STRAND JACKS

STRAND JACK

FEATURES

The cylinders used for lifting by cables (Strand Jacks) are a compact and effective solution for the positioning of heavy loads operating both in load lifting and lowering.
The principle of operation is the same as post tensioning systems for pre cast concrete, using a bundle of cables (strands) which are pulled through wedge grips arranged both at the base of the
cylinder and at the rod end, passing through the central hole ofthe cylinder itself. You can then lift many metres with repeated strokes of the cylinder.
