Win-win all round
High-quality battery charging technology brings users and
battery dealers significant benefits in rental business
Wels, Austria – Fronius battery charging systems that use Active
Inverter Technology to charge traction batteries have economical
and ecological benefits for the rental business. Battery dealer
Keckeisen Akkumulatoren and its customer, the medium-sized lo-
gistics service provider Lebert, have opted for battery charging
systems from the Austrian manufacturer.


Based in Kempten, Allgäu, Franz Lebert & Co. sees itself as a proactive
and complete service provider for the logistics sector. In addition to its
head office in Kempten, the company has sites in Erbach and Baienfurt
(close to Ulm and Ravensburg respectively) and Kreuzlingen in Switzer-
land. Franz Lebert set up the company in 1954 in Kempten. Today, the
Lebert Group has around 400 employees, of whom 175 work in Kemp-
ten itself. In 2010, Lebert achieved a turnover of around 115 million
euro’s. As partners and franchisees, the four companies in the group
are part of the CargoLine network, a transport and logistics cooperative
for the standardised and system-supported transport of packaged
goods in Germany and Europe.

Customised service


André Biwer, the managing director of the Lebert Group, outlines the
group's range of services: "The requirements our customers place on a
logistics partner go well beyond standard haulage services. Analysing
our customers' requirements and developing customised solutions are
our main focus and the means by which we measure our success. Our
aim is to identify the specific requirements of a customer and to provide
specific, innovative solutions."


The contract logistics department is located in the head office in Kemp-
ten. A high-rise warehouse covering 39,000 m2 handles the picking and
ready-to-ship packaging of a variety of goods, particularly foodstuffs
and food-based products. The logistics department operates between
7am and 6pm on a single-shift basis. The storage and distribution of
finished products, the provision of production resources to production
on just-in-time or just-in-sequence principles are among Lebert's core
skills.


The haulage department, which covers around 7,500 m 2, works much
longer hours: three shifts a day, six days a week to be precise. This de-
partment deals with packaged goods, express products, partial and full
shipments and supply chain management. Up to 2,500 haulage orders
are processed every day, with an average dwell time of a product in the
transit warehouse of just 20 minutes. 180 HGVs leave the company
premises in Kempten every night to deliver goods to all points of the
compass. Numerous Jungheinrich and Still forklift trucks are used in the
haulage department so that goods can be turned round quickly and re-

liably. Also involved are electrically powered counterbalance trucks and
pedestrian pallet trucks with and without platforms for loads up to 2 ton-
nes. Different drivers operate the forklift trucks during each of the three
shifts. Due to the extreme working conditions, the trucks usually have to
be replaced after four years. The department currently employs 20
trucks around the clock. Replacement batteries are used to save time
and avoid interim charging.


A rental concept with full service has been in use for years in the case
of the forklift trucks. The benefit is fixed monthly rental instalments,
which helps the company keep a close eye on its costs. In the past,
both manufacturers supplied new trucks complete with the appropriate
traction battery and battery charger. However, Lebert was never really
happy with the servicing of its batteries and chargers. If any problems
occurred, it often took too long to rectify the error or Lebert was not
completely satisfied with the work done. As the forklift trucks were de-
livered to Lebert with batteries from different suppliers, there was often
confusion regarding responsibilities when servicing fell due. This led to
long downtimes for trucks and chargers, which had a profound effect on
processes and disrupted schedules.
Lebert came to call ever more frequently on the services of nearby bat-
tery dealer Keckeisen in Memmingen, who impressed with their quick
and reliable servicing. In 2010, Keckeisen impressed the logistics com-
pany by putting forward a sophisticated rental concept to reduce costs.
In addition to equipping the forklift trucks with traction batteries from the
outset, this also included replacement batteries and racks, battery
charging systems and a full service package. The Memmingen-based
specialist guarantees a four year service life for batteries and battery

charging systems. It is expected to take between two and three years
before the new concept is adopted across the company as a whole. For
commercial reasons, the system changeover will always take place
when a new forklift truck is purchased. Twenty of the 40 vehicles at the
Kempten site are now covered by the new concept.


For professional use


Using high-quality battery charging technology is an important part of
the Keckeisen concept. The company has therefore chosen Fronius
battery charging systems. "Lebert uses the Selectiva Plus range of
Fronius battery charging systems," commented Gregor Holzheu, sales
manager for industrial batteries at Keckeisen. He went on, "With the
Selectiva product range, the Austrian company provides Intralogistics
providers with battery charging systems that employ state-of-the-art
technology. The systems detect the age, state of charge and other im-
portant battery parameters fully automatically and charge them correctly
and precisely. In contrast to other technologies, the Fronius charging
technology means the battery only heats up a little during the charging
process. Gentle charging considerably increases the service life of bat-
teries. Only in this way are we able to guarantee a service life of four
years in three-shift operation at Lebert".


Eleven Selectiva Plus 2065 systems for 24V/250 Ah and 375 Ah batter-
ies, seven Selectiva Plus 2100 systems for 465 Ah batteries and two
Selectiva Plus 4120 systems for 48V/625 Ah and 750 Ah batteries are
used to charge the batteries of the 20 forklift trucks in the transit ware-
house at Lebert in Kempten. Selectiva Plus 4120 systems are used to

charge the batteries for the Jungheinrich EFG 220 and Still RX 20-18
counterbalance trucks. Replacement batteries are used in 15 forklift
trucks with 24 V batteries to give charging times of between 7.5 and 8
hours. The overall concept is designed in such a way that there is no
partial or interim charging during the shifts.


Intelligent charging systems


Fronius Active Inverter Technology achieves optimum charging power
levels due to the constant charging current and voltage. A normal 230V
connection can be used with the Selectiva Plus 2100 to charge vehicles
with 24V/465 Ah batteries and guarantee a charging time of between
7.5 and 8 hours. With this combination, most other charger brands
would require the installation of 400V three-phase AC equipment. Le-
bert was able to avoid expensive connection costs for the battery charg-
ing systems.


Lebert managing director, André Biwer, is very happy with the Fronius
battery charging systems: "Considerably less power is required to
charge the batteries compared with conventional 50 Hz transformer
technology. As less power is required, we are also reducing CO2 emis-
sions. This is becoming a much more important issue for the haulage
sector, since customers are increasingly looking at sustainability
throughout the logistics chain.
