In the world of rigging, construction, and various industrial applications, wire rope clips stand as unassuming yet crucial components. Let's delve into the details of these essential fittings.​

What Are Wire Rope Clips?​

Wire rope clips, also known as cable clamps or U - clips, are used to fix the loose end of a loop back to the wire rope, or to join two wire rope ends together. They typically consist of a U - shaped bolt, a saddle (either forged or cast), and two nuts. This simple yet effective design allows for the creation of load - bearing eyes at the end of a cable or wire rope.​

Types of Wire Rope Clips​

Drop Forged Clips: These are the strongest type. The saddles in drop - forged clips are heated and hammered into shape, giving the steel a linear grain structure. This results in greater strength, making them ideal for important or critical applications, such as overhead lifting or suspending.​

Malleable Iron Clips: The saddles of malleable iron clips are cast into shape from a type of steel with poorer strength qualities compared to drop - forged steel. They have a granular microstructure, which means they can yield under greater loads. Thus, they are not suitable for overhead lifting but can be used in lighter - duty applications.​

Fist Grip Clips: These clips have a unique design with bolts and heavy hex nuts. They are easy to install as the operator can swing the wrench in a full arc each time. Unlike standard clips, they can be installed at any orientation relative to the live and dead ends of the wire rope.​

Materials Matter​

Stainless Steel: Stainless steel wire rope clips, especially those made of marine - grade 316 stainless steel, offer excellent corrosion - resistance. They are perfect for applications where exposure to the elements or corrosive substances is high, such as in marine environments. Type 304 stainless steel is also corrosion - resistant and suitable for more moderate conditions.​

Galvanized Steel: Galvanized wire rope clips provide a good balance between durability and affordability. The hot - dip galvanized saddles and electro - galvanized (zinc - plated) bolts and nuts resist rust, making them suitable for outdoor use in various applications.​

Zinc - Plated: Zinc - plated clamps are the most affordable option. However, they show signs of rusting more quickly than the other materials, so they are best suited for dry applications.​

Installation is Key​

Proper installation of wire rope clips is vital. Incorrect installation can reduce the working load limit by up to 40%. Here are some general guidelines:​

Always place the saddle on the live end of the wire rope. The U - bolt should rest on the dead end.​

Torque the nuts to the specified foot - pound rating.​

Use the correct number of clips as per the guidelines. For cable diameters 1/8” through 7/8”, a properly assembled wire rope clip termination can hold 80% of the breaking strength of the wire rope, while sizes 1” through 3 ½” have a termination efficiency of 90%.​

Versatile Applications​

Wire rope clips find applications in a wide range of industries:​

Construction: They are used to secure wire ropes in various construction projects, such as scaffolding, crane operations, and hoisting equipment.​

Marine: In the marine industry, they are used for rigging, mooring lines, and securing equipment on boats and ships.​

Industrial: From conveyor systems to machinery installations, wire rope clips play a crucial role in ensuring the safe and efficient operation of industrial equipment.​

In conclusion, wire rope clips may seem like simple components, but their importance cannot be overstated. Choosing the right type, material, and ensuring proper installation are essential for the success and safety of any project that involves wire ropes.​
