Liebherr Colmar

Development of an autonomous workstation for rolling parts Liebherr France SA – Colmar site.

More than 60 years of experience in the production of crawler excavators

public works

More than 2,000 excavators leave the factory in Colmar, Alsace, each year. Since 1961, Liebherr-France SAS has been producing crawler excavators here for the most diverse fields of application, such as demolition, tunneling or embankment. Thanks to rapid growth and expansion of the product portfolio, a production company specific to mining excavators could be established in 2011. Liebherr-France SAS has since been manufacturing crawler excavators and special machines for mining and earthmoving, the steel industry and industrial handling, as well as for civil engineering and tunnel construction.

Customer problem

More than 2,000 excavators leave the factory in Colmar, Alsace, each year. Since 1961, Liebherr-France SAS has been producing crawler excavators here for the most diverse fields of application, such as demolition, tunneling or embankment.

Liebherr France consulted in 2021 for the replacement of its rolling installation which supplies all the components for its mechanical excavators with the objectives of quality, ergonomics and industrial performance.

The current station, beyond its rolling performance, did not allow a part to be loaded without having removed the part in progress.

The technical response from Picot experts

AMB Picot with SEREMA proposed an integrated solution including:

  • A radio-controlled gantry sweeping the entire area with a design suitable for picking up liebherr parts. They include mobile and orientable magnets
  • a table for feeding and centering the parts
  • A rolling machine with 4 rolls capacity 25mm over 2m
  • Easyroll patented software

The Picot team has developed specific Liebherr rolling algorithms for automatic program generation.

Customer point of view

Innovation & human values

Acceptance made on March 16 and 17, 2023 after 6 months of testing.

The customer represented by Mr Seitz (Director of the Colmar site) and Mr Grosshenny (Project Manager) congratulated all the teams for this work and the performance put in place.

Manager of the Colmar site

A strategic project for the Colmar site with remarkable work between the Liebherr and Picot teams.

Liebherr-France SAS manufactures nine different crawler excavator models in Colmar, as well as 23 different special equipment variants. For this, all machines are designed according to the requirements of the field and are continuously optimized – in terms of productivity, economic and energy efficiency.

2000 shovels come out of the Colmar factory every year.
