Omron's DSS Trapped Key Loading Dock Safety System protects dock workers

Omron Automation and Safety's DSS Trapped Key Loading Dock Safety System is designed to protect dock workers by enforcing a safe sequence of actions. DSS uses the trapped key concept – in essence this means that the loading dock door cannot be opened until the trailer brakes are locked. Once the trailer brake glad-hand is set, the glad-hand key is released ,allowing the loading dock door to be opened. This solution is designed to work with all vehicle types and can interlock with other existing dock safety products.

Operators lock the trailer brakes, open the loading dock door (automatic outdoor or manual indoor options are available) and safely load/unload and depart. When air is released from the trailer’s brake line, the mechanical brakes automatically engage.  The system keeps the brakes locked until loading/unloading is complete.
