Trapped key interlocks

October 11, 2010
Castell equipment has been added to Tapeswitch Corporation’s product line and the trapped key interlocks and loading dock guarding systems are now available in the U.S.

The trapped key interlocks ensure that a predetermined sequence of tasks is followed to control process risks and equipment hazards. Valves, actuators, switches, doors and processes are physically locked in a state until the right key is used. The next step is only started once the previous step has been completed.

The Salvo system prevents trucks from driving away during loading or unloading. The gladhand lock attaches to a brake line, releasing a uniquely coded key. In an automatic system, the key is then used in an exterior control panel, which disengages the automatic door interlock so that workers can safely load or unload.
