Heavy Duty Safety Stand Plans

[Frank S]

The plans list both the 3 and the 4 leg stands. these are tall stands mainly designed for heavy vehicles the height range is from 19" (480mm) to 26" (660MM) nominal
There are both advantages and disadvantages to any design.
On the one hand a 3 leg stand will sometimes allow for placement closer to the backing plat on trucks while depending on how a stand is situated under a vehicle the 4 leg stand provides slightly more stable support. as with any supporting device care must be taken when using in the elevated heights, just because a device will support a given amount of weight without structural failure does not negate the possibility of the supported vehicle shifting.
I have plans to produce a reduced height set of plans for those who require shorter stands However with these plans the fabricator should be able to scale them down for their needs as long as they maintain the material thickness and relative size dimensions just shorten the legs main tube and the inner tube lengths. I do not recommend increasing the height due to possible loss of stability
