Job Report
The Liebherr L 524 and L 542 wheel loaders
in use for collecting recyclable material
at Böhme GmbH in Rehau

Situation
Task
Böhme was founded as a haulage company in 1938 by Willy
Böhme in Rehau. In 1951 the company added trench and sewer
cleaning divisions. In 1954 the company extended its activities
to include waste disposal. Böhme GmbH Wertstofferfassung
was founded in 1985 by Rudolf Böhme and is primarily focused
on the collection and sorting of recyclable materials such as
green, brown, clear and mixed glass, aluminum and tin cans,
paper and plastic packaging waste and waste paper. The
company has a storage capacity of approx. 1,500 tonnes for
deliveries of paper. The company also has a storage capacity of
approx. 200 tonnes for plastics. At full capacity the workforce
works a 4-shift model on every day of the week. Today the
company is managed by Stefan Böhme, Rudolf Böhme’s son.
Once all the recyclables have been collected on the large storage sites, they are transported to a material preparation system
for sorting. They are transported on conveyor belts. To ensure
that the materials are evenly distributed on the belts they are
first fed into metering bunkers. After the initial automatic sorting process in the system, the recyclables are sorted manually.
The next step is to press the fractions into homogeneous bales
for transporting in a bale press, after which they are pushed
into the bale storage facility where they are stored separately
by material type. After this they can be delivered to recycling
contractors.
The company has been using three Liebherr L 524 wheel loaders
for several years. These operate for around 2,500 hours per
year and are used to form the waste into heaps and then feed
it on to the conveyor belts. The Liebherr wheel loaders have
proved to be an invaluable tool both for forming the heaps near
the sorting system and in the actual material handling process.
Since the wheel loaders can be used for a wide range of jobs
in the company and the management team are delighted with
them, the company placed an order for another wheel loader in
spring 2013, but this time an L 542.

Solution
The L 542 also features the hydrostatic travel drive which has
proved so successful in Liebherr wheel loaders. It enables
the Liebherr diesel engine to be installed in the best possible
position. By comparison to rival machines, this unit also arrives
with a lower net weight and a high tipping load since the diesel
engine is used as a natural counterweight. Compared to
machines form other manufacturers, this represents a reduction
in fuel consumption of more than 30%.
Stefan Böhme, manager of the recycling company, also
highlights another positive effect. ”The hydrostatic travel drive
also makes for minimum braking and tire wear due to its infinite
traction force control. Despite the very demanding work, the
tires have suffered very little wear at all.”

The wheel loaders are fitted with a P-kinematic ”High Lift” arm
which, when combined with the high-tip bucket, enables the
material load to be loaded into the ”walking floor” trailer at a
height of over four meters. The high-tip function also allows
the loaded materials to be compacted on the ”walking floor”.
The L 524 and L 542 models achieve a greater emptying height
compared to rival wheel loaders with a similar tipping load. The
rapid change system allows the operator to select a bucket
suitable for the material.
Liebherr wheel loaders also score heavily in terms of service
and maintenance. The installation position of the cooling
system is particularly advantageous for jobs in dusty and dirty
environments. The cooling system is immediately behind the
driver’s cab and ensures that it only draws in air with a low dust
content. This ensures that the cooling system becomes less
contaminated, thus reduce the maintenance and cleaning work.
The dust filter also prevents drawing in fluff and dust particles
in advance. Since the fan also has to be cleaned after a certain
length of time, the machine was also fitted with a reversible fan
drive unit.

The Liebherr Standard Consumption Test –
easy to reproduce and practical.
The Liebherr Standard Consumption Test determines the number of
loading cycles that can be carried out with 5 litres of diesel.
The material is taken from pile A and carried over a distance of 20
metres to point B. The time needed for each working cycle should
be 35 seconds. Discharge at point B should take place from a height
of 2.5 m. The working cycles continue until the 5 litres of diesel in
the external measuring tank have been used up. The loader’s fuel
consumption per operating hour is calculated as follows:
