NOTES:

  1. Ropes are produced according to:
    • Application-for people and cargoes (ГЛ), 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 direction: right and left (Л);
    • 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 applications: for lifts, various hoists, on skip domain rise, on timber rafting.
