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;
• Precision of manufacturing: normal, increased (Т).
2. Ropes which breaking effort is specified to the right of the fat line are made of wire without coating.
3. Galvanized ropes of ОЖ group are made upon agreement.
4. The minimum rope length is 200 m.
5. Ropes of more than 16 tones are delivered on customer’s metal drums.
6. Recommended applications: mine elevating, digging road, elevating installations of an iron and steel industry.
