A permanently mounted pneumatic jack (jacklift) system for motor vehicles, as well as an impact wrench for removing and installing lug nuts. The system provides a quick and safe means of lifting one or more tires off the ground for replacement of a spare or rotating the tires on a motor vehicle. The present invention comprises two or more (typically four) pneumatic jacks, a system ON/OFF switch, an air compressor, a 120-psi air tank, air lines (hoses), individual jack extend/retract switches, jack position-locking pins, safety-locking pins, and impact wrench. Each jack can be locked in a horizontal stowaway or vertical operational position. The jack is cylindrical shaped with a telescopic body that can be extended or retracted as needed to raise and lower the vehicle. A solid cylindrical lift rod slides inside a cylindrical outer housing with a high-pressure seal means used to maintain pressure on the support rod. A ground support foot (plate) is mounted on the lower end of the solid cylindrical lift rod to provide sufficient traction with the ground to support the lifting process. A quick release air coupler is included on the pneumatic chamber to support the use of an air hose and impact wrench. An extend/retract toggle switch is included on each jack to control a solenoid valve to allow the air to flow into the jack. A quick release safety-locking pin is used to mechanically pin the solid cylindrical lift rod to the outer housing once the desired height is achieved to assure that the vehicle does not fall down in the event of a high-pressure air loss, thereby providing safety to the person(s) working around the vehicle. An air compressor located in the engine compartment of the vehicle is mechanically belt-driven off the engine. A high-pressure air line carries the air to a high-pressure (at least 120-psi) air tank located in the trunk or other suitable storage area on the vehicle. Separate air lines extend from the air tank to the individual jacks.

In use, the nose centers both the lug nut relative to the wheel bolt it receives and the wheel relative to the axle hub. The laminated nut includes a plurality of conical disc springs enclosed in a cage. When properly tightened, the disc springs deform to impart additional gripping force on the wheel bolt. Accordingly, the laminated nut provides additional resistance to loosening, even when used with a non-ferrous wheel. In one embodiment, the nose is attached to the cage, for example, by snap-fitting onto the base of the cage. The wheel lug nut may also include a removable decorative cap that encloses and protects the cage and the wheel bolt. The decorative cap may be removably attached to the nose.

A method and apparatus for plating parts like lug nuts or other metal parts that have both an easily plated outside surface as well as a recessed cavity. The invention works in combination with a standard multi-station plating process. Also, a method and apparatus for preventing areas of electrode contact on a part from being non-plated. The present invention drains and plates a part containing a cavity by moving the part from a position where the cavity is facing around 45 degrees down to a position where the cavity is facing around 45 degrees up and then back down at various times during the process. The moving is generally initiated when the rack moving along a track above the fluid tanks encounters a roller. The roller causes a depression bar to activate a mechanical mechanism that shifts the position of the part. Other embodiments of the present invention can also rotate the part on an electrode finger as a roller on the track is encountered by the rack to avoid non-plated regions on the part.
