Switchgear Application with Trapped Key Interlock Safety System
Protecting Personnel during Switchgear Maintenance
Within a substation, KIRK® trapped key interlocks are used to ensure the isolation of hazardous energy for several switchgear maintenance applications. Preventing the paralleling of two energy sources, ensuring a breaker is locked open (or closed) for maintenance operations, preventing the disconnection of breakers under load, and minimizing the potential of a hazardous arc flash are just a few applications where trapped key interlocks can be found.
Salvo loading dock safety systems prevent drive-aways during loading/unloading by interlocking the trailer’s air brakes with the dock door. This ensures that the trailer cannot depart until loading/unloading is completed and the dock door is locked closed. Salvo keeps your personnel and equipment safe by – eliminating human error.
The Coupler Interlock System is an electromechanical interlock that is suitable for controlling access to tubular bulk material transfer systems, such as those used for silo storage, mitigating the risk of lost material and cross contamination during the loading or unloading process.
