Keyless door interlock April 1st 2006 Castell has expanded its drive-away prevention system Salvo with the introduction of Gallant, a keyless door interlock for manually-operated 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 on the exterior wall of the bay.
While the key is trapped in the box, the trailer's brakes are locked on and the trailer immobilised.
Gallant comprises a solenoid-controlled latch lock with auxiliary switch contacts. These provide the option of controlling the use of a dock leveller or loading bay traffic light.
