A lifting jack system includes a lifting bar; having a track of teeth running vertical along one edge of the lifting bar; and a foot secured to a base of the lifting bar; a lifting head secured around the lifting bar and vertically moveable along the track of teeth; a nose, extending outward from the lifting head for securing to an item to be raised; a gear system housed within the lifting head, the gear system having a safety gear with asymmetrical teeth; a spring loaded pawl engaged with the teeth of the safety gear; and a round gear with symmetrical teeth engaged with the teeth of the safety gear and the track of teeth of the lifting bar; and a ratchet bar secured by a ratchet to the safety gear and extending outwardly from the lifting head; the ratchet bar is to turn the safety gear via the ratchet, thereby engaging the safety gear with the round gear, the round gear then engaging with the track of teeth to raise the lifting head along the track of teeth; and the spring loaded pawl engages with the safety gear to prevent downward movement of the lifting head.

A storage device for a vehicle is disclosed. In one embodiment, the storage device has an exterior housing, an interior container, and a scissor lift mechanism. The scissor lift mechanism is located within the exterior housing and is operatively connected to the interior container. The scissor lift mechanism has a raised position and a lowered position. The interior container is within the exterior housing when the scissor lift mechanism is in the lowered position. The interior container is at least partially located outside the exterior housing when the scissor lift mechanism is in the raised position. The scissor lift mechanism includes crossed bars that pivot about a bolt or pin in scissor-like fashion to raise or lower the interior container. An actuator pivots the cross bars to the raised position and is oriented and connected to the crossed bars to have an upward vertical force component throughout the raising operation.

A lifter is provided with operating levers, which, against driving forces of actuators that switch the ratchet pawls to unengaged orientations, switch the ratchet pawls to engaged orientations of being engaged with ratchet gears, is provided with a link mechanism, which, when a workpiece support base is being lowered by collapsing motions of a pair of right and left crosslink mechanisms supporting the workpiece support base and a difference arises in movement amounts of movable support shafts at lower end sides of the respective crosslink mechanisms, converts the movement amount difference to an operating force of the operating lever at the larger movement amount side, and is such that by the operating lever at one side being driven by the link mechanism, the operating lever switches the ratchet pawl at the larger movement amount side to the engaged orientation.

An upstart motorcycle jack system that lifts a motorcycle from laying on its side to an upright position includes a scissor jack, a foot, a fulcrum pin, a mounting adaptor, and a motorcycle lift bracket. The motorcycle lift bracket is integrated onto the motorcycle. The foot is hingedly connected to a base pad of the scissor jack. The scissor jack pivotably mounts to the motorcycle lift bracket through the mounting adaptor and the fulcrum pin to initiate the lifting process. The mechanical leverage for the lifting process is provided by the scissor jack to lift the dead weight of the motorcycle pass a 45-degree angle. The scissor jack also transfers some of the motorcycle weight to the foot when the base pad starts to tilt toward the motorcycle. Once the scissor jack is fully extended, a rider can easily push the motorcycle back into the upright position.

A transportable drive-over conveyor system includes a drive-over hopper for receiving material and having a belt-type conveyor for conveying the material, a transition section pivotally connected at an upstream end to the drive-over hopper, an auger mounted at a downstream end of the transition section. The transition section transfers the material from the belt-type conveyor to the auger. The system may include radially offset wheels that support and move the conveyor system. The system further includes a pair of foldable ramps having hooks. The system further includes a folding and lifting mechanism which may include cables connected to the hooks for folding the foldable ramps and then lifting the conveyor system by the ramps.
