Wire stretching pulleys, one for each wire, rotate on bearings and are individually driven by a single hydraulic piston ensuring a uniform and constant tension of each wire; this is essential to prevent wires from being less tensioned, which would reduce the down-feed speed. The arc of movement of the wire stretching pulleys is very large, therefore the wire installation is very easy and any complicated prestretching system has been eliminated.
The staircase and gangway system allows an easy, quick and safe installation of wires.
Both idle and motorized rollers are easily accessible and protected by a sliding guard.
