When working in energy environments such as wind farms and power plants, employee safety is a top priority. The risk to life is incredibly high because of the electrical currents inside such facilities. With our interlocking product range, you can create complex locking systems that manage access to different areas. You can also have two person authentication protocols and trap key systems to secure high danger zones.

Using a bolt lock, for example, means that you don't need to run power wires to the gate you wish to secure. Instead, the power is disconnected via a trapped key rotary switch on a control panel, and the key is then hand-carried to the gate by the user.

Cam locks are used for the mechanical locking of circuit-breaker switches, inverters, disconnecting switches and earthing switches of most medium voltage cells, transformers, etc. Generally, a cam is fixed on the rotor and is directly led by the key. They mainly act as blocking elements in a device or mask the entrance of a crank for the operation of the disconnecting switch for example.

The door locks are used on both access points (hatches, doors, gates ...) but also on removable heads of transducers. When access is opened and the striker is not introduced into the casing of the lock, you can not remove the key. Depending on the lock, it is possible to have one, two or three cylinders.

An Exchange Box works by a series of released and trapped / captured keys. The only way to release a trapped key is to ensure that all currently released keys are present and locked into the exchange box. Once the trapped key has been released, this will then trap all other keys in the box.

This improves security in situations where access doors/gates need to remain locked. The key can only be removed from the lock in the locked position, at which point it is re-introduced into the exchange box.
