In 2008, Swedish Work Environment Authority tightened control of machine safety in sawmills. This after many injuries in the industry. Knäredssågen got that other sawmills tremendous of work.

 

After some planing we decided a large master safety PLC for the entire facility. We started with the most difficult.

Trying to secure the entire timber intake including wheel loader driver. After several positive signals from the Swedish Work Environment Authority, we continued with the rest.

 

Many parts of the production were impossible to secure. In these cases, there were new machine instead.

 

After much consultation particular with Beijer Electronics (Johan Torstensson), Sick AB, Axelent (Daniel Axelsson) and all the employers we went beyond expectations.

 

After a few years was the most engaged, according to the same principle.

 

In the current situation, we have 73st variety protection system such as light gards, doors, ropes and emergency stops connected. These protection breaks up a total of 34st safety zones.

 

The safety PLC that keeps track of everything is a Mitsubishi QS. To make it easier for operators show all status through a Citect Scada systems.
