Following points are important in the mining ropes operating for heavy-duty purposes,
Resistance to abrasion.
Resistance to bending.
Resistance to crashing.
Resistance to corrosion.
Compositions with parallel wires in which wires in strands are at same step and with steel core is generally preferred.
Rope wires are in at least 180 kg/mm2 resistance value. Ropes may be manufactured as uncoated lubricated or galvanized lubricated. Ropes with 8 strands may be used when elasticity and resistance are in same importance.
Places of Use
They are used in mining as drag and lifting ropes, elevator ropes in Koepe system and every kind of load lifting, landing and gripping ropes.
