2 L 550
Situation
In 1994 René Burkhardt at the tender age of 21 took the bold
step to start his own business and founded Baggerbetrieb
Burkhardt based in Thonhausen, Thuringia. He provided his
customers with excavator services using a Liebherr A 900.
As the business grew the company expanded quickly and
moved into new business sectors. In 2001 the subsidiaries
Baggerbetrieb Burkhardt GmbH and Transport-Recycling-
und Landschaftsgestaltung GmbH were founded in order to
separate excavator and transport services. Then in 2004 the
company expanded again with the purchase of MTB GmbH.
Today the company’s services include complex bridge
demolition work, this includes work for German railway and
autobahn bridges, the removal and demolition of buildings
and structures, earthworks, road and sewer construction,
rail track work with road/rail excavators, bulky goods and
heavy transport and finally gravel extraction and the recycling
of buildings materials. Earth and timber in its own mine.
There are around 70 people in the workforce, some of which
have been working for the company since it was founded and
are among the top personnel in their industry, an aspect of
which Mr Burkhardt is extremely proud.
Task
The company planned to purchase a new wheel loader
which must meet very specific requirements for use in
the mine. The machine must be capable of breaking the
very hard and abrasive gravel which contains a very high
proportion of pebbles out of the wall and load it on to trucks.
The wheel loader must also be able to travel from the deeper
section of the gravel quarry quickly on some lengthy tracks to
all areas of the mine. Other tasks include feeding the crusher
and screening systems, the removal of the material ejected
from the conveyor belts and transporting it to the landfill site.
This results in a handling capacity of over 1500 tons every day.
The machine should therefore be reliable, safe and comfortable,
require little service with good service availability and above
all economical in terms of fuel consumption.
