Wire ropes are one of the most versatile lifting and rigging equipment. But using them in different applications requires other rigging components like wire rope clamps. You will need to understand how to install wire rope cable clamps to ensure the safety and stability of a lift.
Also called wire rope clips, these clamps are metal devices used to fasten the ends of wire ropes together or secure the wire ropes to an anchor point. They typically consist of a U-shaped bolt, a saddle or plate, and two nuts.
The wire rope loop clamp gets placed in the saddle, and the U-bolt goes over the rope and is tightened with the nuts, securing the wire rope in place. You will use these clamps if you use wire ropes, making it necessary to know how to clamp wire rope.
Properly installed wire rope clamps can withstand significant tension and compression, making them ideal for use in several applications, including construction, mining, and transportation. As a leading wire rope clamp supplier, we know a thing or two about them.
Let’s learn about these clamps and how to clamp wire rope.
Types of Wire Rope Clamps
You must select the suitable wire rope loop clamp based on your application requirements. That said, there are different types of wire rope clamps. So, it’s best to understand each one to ensure proper and safe use.
1. U-Bolt Clamps
These wire rope clips are the most commonly used and consist of a U-bolt, saddle, and two nuts. They are usually made from forged steel or cast iron. They are easy to install and are suitable for most lifting and rigging applications.
2. Fist Grip Wire Rope Clips
As the name suggests, these wire rope loop clamps have a unique design that allows it to grip the wire rope tightly without causing damage to the wire rope. They consist of a saddle, U-bolt, and two nuts. Your wire rope clamp supplier will recommend them if you want a convenient and cost-effective solution.
3. Double Saddle Clamps
Double saddle clamps, or duplex wire rope clips, are designed for heavy-duty applications. They consist of two saddles, each with a leg and two nuts. While one gets placed on the top, the other goes on the bottom. They are more suited for applications where the wire rope has to withstand high loads or vibrations, such as in the construction, mining, and marine industries.
4. Simplex Wire Rope Clips
These wire rope clips typically consist of a single saddle with two holes and a U-shaped bolt. You can use them for light-duty applications, such as securing wire ropes in place or joining two wire ropes together. Simplex wire rope clips are easy to install and do not require special tools.
5. How to Clamp Wire Rope
Now that you have learned about different steel rope clamps, it’s time to know how to clamp them to a wire rope. You must know how to clamp wire rope to ensure the safety of your crew and the load.
Here are the steps that will tell you how to clamp wire rope in short.
1. Prepare the Wire Rope
First, prepare the wire rope for clamping. It’s easy. Remove any kinks or twists. Plus, ensure to cut the ends cleanly and squarely.
2. Insert the Wire Rope into the Clamps
Next, insert the wire rope into the clamps. Make sure to place the clamps in the correct position in the saddle of the clamp.
3. Tighten the Clamps
Now, tighten the clamps using a torque wrench, following the manufacturer’s recommended torque values. Be sure to tighten the nuts evenly. You can alternate between them to distribute the load evenly.
4. Inspect the Clamped Wire Rope
After tightening the clamps, inspect the clamped end of the wire rope. Ensure it is secure and free from any signs of damage, such as cracks or deformation. Also, check that the wire rope is correctly seated in the clamp and that the nuts are tight.
How to Install Wire Rope Cable Clamps
You will also need to know how to install wire rope cable clamps. This is a critical step in securing wire rope for various applications. Here are the steps to follow when installing wire rope cable clamps:
1. Determine the Number of Clamps Needed
This depends on the diameter of the wire rope and the type of clamp used. You will need to check the manufacturer’s recommendations or consult a wire rope expert to determine this.
2. Position the Clamps
Next, position the clamps on the wire rope per the manufacturer’s instructions. Making sure that the U-bolt is on the load-bearing side of the wire rope. Also, space the clamps evenly along the length of the wire rope.
3. Secure the Clamps
Tighten the nuts on the clamps using a torque wrench. Remember, you need to follow the manufacturer’s recommended torque values. Tighten the nuts evenly.
4. Inspect the Clamped Wire Rope
Lastly, check the clamped wire rope to see if it is secure and free from any signs of damage, such as cracks or deformation.
Wire Rope Clamp Safety Precautions
Only knowing how to install wire rope cable clamps isn’t enough. You will also need to consider a few safety precautions. As an experienced wire rope clamp supplier, we often recommend following safety measures.
1. Wear Protective Gear
Wear protective gear such as gloves and eye protection when installing or working with wire rope clamps. Talk to your wire rope clamp supplier if you need additional protection. They can set you up quickly.
2. Properly Position the Clamps
Improper positioning can lead to the failure of the clamp and the wire rope assembly. Keep the U-bolt on the load-bearing side of the rope.
3. Check Clamps for Tightness Regularly
The clamps will loosen with regular use. So, check the tightness of the clamps regularly, especially after the initial installation. They should be secure and free from any signs of wear or damage. If you see any damage, replace them immediately.
In Conclusion
If you use wire ropes in your daily rigging applications, you must’ve used wire rope clamps at some point. As a rigger or end user, you must know how to use, install, and replace them. You also need to understand how to use them safely. Hopefully, this post will help you in this regard.
