If you have both a hydraulic dock leveler and an overhead door in the closed position and try to operate the dock leveler, the power of the dock leveler will damage the locked overhead door. If you have a vertical storing dock leveler in the rest (vertical) position and try and operate (lower) it when an overhead door is in the closed position, the dock will cause severe damage by impacting with the overhead door. In order to ensure that the dock leveler will not be able to operate when the overhead is in the closed position, you can equip the overhead door with an electronic interlock switch. Pit installed dock levelers or vertical storing dock levelers will only work if the overhead door is open.
