A few words
When we started, in 1987, to translate our ideas into products like Double Lock, we did not have a clue as to where our entrepreneurial trip would end. At the time, production, design, and sales of Double Lock 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 Double Lock have been designed and successfully launched in the machine safety devices market
. With our subsidiaries and distribution partners for Double Lock 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 Double Lock, and for this reason we are proud to connect our own name with our Double Lock and services.

SAFETY INTERLOCKS and double lockAdvantages of Haake double lock
Benefits offered by the trapped-key system, e.g. double lock:
- 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 interlocks 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. double lock) with multifold applications for:
Oil / gas
Power generation / distribution
Switch HST-S and Double LockDouble Lock: 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.
Double Lock: 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.
