Abstract
Wheel chock systems for use at loading docks and other locations are described herein. In some embodiments, the wheel chock systems can include a wheel chock assembly that is positionable in contact with a vehicle wheel to restrain the vehicle at a loading dock. The wheel chock assembly can include a sensor target, and a corresponding sensor can be mounted to, for example, an outer wall of the loading dock or a wheel chock storage cradle mounted to the outer wall. In operation, the sensor can emit a wireless signal (e.g., an electromagnetic signal) that is reflected off of the sensor target and received back by the sensor when the wheel chock has been positioned in a blocking relationship relative to the vehicle wheel to restrain the vehicle at the loading dock. The sensor can be operably connected to a loading dock signal system (e.g., a signal light system) that displays appropriate signals to loading dock personnel based on detection of proper wheel chock placement. In other embodiments, wheel chock systems can include other types of devices for wirelessly communicating wheel chock placement information to loading dock systems. Such device types can include, for example, Bluetoo…
