Lock & Turn – An Excellent Safety System
Kleemann's Lock & Turn, the innovative safety system for mobile impact crushers, demonstrates that safe operation, maintenance and fault elimination on crushing plants is by all means possible.
The system uses special keys that make work possible only on certain areas of the crusher. In these areas, personnel can open service flaps, or move or replace components. If you wish to work at another point, the keys have to be removed which results in automatic locking of the area previously worked on. The keys can now be inserted at a different point to enable another section of the crusher.
Apart from this key system, an attachable locking and rotation device is provided. This permits manual rotation and blocking of the crusher rotor in any position manually from the outside via a gear unit. The replacement of rotor ledges and the removal of blockages can now be carried out free of danger.
This has also been recognised by the Berufsgenossenschaft Rohstoffe und chemische Industrie (BG RCI) (Professional Association of Raw Materials and Chemical Industry) who honoured the developers of the Lock & Turn Safety System with its top award in 2014.
