Winding & Re-reeling steel wire ropes

It is important to attach steel wire ropes at the correct locations on a smooth drum as improper winding methods will cause the spreading of terns in the first layer of steel wire ropes on the drum. Then the second layer of wire ropes may be wedged between the open coils of first layer, crushing and flattening the rope as successive layers are spooled.

Generally, steel wire ropes are wound from the top of the one reel to the top of another or from the bottom to bottom. But how to start wire ropes on a drum may puzzle lots of our customers. The following illustration will give you the best solution.
