Salvo Range




Salvo prevents the accidental drive-away of a vehicle during loading or unloading of goods at a loading bay. The Salvo links the articulated trailer to the loading bay door during the loading or unloading of goods.

The loading dock is one of the most dangerous areas of a warehouse, and 25% of all industrial accidents occur here, and for each accident that occurs there are around 600 near misses. Unscheduled vehicle drive away is one of the high risk factors in loading bay safety and accidents of this nature can result in severe injury or even death for warehouse operatives.


The Castell Salvo system can ensure that this risk is controlled and eliminated by integrating vehicle immobilisation with warehouse/vehicle access, and by applying trapped key interlocking technology into this process.

How Does Salvo Loading Bay Safety Work?

The Salvo Susie is fitted to the emergency air line coupling when the trailer has been reversed into position at the bay. After successful fitment, a Salvo coded key is released from the Salvo Susie, locking the unit firmly onto the coupling. The coded Salvo key can only be released once the Salvo Susie has been fitted to the brake coupling. The coded Salvo key is then taken to the corresponding loading bay door and used to open the door.


The secret of the Salvo system is that only one Salvo key exists per bay, thus ensuring that the door can only be opened ONCE the trailer has been secured in place. To ensure the integrity of the system, each bay will have a different code.
