ABSTRACT:
The present invention relates to a jacking system for use in the construction of buildings or other structures in which accurate control and synchronization of lifting points is required. The system is mainly used in lift-slab and lift-plate construction with permanent or removable columns and features an arrangement of converging control wires which activate sensing apparatus. The sensing apparatus controls hydraulic pumps placed at each or plural lifting points.
