ABSTRACT:
A construction system incorporating the formation of a plurality of building components, such as but not limited to concrete slabs used for floors, wherein the slabs are formed about a plurality of supporting columns of a predetermined height depending upon the intended height of the building under construction. The subject system includes a plurality of lifting assemblies secured to the slabs, and structured to travel along the length of the columns carrying the slabs as they travel. A control assembly is provided to insure a level orientation of the slabs and a consistent rate of travel and lifting force being exerted on the slabs uniformly so as to maintain such slabs, during lifting, in a level orientation to prevent damage thereto.
