ropes are built up with bright and zinc-plated steel wires pleached round textile and
metallic cores. The diameters, extimated on the section of new ropes, have a tollerance of
+/- 5% fore the ropes with the cright wires and of +/- 2% or +/- 8% for those ones with
zinc-plated wires. The theoretic weights per linear metre are estimed on the basis of the
metallic surface of the rope, excluding the possible greasing. The breaking load is
determined by the wires section compared to their resistence, talking also into
consideration the stranding coefficent, varyng in relation to the type of the rope. Sirio
System pots at its clientele's disposal also the tie-rods, the more suitable ones in
dimension and lenght, together with the ropes-blocking realized with the staking system or
with pressed sleeves. |
