Quality and sustainability

The highest quality is central to the goals of the Liebherr Group. Alongside this, protecting people and the environment is firmly rooted in our company guidelines. That is why ensuring high quality and sustainable products and processes is also a central aim for the gear technology and automation systems sector.

As a result of this, we have been certified according to standards ISO 9001(Quality), ISO 14001 (Environment) and ISO 45001 (Occupational Health and Safety Assessment Series) for years.

Quality management

“The highest quality in everything we do”

To fulfill this specification, quality management pays close attention to the strong collaboration between individual departments. The aim is to continually consider processes. Quality is no longer an individual point at the end of the production chain, but a supporting process across all phases of product development.

A team of specialists for product and process quality are responsible for this task. On the one hand, the aim is to reduce costs arising from poorer quality (e.g. warranty use cases) and reduce costs in the product development process on the other (process quality).

Quality assurance is made possible by a coordinated system of intermediate and final testing of the product. Quality processes are constantly monitored and optimized throughout the entire product development process with a meticulously coordinated “Quality Gate Systematics”.

Resource-smart manufacturing and production

“We want to fulfill our responsibility to society and the environment at all times.”

Consumption of energy sources like electricity, gas and district heating is monitored constantly using appropriate performance indicators. One specific example of efficiency in energy usage is our block-type thermal power station. It is driven by a Liebherr gas motor and uses its excess heat to cool (not heat) the production halls by means of an absorption chiller, even in summer. Around 10% of the power requirement at the Kempten site is definitely covered by the block-type thermal power station.

Materials with negative environmental effects like hazardous substances are only used following precise testing. If use of hazardous substances is inevitable, attention is paid to minimize pollutants as far as possible. For example, a series of measures taken in the paint shop has enabled to us to cut hydrocarbon emissions by more than half in recent years.

Sustainable product development

“We work systematically to always be a step ahead.”

Efficient energy usage and conserving natural resources in the production process is not only an internal aim, but also one which our clients increasingly require of us.

Therefore, we always try to reach our goals using the smallest possible number of materials. A program to generally overhaul used machines (REMAN) has been started, so we can continue to use materials even after the end of the (first) production cycle. The energy usage for operating our machines and systems is being continually optimized through the use of state of the art drive technology.
