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), ISO 45001 (Occupational Health and Safety Assessment Series) and ISO 50001 (Energy Management) 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-saving manufacturing and production

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

The consumption of utilized energy such as electricity, gas and district heating is continually calculated using ultra-modern measuring technology and monitored by the use of corresponding key figures.

We are constantly investing in the latest technology in order to lower the values. At the same time, we are continuing to expand the shift from fossil-based energy to sustainable solutions. There is a specific example of this in the central paint shop area where a dryer previously heated with gas has been converted to district heating and lowered in temperature at the same time. Investment in battery-powered electric company vehicles for business trips is a further step towards sustainability.

Materials with negative environmental effects and hazardous substances are avoided as far as possible. If use of hazardous substances is unavoidable, we make sure that, as far as possible, environmental effects are minimized. For example, a series of measures has enabled us to reduce the use of climate-damaging hydrocarbons (VOC) in production by more than 70% 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.
