Steel frame posts are uprightly secured by an apparatus having a stable, wide access platform with X-Y adjusters for adjusting the position of the steel frame posts while the posts are temporarily supported. The access platform has wheels to travel by itself along a pair of rails. The X-Y adjusters are disposed at an edge of the access platform and are composed of a longitudinal slide and a transverse slide, which are provided on a fixed base and are slid to a suitable position for permanent bolting of the steel frame posts by easy controls in use of respective feeding handles. A coupler connected to the steel frame post by a vice is coupled with a protruding bar provided at a top of the X-Y adjuster for temporarily holding the steel frame post.
