The multilayer wire rope spooling system has undergone continuous refinement over the years and adapted for any application where long lengths of steel wire ropes must be wrapped in multiple layers quickly and smoothly. Examples include: Cranes for construction sites, offshore oil rigs, ports or on board ships; Deep mining
Sheave – Grooved wheel used to support a moving belt, wire or rope; Sheer legs; Sling (rigging) – Rope, webbing, wire or chain used to support a load for lifting; Rope splicing – Semi-permanent joint between two ropes; Tackle – System of two or more pulleys and a rope or cable; Tirfor – Device for pulling cable; Tugger (rigging)
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.
It is attached securely to a stationary object directly by a locking device or indirectly via a rope, cable, or webbing and one or more locking devices. Some safety harnesses are used in combination with a shock-absorbing lanyard, which is used to regulate deceleration and thereby prevent a serious G-force injury when the end of the rope is ...
When a vehicle impacts the low-tension system under normal conditions, the cable moves as much as 12 ft (3.7 metres) from its original location. This movement is known as the dynamic deflection. Given the lack of tension in the system, individual installations, or “runs”, of cable are limited to 2,000 ft (600 metres) with an anchor assembly ...
A towing sock or wire rope puller or wire pulling grip is a device that connects to the end of a cable, such as a power cable, in order to pull it through a tube or tunnel. [1] It works by tightening around the cable when pulled, in the same manner as a Chinese finger trap . [ 2 ]

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 ...
