Machine & Operator Safety
Extracted key adaptor
September 13, 2011 by Manufacturing AUTOMATION
Safety interlocking company Fortress Interlocks has added a new extracted key adaptor, the E1, to its amGard range of modular safety gate switch interlocks. The E1 ensures that the door to hazardous machinery cannot be opened without removing the safety key, and the machinery cannot then be restarted until the key is returned. The mechanism is designed to trap an actuator in the head unit until the key is removed, which then allows the gate to swing over the keyhole. While the actuator remains out of the head, the gate remains over the keyhole, preventing the key from being returned to the lock. E1 ensures a specific sequence of operation and can be stacked or combined with other adaptors; up to five key adaptors can be used in one configuration. E1 also provides a link to Fortress’ mechanical mGard range of interlocks. E1 works with access key and safety key adapters, Fortress amGard LOK or STOP bodies, and is suitable for either hinged or sliding door applications. The modular arrangement of amGard allows customers to tailor and configure products to suit their application. AmGard is a heavy-duty interlocking range that provides both safety and security by controlling access to dangerous machinery and safeguarding personnel. A variety of actuators and adaptable mounting arrangements helps sustain a long life cycle and minimizes downtime, the company says.
