Family business since 1861 with about 320 employees

Second biggest wood processing company in Switzerland

Saw mills in Switzerland and France

The company also operates a high-performance processing industry with drying systems, planing mills, wood glue systems, stone works and a pressure treatment plant

Over 2,200 cubic meters of fresh wood is processed daily

Replacement of trailing cable equipment with IWLAN should increase the operational reliability of a gantry crane

Despite its outdoor installation, this crane must be ready to operate safely in all weather conditions at all times of the year

High requirements on the availability of the crane

Control by means of a SIMATIC S7-300 with CP 343-1 for connection to Profinet

Wireless network supplied via an Access Point Scalance W784-1

In the cabin, the data is converted back to Profibus by means of the client IWLAN/PB link

To prevent unauthorized interference by third parties, the wireless network is protected by encryption and passwords

Simulation with SINEMA E beforehand in order to check feasibility under the specific conditions of use and rule out foreign signals

High availability of the gantry crane

Safe communication via IWLAN

Thanks to this WLAN solution, both the need for labor- and cost-intensive maintenance work on the control cable and interference from the power cables to the crane trolley are completely eliminated

The wireless solution was implemented with standard components which are available at all times and is thus expandable, even if lightning should ever strike

Fast commissioning in only two working days
