Description

The following disclosure relates generally to systems and methods for controlling the operation of loading dock equipment and, more particularly, to control panels for operating loading dock equipment.

Conventional loading docks typically include an elevated opening covered by an overhead door in the side of a warehouse or other building. To unload or load a trailer or other transport vehicle, the doors on the back of the vehicle are opened and the vehicle is backed up to the loading dock door. A vehicle restraint (e.g., a mechanical hook, wheel chock, etc.) is employed to hold the vehicle in position in front of the loading dock door. The loading dock door is then raised, and a dock leveler is extended between the floor of the warehouse and the open end of the vehicle. Conventional dock levelers typically include a deck that rotates into position as a lip on the front edge of the deck extends outwardly and comes to rest on the bed of the vehicle. Once the dock leveler has been properly positioned, workers, forklifts, etc. can move back and forth over the dock leveler to unload and/or load goods and materials to and from the vehicle. Once the unloading and/or loading process is complete, the dock leveler can be raised and stowed and the loading dock door can be closed. The vehicle restraint is then disengaged from the vehicle so that the vehicle can pull away from the loading dock.

Loading dock equipment is typically controlled via a control panel positioned adjacent to the loading dock door inside the building.

  "description_excerpt": "The following disclosure relates generally to systems and methods for controlling the operation of loading dock equipment and, more particularly, to control panels for operating loading dock equipment.\n\nConventional loading docks typically include an elevated opening covered by an overhead door in the side of a warehouse or other building. To unload or load a trailer or other transport vehicle, the doors on the back of the vehicle are opened and the vehicle is backed up to the loading dock door. A vehicle restraint (e.g., a mechanical hook, wheel chock, etc.) is employed to hold the vehicle in position in front of the loading dock door. The loading dock door is then raised, and a dock leveler is extended between the floor of the warehouse and the open end of the vehicle. Conventional dock levelers typically include a deck that rotates into position as a lip on the front edge of the deck extends outwardly and comes to rest on the bed of the vehicle. Once the dock leveler has been properly positioned, workers, forklifts, etc. can move back and forth over the dock leveler to unload and/or load goods and materials to and from the vehicle. Once the unloading and/or loading process is complete, the dock leveler can be raised and stowed and the loading dock door can be closed. The vehicle restraint is then disengaged from the vehicle so that the vehicle can pull away from the loading dock.\n\nLoading dock equipment is typically controlled via a control panel positioned adjacent to the loading dock door inside the building.",
