Cross winding is reduced to approximately 20% of the circumference of the drum, and 80% remains parallel to the flanges in the inner layer rope groove. This parallel grooving evenly distributes the load between the individual layers and has been shown to increase substantially – by more than 500%, tests have shown – the life of the wire rope.

Steel wire rope (right hand lang lay) Wire rope is composed of as few as two solid, metal wires twisted into a helix that forms a composite rope, in a pattern known as laid rope. Larger diameter wire rope consists of multiple strands of such laid rope in a pattern known as cable laid. Manufactured using an industrial machine known as a strander ...
"Worming" the line is designed to fill in the channels (the contlines) between the strands in order to keep water out and to allow tighter, smoother wrapping of the next layers by giving the rope a more cylindrical shape. Lengths of "small stuff" or string are led along the lay of the rope between the strands, following the twist so that they ...
However, the rope and knotting expert Geoffrey Budworth warns against the practice of fusing thus: [2] Sealing rope ends this way is lazy and dangerous. A tugboat operator once sliced the palm of his hand open down to the sinews after the hardened (and obviously sharp) end of a rope that had been heat-sealed pulled through his grasp. There is ...
The eye splice is a method of creating a permanent loop (an "eye") in the end of a rope by means of rope splicing. The Flemish eye is a type of circular loop at the end of a thread. There are several techniques of creating the eye with its knot tied back to the line, rope or wire.
Over the K&T era multiple wire types evolved. Early wiring was insulated with cotton cloth and soft rubber, while later wiring was much more robust. Although the actual wire covering may have degraded over the decades, the porcelain standoffs have a nearly unlimited lifespan and will keep any bare wires safely insulated.
Rope drive in a hydroelectric plant Multiple rope drives driving lineshafts on each factory floor. The rope drives were placed in a large diagonal shaft at the side of the building, usually windowless and distinctively visible from outside the building. [ii] Rope drives required a larger such shaft than comparable belt or shaft drives.
