Fortress Interlocks describes tGard as a new approach to controlling access to hazardous machinery and equipment. It is a compact, metal-bodied safety system in which can be configured various safety products including electrical safety gate switches (with or without guard locking), mechanical trapped-key interlocks, and electrical operator controls, either as separate devices or integrated into one device.
As standard, tGard is offered as a customised product; tGard elements that can be incorporated include safety switches (solenoid and non-solenoid), personnel keys, emergency release, push buttons, emergency stop switches, indicator lamps, and a choice of operating handles for both hinged and sliding guard doors. These elements are simply selected and then assembled into a robust housing that is suitable for mounting onto machine guarding.
tGard is said to be quick and easy to install and can be mounted directly onto a flat surface, doors or extruded aluminium profiles without the need for mounting plates or brackets. It is sealed to IP65 as standard and has been designed to be fully compliant with current machinery safety standards.
