STEEL WIRE ROPES
In crane market a wide variety of steel wire ropes are offered by their manufacturers. These are mostly categorized according to rope constructional style, load carrying capacity and core design either steel or fiber.

Today mainly more than 30 different types of steel wire ropes are recommended for different applications of industry. In mining, oil, elevators, aerial tramway, marina, fishing, ship, yacht, hoist, crane and general engineering industries mostly standard wire ropes are arranged from 160 kgf/mm2 (1570 N/mm2) up to 220 kgf/mm2 (2160 N/mm2) of loading capacities at 4 categories 160, 180, 200 and 220 kgf/mm2 and as a special type 250 kgf/mm2.

Steel wire ropes are very important in crane industry, since they are the start points when design. Bayursan as a standard prefers;

• 18x7 (126 single wires and one steel core) non turning (or so called nonflexible) wire ropes in its “CR” Class Royal series up to Ø16mm diameter and,
• 6x36 (216 single wires and one fiber core) Warrington Seale wire ropes up to Ø24mm diameter in its U series of higher capacities.

18x7 steel cored wire rope is quite tough and multilayered strands oppositely lay around its core and hardly be bended on its rope drum, so tends to be slack and skip to other grooves especially when no load on the hook. 18x7 wire rope though do not loosen in its groove under load nor turn to make windings nor deform one on another even at higher lifting heights. 18x7 wire rope thus can be used at smaller rope drum diameters respectively. These ropes generally last longer because of their constructional design and thicker wire sizes. Bayursan for the sake of its perfect and patented rope guide mechanism use these ropes

6x36 wire ropes are more elastic and have more carrying capacities respectively and preferred for heavier loads.
