We offer a selection of technical articles dealing with the safety of machines and plants - both in general and on particular aspects of product families for machine safety. Some of the contributions are from Schmersal employees, others are written by independent specialists, e.g. from industrial assessment organisations. The applicable PDF file can be stored on your computer by means of the download function.

   


Press technology: Safety and productivity are not a contradiction

(27.08.2008) 

When observing the entire mechanical and plant engineering field, two hand switches surely belong to the more rare, but more costeffective safety devices. However, they are not widely used in metal-working, especially in press technology. The Pressen- und Maschinenbau Erfurt GmbH – short: PME – relies on two-hand control panels by Elan for their metal forming presses. more



EN ISO 13849-1: New category principle for machine safety

(19.08.2008) 

The "category principle" for Safety-Related Parts of Control Systems (SRP/CS) of machinery belongs in the past: The familiar control unit categories of EN 954-1:1996 have been replaced by performance levels of EN ISO 13849-1:2005 and must be applied by the end of 2009. What now changes for the designers and safety engineers? more

Special operating modes for set-up mode and process observation

How can the job of the machine setter or operator be facilitated, whilst it is still guaranteed that he works safely during the set-up or after a size change on the one hand and that he has the best visibility on the process so that he can intervene in case of an emergency on the other hand? The new Machinery Directive provides – under strictly defined conditions – the possibility to use special operating modes; an opportunity, which the machinery builder should take advantage of. more

Control devices for fish and meat processing: ergonomic and hygiene-compliant

Fish or meat? The engineers from the machinery building company Rud. Baader GmbH & Co.KG, located at Lübeck in North-Germany, know all the ins and outs of both basic foodstuffs. Baader is international market leader in the field of fish processing machinery and also a leading supplier of meat processing machines. The company has a high degree of vertical integration in order to guarantee a high quality level and also assembles components such as the control devices in the own plant. Here, the hygiene-compliant control devices and indicator lights from the N-programme from Elan are used. more
