Castell launch new spring-loaded interlock

New KSP interlock from Castell

Safety specialist says latest KSP unit provides more efficiency than traditional bolt interlocks

INDUSTRIAL safety specialists Castell have launched a new spring-loaded lock, the KSP, to increase efficiency in traditional bolt interlock applications. The KSP is a spring-loaded version of the Castell K lock and uses an internal spring to automatically extend the lock’s bolt to its fullest extent when circumstances permit.

The key-operated mechanical interlock is suitable for the safe locking of simple actuating mechanisms. It is generally used at the start of a process and traps a key while equipment is running.

 

When the equipment is switched to a safe state and the aperture in the actuating mechanism is aligned, the spring-loaded bolt automatically extends and is locked in position. This gives an advantage over existing bolt locks as the operation happens immediately and there is no need for human intervention.

Once the equipment is in a safe state the key is released and can be used to gain access or start a separate process. The key must be inserted and turned, retracting the bolt, to allow the actuating lever to be moved again.

Castell technical director Paul Marks said: ‘We were already using a spring-loaded lock within our product range and realized that the same device could deliver significant benefits elsewhere for our customers. We view the KSP as an important addition to our existing K bolt interlock range.’
