The SEHO LeanSelect is particularly designed to meet these challenges, featuring highest flexibility and outstanding return of invest. While the entire process is fully automated, loading and unloading of assemblies is done manually on two separate conveyors. This allows processing of up to five carriers at the same time. The work stations are arranged in a counter-clockwise U-shape, thus consistently following the Lean Equipment Design Guidelines.
