LIGHTING AND SIGNALING SYSTEMS FOR LOADING DOCKS |
摘要 |
A safety system for a truck loading dock with an elevated platform provides an alarm that warns of a hazard at the loading dock such as a forklift operating inside the truck or a falling hazard that may exist due to the dock door being open while a truck is not present at the dock. In cases where a dock's open doorway is protected by a barrier that can be opened or closed, the alarm can be de-activated by closing the barrier. In some examples, the safety system includes a remote body sensor that detects when someone or something is near the doorway. In response to the body sensor, a second, more pronounced alarm can warn of more imminent danger where someone on the platform may be too close to an open doorway when a truck is not present.
