Wire rope rigging hardware refers to the various components and fittings used in sailboat rigging systems that involve wire ropes. Wire rope is commonly used in standing rigging, such as shrouds and stays, due to its high strength and durability. Here are some examples of wire rope rigging hardware:
Swage Terminals: Swage terminals, also known as swage fittings, are fittings used to terminate wire rope ends. They are typically made of stainless steel and are attached to the wire rope by a swaging process, which involves compressing the fitting onto the wire rope using specialized tools or machinery. Swage terminals come in various shapes and sizes, including forks, eyes, studs, and toggles, to accommodate different rigging configurations.
Turnbuckles: Turnbuckles, mentioned earlier, are also commonly used in wire rope rigging. They allow for easy adjustment of tension in wire rope rigging systems. The turnbuckle body is connected to the wire rope using swage or mechanical fittings, while the threaded ends of the turnbuckle can be rotated to increase or relieve tension in the rigging.
Thimbles: Thimbles are metal or nylon inserts used to protect wire rope from wear and deformation when it makes a loop or eye. They help maintain the rope's strength and shape and prevent chafing or damage. Thimbles are typically placed inside the loop or eye of the wire rope and can be secured with swage sleeves or mechanical fittings.
Wire Rope Clips: Wire rope clips, also known as cable clamps or u-bolt clamps, are used to create a secure loop or eye in a wire rope. They consist of a u-shaped bolt and a saddle that sandwich the wire rope, with nuts threaded onto the u-bolt to tighten the assembly. Wire rope clips are commonly used in applications where a swage fitting is not practical or when temporary adjustments or repairs are needed.
Tensioners and Adjusters: Tensioners and adjusters are hardware components used to tension and adjust wire rope rigging. They can be mechanical devices or hydraulic systems that allow for precise control of tension in the wire rope. Tensioners and adjusters are often used in applications such as backstays or checkstays, where frequent adjustments are necessary.
Wire Rope Sheaves: Wire rope sheaves, also known as pulleys, are used to change the direction of the wire rope. They are typically mounted on blocks or fittings and allow the wire rope to run smoothly and efficiently. Wire rope sheaves can be made of various materials, including stainless steel or high-strength polymers, and are designed to withstand the loads and forces exerted by the rigging system.
These are just a few examples of wire rope rigging hardware used in sailboats. The specific hardware used will depend on the type and size of the sailboat, as well as its rigging configuration. It's important to consult with a professional rigger or refer to the sailboat manufacturer's guidelines for the appropriate selection and installation of wire rope rigging hardware for your specific sailboat.
