An apparatus for removing lug nuts for changing a tire on a vehicle has a bracing structure and at least three arms connected to the bracing structure. A first arm extends upward and a second arm, adapted to operate as a footrest, extends outward and both arms are positioned such that one may stand on the second arm to generate extra torque while grasping the first arm for stability. A third arm is adapted to receive a socket and is oriented along the socket's axis of rotation. All arms are collapsible for storage.

A wheel lift comprises a frame having ground engaging elements, a four bar linkage structure supported by the frame, lifting arms extending from the four bar linkage and for receiving and supporting a wheel and a handle for operating the four bar linkage to raise and lower the wheel. The frame defines an open space for receiving a wheel, for example a vehicle wheel. The lifting arms may be raised and lowered and locked in position to aid in removing and/or mounting vehicle wheels.

A device is provided for changing a wheel of a vehicle comprising a carriage assembly including two platform elements running longitudinally with one another and substantially parallel. First and second swingarms are connected to respective platform elements. The swingarms are rotatably positionable at a desired height above the carriage. A lift mechanism selectively raises or lowers the carriage during use. A tow bar allows the carriage to be pushed or pulled on wheels mounted to the carriage. A method of the invention includes mounting the wheel on the platform elements, raising free ends of the swingarms to a desired height so a knock out bar may be placed through a hub of the wheel, operating the lift mechanism to raise the wheel to a desired height, and aligning the wheel with the vehicle so the wheel may be secured to the vehicle.

A socket spanner insert releases or fastens wheel bolts which in the mounted state rest inside wheel bolt holes of a car rim. The socket spanner insert includes a base body which has a screw head receptacle and a tool receptacle, and a sleeve which encompasses the base body at least in portions and is rotatably connected to the base body. In order to prevent damage to the rims when mounting and removing wheel bolts, a retaining element is provided which, during release or fastening of the wheel bolt, blocks a relative rotational movement of the sleeve with respect to the car rim and allows a rotation of the base body within the sleeve.

A lug wrench apparatus comprising a collet-type assembly whereby the socket clamps to the lug nut in a manner similar to the way a collet clamps a router bit. The clamping mechanism can be provided either by a screw-compression, or an eccentric cam compression. Arbitrarily large amounts of torque can be applied by means of an extension which fits over the arm of a wrench that is clamped to the shaft of the collet.

The embodied invention is a two tire lift tower and platform that is movable on castors. A motorized belt system is used to lift the tires. The belt system is mounted on each tower and is connected to a horizontal tire lifting bar. It is designed for portability by using a rechargeable battery is mounted on a rotating frame that allows each tire to be lifted separately. Simple buttons operate the tire belt lifting design that also allows for motor speed control to be adjusted by the operator. The dual belt system ensures that the horizontal lift bar is adequately maintained in a horizontal orientation. The maintenance of the unit is relatively simple due to the simplified design.
