Kardex Mlog to refurbish at Würth in Switzerland

14 October 2024, Company News

Würth International AG, based in Chur, Switzerland, has commissioned Kardex Mlog to refurbish the high-bay warehouse at its logistics center in Landquart. The project will focus on the two stacker cranes supplied by Kardex Mlog, which have been operating reliably since 2008. Some of the machine components have been discontinued by the manufacturer and can no longer be sourced. To ensure plant availability in the future, the goal is to sustainably upgrade to state-of-the-art machines. The project will be carried out and completed within a very short timeframe during ongoing operations between October and December 2025.

The two stacker cranes of type ecoMAN RE-1200 are approximately 22 meters tall and can each carry loads of 1,000 kg. The load handling device is a telescopic fork for single-deep storage and retrieval. The refurbishment of the machines includes re-profiling the rails, renewing the control and drive technology, and replacing the conductor line.

The installed Siemens controls of type S7-315-2PN/DP were discontinued as of 2020. These will be replaced by on-board, programmable logic controllers (PLC) of type S7-1515 F. In addition, decentral input and output modules of type ET200SP from Siemens will be installed. These Profinet-compatible assemblies record the lift carriage sensors and forward all signals onto the higher-level PLC.

To optimize the drive behavior of the stacker cranes, the drive controls are also being updated. The same applies to the gear motors, which have also been discontinued. With the replacement of the drive technology in both the chassis and lift units alongside the telescopic forks, the machines will be state-of-the-art.
