Abstract
A central pressurized air supply selectively couples pressurized air to one or more dock levelers to pivot a hinged ramp of a dock leveler. Each dock leveler includes an inflatable member to which the pressurized air is selectively coupled, and the inflatable member is arranged to pivot about the hinged ramp of a respective dock leveler. A control system allows continued operation of the system during adverse conditions.
