Safety barrier systems for loading docks

摘要

Example safety barrier systems (10) for vehicle loading docks (12) comprise a retractable flexible barrier (40) with a special powered latching mechanism (50)that locks the barrier in place and prevents it from being retracted under certain hazardous dock conditions. In some examples, the barrier cannot be retracted when there is no vehicle at the dock while the dock's door (16) is open. In some examples, an alarm (54) is energized when concurrently the door is open, the barrier is retracted and there is no vehicle at the dock.
