A tire lifting assembly used to remove and replace a wheel and a tire on a vehicle is disclosed. The tire lifting assembly is configured to take the weight of the wheel and the tire when the service technician removes or replaces it thereby eliminating the need for manual efforts from a service technician. The assembly is rolled under the mounted wheel and tire and quickly adjusted to secure the wheel and tire by using a roller platform. A scissor jack mechanism is used to adjust the height of the roller platform which allows the rotation of the tire during the mounting procedure.

The disclosure relates to a wheel dolly for vehicles, comprising wheels and two arms that are moveable towards one another, wherein the arms can be positioned laterally under a vehicle wheel, wherein the vehicle wheel can be lifted by moving the arms towards one another, wherein the arms can be moved towards one another using a lever. The arms can be moved towards one another by a mechanism which comprises a rod that can be moved step by step by virtue of a sliding member which engages around the rod, and which can be clamped using a stopping member.

A vehicle trolley device for mobilizing a vehicle with a flattened tire includes a ramp that comprises a field that is coupled to and extends between a pair of side supports. A plurality of wheels is coupled to a lower face of the ramp. The plurality of wheels is positioned proximate to a top end of the ramp. A plurality of fasteners is configurable to secure the ramp to the bottom of a flattened tire of a vehicle. The plurality of wheels is positioned on the ramp such that the ramp is configured for the user to position a vehicle that has a flattened tire onto the ramp. The ramp then is not in contact with the ground. The plurality of fasteners is configured to secure the flattened tire to the ramp, such that the user can drive the vehicle.

A portable powered roller assembly configured to impart a motive force to a wheeled vehicle or structure consists of a roller mounted in a rolling support structure. The roller is rotationally driven by a battery-powered drive unit coupled through a torque multiplying transmission, and is configured for engagement with the circumferential surface of a vehicle wheel. Rotational movement of the roller in engagement with the circumferential surface of the vehicle wheel draws the powered roller assembly towards, and under, the curved circumferential surface of the vehicle wheel, imparting a force to the vehicle wheel which include both a lifting force perpendicular to the supporting surface on which the powered roller is resting, and a motive force parallel to the surface.

A jack and dolly assembly and system including a shaft defining a longitudinal axis extending along the shaft and an interior hollow; a reversible drive mechanism at least partially positioned in the interior hollow of the shaft; a proximal arm removably secured to the shaft and substantially perpendicular to the longitudinal axis; a distal arm removably secured to the drive mechanism, the distal arm being spaced from and substantially parallel to the proximal arm; wherein the reversible drive mechanism is operable to move the distal arm along the shaft.

In at least one illustrative embodiment, a lift may comprise a support frame, a pair of lift arms pivotally coupled to the support frame and configured to support a motor vehicle tire, and a powertrain including a motor and a pair of pull rods, each of the pull rods being coupled between the motor and one of the pair of lift arms. The powertrain is operable to move the pair of lift arms between a first position, in which the second end of each of the lift arms is positioned a first distance above the support frame, and a second position, in which the second end of each of the lift arms is positioned a second distance above the support frame, the second distance being greater than the first distance.

A maneuvering jack for holding a wheel of a vehicle, in particular a motor vehicle. The maneuvering jack includes a base carrier, which comprises rolling elements in order to support the base carrier movably on an underlying surface; a lifting element, which is arranged on the base carrier and is provided for holding a wheel; at least one lifting device, which is designed to vary the height of the lifting element in relation to the base carrier; and at least one drive device, which is designed to drive at least one of the rolling elements in order to move the maneuvering jack on the underlying surface.
