NOTES:

1. Ropes are produced according to:
• Wire mechanical properties: of BK mark — height 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.
