The most common cable construction is 1x19 type construction strand, which is 19 cables twisted in a single bundle, whereas for example, 7x7 would be 7 cable bundles of 7 cables twisted. This type of stainless strand is designed to have limited stretch, as compared to galvanized, [6] making it a good long term cable railing solution. It has ...
In stricter senses, the term wire rope refers to a diameter larger than 9.5 mm (3 ⁄ 8 in), with smaller gauges designated cable or cords. [1] Initially wrought iron wires were used, but today steel is the main material used for wire ropes. Historically, wire rope evolved from wrought iron chains, which had a record of mechanical failure.
Trapeze wires, which are narrow gauge flexible stainless steel wire, running from about the cross trees on the mast to the harness worn by a crew member and sometimes skipper on a high speed racing skiff. The lower section often has a system of small blocks which are used by the crew to alter the length of the trapeze wire as the crew moves aft ...
The principal element of this was a flexible tube (made from hard wound wire and fixed at each end) containing a length of fine wire rope that could slide within the tube, directly transmitting pulling, pushing or turning movements on the wire rope from one end to the other without the need of pulleys or flexible joints. The cable was ...
"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 ...
