To mitigate the multidimensional dangers facing workers at loading docks, Rite-Hite (Milwaukee, WI) has introduced two new products to its Rite-Vu Light Communication Systems family — Pedestrian-Vu for the dock’s interior and Approach-Vu for its exterior. Inside the dock area, Pedestrian-Vu uses motion-sensing technology to trigger a bright blue light that projects onto the dock leveler when it detects material handling equipment or a pedestrian’s presence inside the trailer. Pedestrian-Vu also works in conjunction with Dok-Lok products to alert any dock worker or forklift that enters an unsecured trailer. The blue light flickers as an audible alarm alerts the unsuspecting dock worker that they’ve entered an unsecured trailer, while the external light system simultaneously changes to red, warning the truck driver that there is activity inside the trailer. Outside the dock opening, from a fixed location above the dock door, the new Approach-Vu sensor detects the motion of a tractor-trailer backing into a dock position. A visual and audible alarm located on the Dok-Lok vehicle restraint alerts dock workers and pedestrians in the drive approach of the impending danger. This multisensory alert system is particularly important because ambient noise often masks the sound of a cab’s noisy engine, which can be 70 feet or more from the back of the trailer.
