Patent number: 9050947Abstract: A hydraulic leveling system for a vehicle has at least one set of hydraulic jacks that are extended by applying hydraulic pump pressure to an extend side of the jacks and are retracted by relieving hydraulic pressure from the extend side and applying hydraulic pressure to a retract side of the jacks. A pressure sensor has a pressure set point that when it is exceeded the system generates a signal indicating retraction of the jacks. The system operates so that after the pressure sensor set point is exceeded, the system turns off the pump and continues to hold open a valve that applies pressure from the pump to the retract side of the jacks for a period of time and that permits flow to continue from the extend side of the jacks to tank. After such period of time the system once again checks whether the pressure sensor is still activated and if it is not still activated, the system turns the pump back on and continues to retract the jacks.Type: GrantFiled: August 11, 2014Date of Patent: June 9, 2015Assignee: Actuant CorporationInventor: Harold W.
