NOTES:

  1. Ropes are produced according to:
    • Application: for people and cargoes (ГЛ), for cargoes (Г);
    • Wire mechanical properties:  of BK mark — height quality, of  В mark — increased quality, of mark 1 — normal quality;
    • Wire surface coating : without coating, with zinc coating;
    • Lay direction: right, left (Л);
    • Lay Type: untwisted (Н), twisted;
  2. Ropes of galvanized wire with C covering group of marking groups 1180 (120), 1270 (130) twisted (P) ropes are made serially; of higher marking groups are produced on agreement.
  3. Ropes of 1470 (150) and higher marking groups as well as wire ropes with zinc covering on Ж group are made upon agreement.
  4. The minimum rope length is 200 m.
  5. Recommended applications: on pendant rope roads and cables- cranes as bearing ropes, walking excavator and at building of various technical constructions as guys.
