Since 1961 Liebherr has been manufacturing hydraulic excavators at its plant in Colmar, Alsace. Construction of mining excavators has also been part of the portfolio here for over 30 years. Liebherr-Mining Equipment Colmar SAS was founded at the same location in 2011 to cater for the particular requirements in open-cast mining. In addition to Liebherr-France SAS in Colmar, the production company operates a separate plant for the development, manufacture, and service of giant hydraulic excavators for open-cast mining as well as dredging excavators for maritime applications. Mining excavators from Colmar are used, for example, in the mining of gold, diamonds, platinum, coal, iron ore, and copper.
