Sewed Flat Ropes - Steel Wire, 6-10 Lines, Left/right Lay | No Twisting, Mass Variability, Low Diameter Loop, Easy Fitting

Sewed Flat Ropes

Such ropes consist usually of 6,8 or 10 independent lines (each line consists of four strands) with either left or right direction of lay, which are located one opposite to another and keep in place by wires, strands or rivets.

In practice, flat sewed ropes are rarely used when compare to other steel wire ropes.

As non-rotating ropes they are used in bobbin drives of shaft hoists for sinking, as rescue hoists and as balance ropes in mining shaft hoists with friction drives.

Flat ropes are characterized by specific properties which make them different to other constructions:

Their most important advantages:

- lack of twisting moment,

- high variability of mass density it facilitates selection of rope to mining hoisting equipment,

- low diameter of reverse loop,

- easy and strong fitting at hanging hoisting vessels.

Main reason of these ropes wear is corrosion. The only control method is visual evaluation.

Flat sewed ropes are characterized by high cost of production (manual sewing partially mechanized).
