Trapped Key Interlocks in Robust, 316 Stainless Steel
IDEM’s Skorpion Trapped Key System has been developed to provide extremely robust mechanical coded key safeguarding and interlocking for hazardous machinery and applications.
The trapped key system works on the principle of releasing heavy duty coded mechanical keys in a pre-determined sequence to ensure machine power has been isolated before any access can be made into areas where hazards or dangerous machinery is present.
Once the machine control has been isolated (achieved by turning the first key in the system) the removed key from the isolator is then used to release other trapped keys to enable access to the guarded areas.
Following release of the first key (isolator) safeguarding is achieved without the need for expensive and time consuming electrical wiring – thus making the system perfect for use in harsh and challenging environments and applications.
