Safe SILCL3 PLe positioning of the driving unit

With the certified Safe Linear Positioning safety system positions and speeds of highly dynamic stacker cranes are detected and analyzed in constant cycles by the safety control (according to DIN EN 528:2009-02 - Safety requirements for rail dependent storage and retrieval equipment) and by using a bar code tape. Therefore sections can be defined where the driving unit is only allowed to move with reliably reduced speed to prevent accidents.
