GCR Eurodraw: PC wire and PC strand automated threading systems

GCR Eurodraw has designed a system to automate the threading of the double capstans on PC wire and PC strand lines. The system allows theading of the line in a very quick and safe way. In case of wire breaks or when changing diameter of wire, the system allows to rethread the line in a matter of just a few minutes and with a single operator.

The unit consists of a motorized trolley equipped with a clamp. The trolley runs on a track that has the shape of the two capstans. The trolley moves around the track several times laying the wire into the capstan grooves. Once all groves are full, the trolley stops and the operator can take the wire to the pinch rolls or the spooler.

This system can be fitted on all new lines and on existing lines of any manufacturer.




PC strand is used as a reinforcement product for concrete beams and precast concrete structures. It is a high carbon product that is composed by 7 wires that are stranded together and then stretched ad heat treated in order to obtain the low relaxation property.

  PC wire is a similar product of PC strand but it is composed of a single wire. The production process differs only by the fact that there is no stranding.  PC wire is used as a reinforcement of concrete railroad tiles and can be supplied in coils or pre cut  and threaded bars. In this case as well the heat treatment is performed by an induction furnace that can be sized up to 650 kW in power.
