A few words to door locking

When we started, in 1987, to translate our ideas into products like door locking, we did not have a clue as to where our entrepreneurial trip would end. At the time, production, design, and sales of door locking took place in our parents’ garage! Our’s would have been a short story, if not for the support of our very first customers and suppliers. Because of their original commitment to us, absolute customer orientation is the number one priority for our colleagues and us.

Since our founding, several product groups like door locking have been designed and successfully launched in the machine safety devices market.

With our subsidiaries and distribution partners for door locking in the major industrial countries, we are able to serve our customers in all aspects of labor safety. As a family-owned company, we attach the highest importance to quality, and for this reason we are proud to connect our own name with our products like door locking and services. We look forward to your enquiries. We also welcome your comments and any criticism, as this will help us to improve and to create new solutions for door locking.

SAFETY INTERLOCKS and door locking

High safety.

door locking: Such guard locking devices are for instance key-operated mechanical interlocks, also called trapped-key systems. They are based on the easy-to-understand premise that a key cannot in two places at the same time - it can for instance be inserted in a switch OR be used for opening a guard.
door locking: Another safety-relevant feature is that a key can only become free in a safe condition, when there are no hazards - a switch is turned off, a guard interlock is closed and locked. The big advantage of the system is the fact that a certain sequence of steps can be predetermined when designing the system. It is not possible to deviate from this sequence - thus a high degree of integrity is achieved. So virtually any hazard can be eliminated.
