Abstract
A dock leveler includes a support leg system configured to remain in a support position when the dock leveler descends rapidly and retract when the dock leveler descends slowly. A disengaging system is also included to disengage the support legs from retracting when the dock level lip is in a pendant position. A method of operating a dock leveler includes keeping a support leg in a support position when a dock leveler descends rapidly and retracting a support leg when the dock leveler descends slowly.
