Pedestrian-Vehicle safety systems for loading docks are disclosed herein. An example safety system includes a first sensor to monitor a first area adjacent a dock, a bi-directional sensor to signal both incoming movement and outgoing movement of a vehicle relative to the dock, and an incoming sensor to signal only incoming movement of the vehicle relative to the dock. A signaling device is responsive to outputs of at least one of the first sensor, the bi-directional sensor, and the incoming sensor.

Pedestrian-vehicle safety systems for loading docks

Pedestrian-Vehicle safety systems for loading docks are disclosed herein. An example method disclosed herein includes sensing whether a person is within a certain area adjacent a dock face of a loading dock, emitting a first signal in response to sensing the person being present within the certain area, sensing rearward movement of a vehicle toward the dock face, emitting a second signal in response to sensing rearward movement of the vehicle while the person is not present in the certain area, and emitting a third signal in response to sensing both the rearward movement of the vehicle and the person being present within the certain area.

A horizontally sliding door includes a resilient retention system that helps hold a door panel tightly against its seals when the door is closed, and resiliently releases the door panel when an external force displaces the panel beyond its normal path of travel. If the door panel is displaced off its normal path, the resilience of the retention system or simply opening and closing the door automatically returns the panel back to normal operation. The resilient retention system can be installed off the floor, so the system avoids creating a tripping hazard and avoids being damaged by nearby vehicles.
