Transporter for slab casting tables

A mobile transporter for use in transporting equipment during the construction of a building, said transporter comprising a lower section supported on ground engaging means for movement thereon, a mast supported within said lower section for vertical movement relative to said lower section, and an upper frame supported on the upper end of said mast, wherein the lower end of said mast rigidly carries a ground engaging support structure, lifting means located exterior of said mast and interconnected between the support structure and said lower section and, being free of direct connection to said mast, for, in use, lowering and raising said mast and support structure between a position wherein said lower section is supported on said ground engaging means and a position whereby said support structure is moved to a ground engaging position for subsequently lifting said lower section and its ground engaging means off the ground whereby said lower section is supported on said support structure, means cooperating with said mast and support structure and said lower section for achieving relative rotating movement between said lower section and said mast, and wherein said upper frame carries a horizontally slidable carriage adapted, in use, to supportingly engage beneath a load to be transported thereon, and means are provided to move said carriage between extended and retracted positions relative to said upper frame.
