A Better Designed Rolling Jack
The EZVJacks would be used in sets of two giving one for the back of the vehicle and one for the front. We settled on a boxed in welded unit cut with laser and CNC machining that could be adjusted with pins and without tools without compromising torque resistance strength. Thus no connection is needed between the ends of the arms of the rolling jack allowing excellent adjustability.
The wheel composition was also tested. The best all around wheel material I found was phenolic. It is inexpensive, resilient to fluids, is very light, is hard enough to have light rolling resistance, and is beveled so it swiveled easily. By making it 8 inches in diameter and 2 inches wide the capacity was very adequate at 1500 lbs. The height was decided on at 17 inches so it was within the lifting capacity of most hydraulic jacks but yet not too high to be unstable. It would bring the car up to a very easy level to work on and push against. The whole suspension or front or back of the car can be missing and the device can still support the remaining vehicle to allow it to be stored, worked on, or placed out of the way as parts are ordered.
I produced a prototype on my own cutting and welding as needed to make a device I could try out. Now it looks primitive, but my prototype worked even better than I thought it would and after using it for over 5 years I have been able to change the model slightly to make it a very usable finished product. Many improvements to this rolling jack have also been tested and incorporated.
