Abstract
A jack stand apparatus has a frame having a first portion and an outwardly extending second portion, a barrel affixed to the outwardly extending portion so as to have a generally vertical longitudinal axis, a jack screw threadedly received by the barrel, and a plurality of caster wheels removably affixed to the frame. The barrel has an outer end extending outwardly for a first distance from the first portion of the frame. The plurality of caster wheels support the frame for a second distance from a level of the bottom of the caster wheels. The first distance is no more than the second distance. A support head is affixed to an end of the jack screw opposite the barrel. The frame is invertible relative to the caster wheels such that in one position the barrel extends upwardly from the frame and a second position in which the barrel extends downwardly from the frame.
