NOTES:

1. Ropes are produced according to:
• Application - For cargos (Г);
• Wire   mechanical properties:    of BK mark - high quality; of B mark  -increased quality, of mark 1 - normal quality;
• Wire surface coating: without coating, with  zinc coating;
• Lay type: untwisted (H), twisted;
• Precision of manufacturing: normal, increased (T).
2. Ropes, which breaking effort is specified to the right of a fat   line, are made of a wire without coating.
3. The minimal rope length is 200 m.
4. Recommended for application as cargo ropes on minor lifts.
