and quartz sand quarry.
The company also operates its own earth deposit and
construction waste dump, plus three construction waste
recycling plants in the region of central Hesse. The most
important part of the company’s activities is quarrying work to
customer specifications.
“When I joined the company 13 years ago, there were 11 of us.
Today, the company has more than 70 employees actively working
in commercial operations. This development certainly has a lot
to do with our broad range of services,” explains Ralph Lang,
technical manager and director. “We offer all services related to
the quarrying process under a single umbrella.” The company
looks after moving spoils and earth, and has its own authorised
blasting expert. Quarrying raw materials is also possible without
explosives using hydraulic hammers. From releasing to loading
to transporting, Recycling GmbH Lahnau is able to perform all
surface quarrying operations. Manufacturing of end products
with mobile crushers and sieves, plus decontamination and
renaturalisation of surface quarrying sites, are also part of the
services available.
On average, the quarrying specialists at Recycling Lahnau are
in action at around 20 different locations. One of the largest
construction sites at the moment is the quarrying of limestone
for Rheinkalk GmbH in Dornap near Wuppertal. Between the
spoil and the actual limestone, there is a so-called cleaning cut
containing some relatively good limestone, which has to be sieved
before it can be prepared in order to clean out the impurities.
The resulting stone material is then used to produce mineral
mixtures. In Dornap, the company provides all machines and
staff. Twelve earthmoving machines, including four excavators
and three wheel loaders from Liebherr, are in operation here. In
addition, there is also a mobile hammer crusher, a mobile impact
mill with integrated sieve unit, and a coarse sieving machine.
In total, there are 75 large, modern machines. These include
crawler excavators with an operating weight of 25 to 90 tonnes,
rigid-frame dumper trucks with between 40 and 65 tonnes
payloads, articulated trucks in the 30-, 35-, 40- and 50-tonnes
classes, crawlers for various operations, in-hole and outer hammer
drilling rigs for various borehole diameters, wheel loaders of all
sizes, mobile crushers, sieve systems and hydraulic hammers.
48 machines bear the Liebherr name, among them are 15 wheel
loaders, 15 crawler excavators eight crawlers, nine articulated trucks
and a wheeled excavator. “The quality and resilience of the Liebherr
machines are right, and that is especially important for us,” says
Ralph Lang. “We also only hear positive feedback from the drivers:
good hand ling, good performance, plenty of space and comfort in
the cab. We even have excavator drivers who state categorically
that they don’t want any other brand.”
Another decisive criterion for the use of so many Liebherr
machines is flexibility. “As a service provider, we have to be able
to respond extremely flexibly to customer wishes, and to make
enough of the right machines available for a certain period of
time,” explains Ralph Lang. “Where the next job is and exactly
what is to be done is always decided anew, sometimes on very
short notice. Liebherr, and in particular, the rental service of
Liebherr-Mietpartner GmbH give us exactly the flexibility we need.
We have been collaborating successfully since 2003. We have
competent consultants and use their experience when it comes
to making the right choice of attachments. The machines are
ordered and built exactly to our wishes and expectations. Even
if a job is arranged at very short notice, we are able to bridge the
time for the delivery of a new machine with rental machines that
are available immediately.”
With 48 machines in operation nationwide, service is a key factor.
In most cases, a mechanic can be on site the same day or, at
the latest, the following day. “The availability and response time
of the Liebherr service teams are superb. The collaboration with
Liebherr is perfect for our needs,” Ralph Lang tells us.
Recycling Lahnau orientates its services to the individual needs
of the customer. Ralph Lang puts it like this: “We offer both
partial services and the complete execution of all quarrying and
preparation work. For the customer, that means that he doesn’t
have to invest heavily in new machines or take on new staff. Many
of our customers also appreciate the fact that they have full
flexibility in how they plan their delivery volume. This enables them
to respond to fluctuations in the market and, at the same time,
to plan reliably. You know how much a tonne of mined materials
costs at the start of the year, for example.”
All quarrying operations
under one umbrella
The company name Recycling GmbH Lahnau is misleading. For many years, the focus of the company’s activities
has been on quarrying operations, and its range of services covers all tasks relating to the quarrying and
preparation of natural stone, gravel, sand and clay. The professionals from the German state of Hesse do this with
75 large machines – 48 of them from Liebherr.

The four reverse gears on the articulated trucks are praised
especially highly. They make it easy to cover short distances in
reverse, alleviating the need for manoeuvring and saving lots of
time. The handling of the retarder is something else the drivers rate
highly. A lever on the dashboard freely adjusts the effectiveness
between 0 and 100 %, adjusting it perfectly to the profile of the
terrain. That relieves the service brake and creates greater safety.
