Our safety mats are built up of mechanically opening break contacts connected in series, in the form of a contact mat (see also our catalogue HSC Safety Edges). Current conducting contacts plates and insulating wedge elements are alternately lined up on an ex-pander cord. By pre-tension, the contact plates are pressed together, and the current circuit is made. When stepping on the safety mat, at least one of the contact plate pairs is separated by action of the wedge elements, and the current circuit is broken (see fig. bottom right).
bolting device and Safety Interlocks
Welcome to Haake Technologies in Germany.
Manufacturer of bolting device, locks, safety mats, safety edges and bumpers
A few words
When we started, in 1987, to translate our ideas into products like bolting device, we did not have a clue as to where our entrepreneurial trip would end. At the time, production, design, and sales of bolting device took place in our parentsí garage! Ourís 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 bolting device have been designed and successfully launched in the machine safety devices market. With our subsidiaries and distribution partners for bolting device 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 for bolting device, and for this reason we are proud to connect our own name with our products and services. We look forward to your enquiries. We also welcome your comments and any criticism to our bolting device, as this will help us to improve and to create new solutions.

SAFETY INTERLOCKS and bolting device
Such guard locking devices (bolting device) 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.
Another safety-relevant feature (bolting device) 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.
Advantages of Haake bolting device
Benefits offered by the trapped-key system, e.g. bolting device:
- high safety, individual codes
- only pre-determined sequences securing safety are possible
- no spare tongue "in the pocket"
- no cables to the individual guards (cost saving, faults prevented)
- easy retro-fitting
- guard bolting device have locking feature
- particularly suited when there are different energy sources for the machine (electric, pneumatic, ...)
- in areas where people might get trapped: personal safety key
- simple possibilities for teach in
- time delay due to key transfer between switch and guard interlock - run-down processes come to a standstill (if necessary, extend by additional unit)
Haake offers safety interlocks (e.g. bolting device) with multifold applications for:
Oil / gas
Power generation / distribution
Switch HST-S and bolting device
bolting device: The switch HST-S is used for isolating the machine, in order to permit safe access. After the voltage has been switched off, the previously trapped key can be removed and used for the next step in the sequence, e.g. opening a guard. The unit is available as an enclosed (IP 65) or a panel mount version. Versions with multiple locks (enclosed version sheet-steel up to 4, panelmount version up to 10) are also available. Further, versions in explosion-proof enclosures (ATEX zones 21 & 22 and 1 & 2) can also be supplied.
