Keyless drive-away prevention
February 1st 2006

Castell has expanded its Salvo drive-away prevention system with the introduction of Gallant, a keyless door interlock designed for manually-operated loading bay doors.

The interlock only allows the door to be unlocked and opened once the Salvo permit key has been inserted into a separate control box located on the exterior wall of the loading bay; while the key is trapped in the box, the trailer's brakes are locked on and the trailer immobilised.

Gallant is a solenoidcontrolled latch lock with auxiliary switch contacts, which provide the option of controlling a dock leveller or loading bay traffic lights.

In normal circumstances, a trailer is reversed into a loading bay and a trained operative fits the Salvo Susie lock to the emergency airline coupling, releasing the permit key. The key is inserted into the control box adjacent to the door and, when turned, energises the Gallant's solenoid. The door can then be unlatched via the locking bolt and opened.

As long as the door is open, the bolt cannot be reinserted into the Gallant and the interlocking sequence reversed. Only when loading/unloading is complete, and the loader driver has retreated from within the trailer, can the bay door be closed and the interlocking sequence reversed, allowing the vehicle to depart.
