Abstract
A wheel chock system includes a chock, a sensor disposed within the chock to sense the proximity to the tire, an outside light box, and an inside control panel. Lamps on the outside light box provide a visual indication as to when the chock is in close proximity to the wheel. Lights on the inside control panel provide a visual indication of the loading dock safety status. The wheel chock system further includes a controller coupled to the inside control panel, programmed to change visual indications of both the outside light signal box and the inside control panel, based at least on the sensor and a loading dock door sensor. The wheel chock system further includes a camera positioned to view the tire and the chock and convey an image of the tire and the chock to a display on or near the inside control panel.
