An improved jack pad for supporting a jack foot having a foot plate includes a body having an upper surface and a lower surface joined by a side wall, and defining a recess configured for receiving the foot plate and having a retaining lip for securing the foot plate therein. The jack pad may provide for the drainage of water from the pad.

A system for supporting a vehicle. The system may include a vehicle jack in mechanical communication with a jack foot and a striker plate. The jack foot is rotatable relative to the vehicle jack on a rotation axis disposed on the vehicle jack and perpendicular to a long axis of the vehicle jack. The jack foot includes a base at a distal end of the jack foot. The jack foot also includes a cam surface at least in part at a proximal end of the jack foot. The cam surface is aligned with the striker plate and interacts with the striker plate to rotate the jack foot in response to movement of the vehicle jack from a lowered position to a raised position.

A mobile pole for temporary support of one or more electrical lines includes a boom assembly mounted on a wheeled trailer. The boom assembly includes a plurality of segments pivotably attached to one another. Actuators acting between the segments effect pivoting motion to deploy and stow the segments. A utility pole having one or more cross members is mounted on a free end of one of the segments. The utility pole is rotatable about its longitudinal axis to orient the cross members relative to the electrical lines.

A tire replacement apparatus is disclosed that has an electric motor with a drive shaft and a first gear concentrically connected to the drive shaft. The first gear may connect to a symmetrical bolt locking gear array having several bolt locking gears arranged such that each bolt locking gear rotates in the same direction that the first gear rotates. Each bolt locking gear may have a cylindrical hole at its center. The cylindrical hole may be outlined with an inner spiral thread, which connects to a set of power bolts that are outlined in an outer spiral thread which interlocks with the inner spiral thread.

A vehicle leveling system includes a jack adapted to be mounted to a vehicle frame without modifying the vehicle frame. In a particular embodiment, the jack includes a first bracket adapted to urge against the bottom and side surfaces of a member of the frame and configured to be fastened to a member of the frame through a manufacturer-provided aperture in the frame. The jack additionally includes a second bracket to couple the first bracket to the jack. In a more particular embodiment, the first bracket includes a horizontal adjustment feature, and the second bracket includes a vertical adjustment feature.

A recreational vehicle includes a frame, left and right air suspensions, a front jack, a tilt sensor configured to measure lateral and longitudinal tilt data associated with the frame, and a controller. The controller is configured to receive the lateral and longitudinal tilt data to thereby level the frame laterally via operation of the left and right air suspensions and level the frame longitudinally via operation of the left and right air suspensions and the front jack. Methods for performing a leveling operation include utilizing left and right air suspensions of the recreational vehicle in combination with operating a front jack of the recreational vehicle until the recreational vehicle is level along lateral and longitudinal axes.
