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. Galvanized ropes of OЖ group are made upon agreement.
4. The minimal rope length is 200 m.
5. Recommended applications are - digging road machines,   ship elevating installations.
