  • Publication number: 20190031158
    Abstract: An example leveling/stabilization system for a vehicle includes a jack, an actuator, a user interface device, and a controller. The jack is adapted to be fixed to the vehicle and is extendable from a stowed position to an auto-deployed position. The actuator is coupled to the jack and is operative to extend and retract the jack responsive to signals from the controller. The user interface device is adapted to receive input from a user. The controller is responsive to an auto-deploy signal from the user interface and operative to provide the control signals to the actuator causing the actuator to continuously extend the jack from the stowed position for a predetermined time period, thereby positioning the jack in the auto-deployed position. No level sensor is required.

  • Publication number: 20160244030
    Abstract: An example extendable jack foot includes a foot pad, an extension member, and a handle. The extension member and the handle are fixed to the foot pad. The extension member also defines a slot. The slot is configured to accept a connecting pin, slidably coupling the extendable jack foot to the distal end of a jack leg. The extendable jack foot can be moved with respect to the jack leg by a user, adjusting the position of the connecting pin within the slot. Positioning the connecting pin in various seat positions within the slot extends or retracts the effective length of the jack leg. No detachable parts are required.
