Hydraulic Jacking Systems with capacity up to 1000 tons.
A number of strands – steel wires – arranged circumferentially passes through a hydraulic cylinder jack with anchors at both ends of the jack. The anchors have grips which alternatively grip and release the strands. The strand jack is positioned on a support beam vertically on top of the location to where the load has to be lifted. The load is connected to the strands by a suitable block.
