Prevent drive-aways from manual doors
August 1st 2006

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

The interlock will only allow 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 comprises a solenoidcontrolled latch lock with auxiliary switch contacts.

The auxiliary contacts provide the option of controlling the use of a dock leveller or traffic lights.

In normal circumstances, a trailer is reversed into a loading bay. 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 bay door and, when turned, energises the Gallant's solenoid. The door can then be unlatched via the locking bolt and opened.

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.
