wire rope clamp position free sample

While these clips are not designed to be used in an overhead lifting situation (swage sleeves should be used instead), wire rope clips are heavy-duty wire rope clips that used for sustaining overhead loads. Examples include guy lines, support lines, scaffolding, etc.

Install the first clip at the dead end side of the rope. The "U" side of the clip must always cover the dead end of the rope, and the "saddle" side of the clip on the live end of the rope. Place the nuts of the clip and tighten them using a torque wrench.

Place more clips on the rope if you need more than two on the wire rope. Be sure to space them evenly between the end clips. Finally, tighten the end clips and apply tension to reach the recommended torque for the wire rope.

Wire Rope Clip a.k.a Bulldog Clip or U-Bolt Clip which used to clamp the loose end of wire rope by looping the wire rope back and form eye to create a bearing point. The termination efficiency of forged wire rope clip shall be 80%.

According to EN 13411-5, grip secured eye termination wire rope is only suitable in suspending static load and single use lifting operation (one time use lifting operation with proper safetyfactor consideration). To use with spiral rope or use it in general lifting sling make is not recommended.

Proper secure of wire rope clip, the distance, d between wire rope clip and the distance of wire rope clip to tail have to be at least 1.5 times and not more than 3 times of the wire rope clip base width. Collar nut shall be secured with proper torque value according to size of the wire rope clip to prevent crushing the wire rope if the torque value is too large or wire rope slip over uf the torque value is below the proper or recommended collar nut pre-load value.

The number of malleable wire rope clip used in securing eye termination shall be one more than the forged wire rope clip used in same size of wire rope.

Proof load value of Grip Secured eye termination shall is 20% of the wire rope Minimum Breaking Strength, the collar nut needs to be re-torque to proper value after the proof load testing.

Wire rope is an extremely versatile mechanical device that can be used to help support and move an object or load. Whether for use on cranes or for other lifting applications, it’s important to have a solid understanding of the rigging components that are being used to attach to and lift a load.

As a rigger or end-user of wire rope, it’s necessary to understand the types of wire rope end termination, or treatments that can be used at the ends of a length of wire rope—one of the most common being wire rope clips.

Wire rope clips can be used to form a load bearing eye at the end of a cable or wire rope, or to connect two cables together with a lap splice. Wire rope clips are popular because they can be installed in the field and provide 80-90% efficiency of the rope breaking strength, depending on the diameter of the wire rope.

As a general guideline, they are NOT to be used for making slings, as ASME B30.9 Slingsstandard states: “Mechanical wire rope terminations requiring periodic adjustment to maintain efficiency shall not be used to fabricate slings.”

There are two main types of wire rope clips—U-Bolt and double saddle clips. U-Bolt wire rope clips are the most common and may be made of forged or malleable metal.

This type of wire rope clip is essentially a U-bolt, two nuts, and a metal base (saddle) that can be made from forged steel or cast iron. Careful consideration and attention must be given to the way U-bolt type wire rope clips are installed.

The base of the wire rope clip is made from forged steel. Forged clips are heated and hammered into the desired shape—resulting in a consistent grain structure in the steel. Forged wire rope clips are used for critical, heavy-duty, overhead loads such as winch lines, crane hoist lines, support lines, guy lines, towing lines, tie downs, scaffolds, etc.

Malleable wire rope clips are used for making eye termination assemblies only with right regular lay wire rope and only for light duty uses with small applied loads, such as hand rails, fencing, guard rails, etc. The base of the wire rope clips is made from malleable cast iron, which may fracture under heavy use and does not have the desirable metal properties of steel, or the beneficial grain structure that a forged base has.

Unfortunately, it is not uncommon to see a wire rope clip applied incorrectly. Some of the most common mistakes include:Not torquing to the manufacturer’s expectations

Wire rope clips require the use of a torque wrench in order to function properly. Torquing the nuts on the clips too much or too little can cause the clip to fail. If the clip is over-torqued, it could damage the threads of the wire rope. If the clip is under-torqued, the holding power of the clip is diminished and the wire rope could slip through.

There are a minimum number of clips required for use related to the wire rope diameter. Using less than the number of specified clips could result in decreased efficiency and possible failure.

Depending on the number and size of the wire rope clips, there is a proportional amount of space required between the placement on each clip on the rope.

There are two sides of a U-Bolt style wire rope clip: the saddle and the U-Bolt. When securing a wire rope eye, it is important to place the clip on the correct end of the rope.

A saying commonly used in rigging to help remember this is: “Never saddle a dead horse!” In other words, never put the saddle on the dead end of the rope.

The turnback is the portion of the wire rope eye that runs from the end of the bearing eye to the live end. Having less than the suggested amount of turnback will decrease the efficiency of the wire rope eye and could lead to failure.

It is important to be sure you are using the correct wire rope clip—forged or malleable wire rope clips—for the application. Malleable clips can only be used for non-critical uses, such as tension rope to form a perimeter around a parking lot.

If the use is critical—an application where, if there is a failure, you have potential injury or loss of life or damage to property—a forged clip must be used.

The clip size used—whether it be 1/8”, 3”, or otherwise—must match the diameter size of the wire rope. If it doesn’t, the wire rope could slip out of the clip.

After installing clips, it is necessary to regularly cycle the rope and retighten the clips. Monitoring the torque on the nuts is important, as they will loosen over repeated use.

Basic steps for installing a wire rope clip include:First, wrap the wire rope around the thimble or to form the eye, and turn back the correct amount of rope—as specified by the manufacturer.

Apply the first wire rope clip at the end of the dead end, with one base width of space. Use a torque wrench to tighten the nuts on the wire rope clip.

When applying the second clip (if required), place it as close to the eye loop or thimble as possible. Again, be sure to properly tighten the nuts of the clip with a torque wrench.

Wire rope clips are a common and necessary piece of rigging hardware when it comes to using wire rope and forming end terminations. They are used to form a wire rope eye or to connect two cables together. It’s important to understand how to correctly install a wire rope clip, as incorrect installation leads to decreased efficiency in the wire rope assembly.

Murphy offers many sizes of wire rope clips in 4 different fabrications: zinc plated, stainless steel malleable, galvanized drop forged, and stainless steel drop forged.

You can use wire cable clips to secure the loose ends of your wire ropes. They often have nuts, u-shaped bolts, and cast saddles. You can put the wire rope in the bolt and then place the saddle over the bolt’s rope. By using the nuts, you can then secure the rope in its place.

There are a couple of ways to make the process stronger. For example, if you have a cable coated with vinyl, then you can take off the vinyl in the place where you put it in the wire rope clip.

We offer our clips in a range of materials, which gives you more options. You can use the clips for semi-permanent or permanent applications, or just temporary ones. You can use your hand tools to secure them to your stainless steel wire rope. They are also cost-effective.

Wire ropes are one of the most critical pieces of rigging and lifting hardware. You can use wire ropes for lifting, rigging, and tying loads of virtually any size, shape, and type. To make the most out of wire ropes, however, you need a few additional rigging equipment, one of which includes wire rope clamps.

Also known as wire rope clips, riggers often use this nifty little piece of hardware at the end of the length of a wire rope. You can use a wire rope clamp to:

In short, a cable clamp is what makes a wire rope one of the most versatile pieces of rigging hardware. As these clamps come in different shapes, sizes, and materials, you will need to choose one that perfectly fits your lifting and rigging application. But before we get down to that, first, you need to understand what is wire rope clamp, its types, and a few other things.

It is a simple mechanical device. A typical wire rope clip consists of a saddle, U-bolt, and two hex nuts. This simple device is suitable for less permanent rigging and lifting applications. You must never use wire rope clips to make industrial slings.

The ASME B30.9 Slings standard clearly states that riggers should not use mechanical wire rope terminations that require periodic adjustments to create slings. In other words, you need to be careful when using rope clamps. You can use a wire rope clip to create an end loop for a winching or crane cable. You can also use it to build perimeter cables or increase the length of a wire rope going through a D-shackle or eye bolt.

Based on their shape, there are two types of cable clamps, U-bolt and double saddle. They both have unique mechanical properties and hence applications.

These cable clamps consist of a U-bolt, two nuts, and a metal base called a saddle. The U-bold passes through the saddle, which you can tighten with the two nuts. They come in various sizes and types of materials, including stainless steel and galvanized steel. You can choose a U-bolt wire rope clamp depending on your rigging or lifting application.

Usually, there are three types of materials used for making rope clips. You can choose a material based on your application as each one comes with its unique strengths and weaknesses.

In this type of wire rope clip, the base or saddle is made from forged steel. The manufacturing process involves heating and hammering the clips into desired shapes. Riggers often use these cable clamps for critical and heavy-duty applications as they are very strong. You can see them in winch lines, crane cables, hoist lines, towing lines, scaffoldings, guy lines, and even tie-downs.

The base or saddle is made from cast iron. As cast iron lacks the metal properties of stainless steel, it is not that strong. So, the malleable galvanized wire rope clamps are not very strong. They can break under heavy usage. You will see them being used in small or light-duty applications like fencing, parameter cables, or guard rails.

Stainless steel wire rope clips are arguably the best ones. The base or saddle is made from high tensile strength stainless steel. They are durable and easy to use. You can find these cable clamps in temporary guard rails, flag posts, and other outdoor rigging applications.

Wire rope clamps are an essential part of the rigging hardware. You can’t do away with them. But you have to make sure to use the right ones to keep the load and the riggers safe. If a wire rope snaps because you used the wrong type of clip, it can lead to disastrous consequences.

The first step in choosing cable clamps is to buy them from a trusted and reputed rigging hardware manufacturer. The last thing you want is to use a defective or poor-quality clip. This will compromise the safety of your load and your crew.

As you can see, each wire rope clamp comes with unique properties. You need the instruction manual to understand when, where, and how to use the cable clamps. Make sure the clamps are accompanied by respective user manuals when making a purchase.

By now, you know that some cable clamps are more suited for outdoor environments, while others aren’t. As a result, carefully think about where you want to use the wire rope clips. For example, if it’s a heavy outdoor application, stainless steel wire rope clamps would be a great fit.

Taking into account how large and heavy the load is also equally important. Heavier loads will require strong cable clamps that won’t break under stress. Also, you shouldn’t use clips for any permanent rigging or lifting applications. They are suited only for temporary load applications.

Lastly, it’s always better to get an expert on board when shopping for wire rope clips. Maybe you can hire an engineer or expert with considerable field experience to help you choose the right types of clamps. An expert will help you take every detail into account before making the purchase. Remember, if you choose the right cable clamps right off the bat, you’ll save considerable time and money down the line.

Wire rope clamps are one of the essential rigging hardware. They land wire ropes more flexibility, allowing you to handle a wide range of applications with ease and safety. These are some tips that will help you choose the appropriate clamp for your need.

The present invention relates to a wire rope clip. In particular, the present invention is directed to a two-piece bolt and saddle for wire rope clips, which will grip and secure to the exterior surface of a rope or cable.

Previously existing wire rope clips have been forged and comprised of two identical clamps, each having a long threaded leg and an orifice for receiving a threaded leg of the corresponding clamp. The forged pieces were designed to be assembled together for clamping a wire rope. An example of such a wire rope clip is a FIST GRIP® clip manufactured by The Crosby Group, Inc.

Another example of a wire rope clamp is shown in U.S. Pat. No. 3,333,303 to St. Pierre. The St. Pierre wire rope clamp is constructed of two identical forgings secured together by a pair of conventional bolts. The St. Pierre wire rope clamp eliminates the need to forge a long leg on the clamps by replacing the leg with a standard bolt that passes through apertures formed within the clamps. The clamps are provided with a sunken hexhead socket for making the bolt heads non-rotatable. Although the sunken hexhead provided on the forged piece prevents rotation of the bolt, the sunken hexhead does not secure the bolts within the apertures of the unassembled clamps. Since the bolts are free to slide in or out of a clamp, difficulties arise in assembling the completed wire rope clamp.

It is an additional object to provide a wire rope clamp wherein a bolt is non-rotatable and is removably secured in a respective saddle so that the wire rope saddle may be assembled with greater ease without the difficulties associated with unintentional bolt disengagement from the saddle.

The wire rope clip of the present invention includes a first and second bolt each having a head, a threaded end and a plurality of splines. The splines are fashioned on the bolts proximate the head. The first bolt is received in a first orifice fashioned in a first saddle. The second bolt is received in a first orifice fashioned in a second saddle. The bolts are preferably press fit into the orifices whereby the splines on the bolts engage the walls of the first orifices so that the bolts are removably secured therein. The splines not only prevent rotation of the bolts, but also keep the bolts secured into their respective saddles.

Additionally, each saddle has a second orifice fashioned therein. The second orifice of the first saddle is for receiving the threaded end of the second bolt. The second orifice of the second saddle is for receiving the threaded end of the first bolt. The saddles are secured together by means of a first nut and a second nut that bias against the base of the second saddle and the base of the first saddle, respectively. Both the first saddle and the second saddle have a rope engaging surface fashioned between their respective first orifice and second orifice. Each rope engaging surface is fashioned on the surface opposite the base of each saddle. The wire rope clip is preferably constructed such that the first orifice on the first and second saddles are provided with a chamfered recess proximate the base of each respective saddle for receiving bolts having countersunk heads. By constructing the wire rope clip in this manner, the heads of the first and second bolts are flush with the base of the first and second saddles.

By constructing the two identical saddles, and securing the saddles together by means of the first bolt and the second bolt, a wire rope may be securely clamped by the wire rope clip.

Referring to the drawings in detail. FIG. 1 illustrates a preferred embodiment of first saddle 10 and first bolt 12 of the wire rope clip. First saddle 10 is provided with first orifice 14 and second orifice 16. Additionally, first saddle 10 is provided with rope engaging surface 18 and base 20 formed on an opposite side thereof.

Referring to FIG. 2, an exploded side elevation view of a wire rope clip is provided. First saddle 10 is shown with first bolt 12 affixed thereto. First bolt 12 preferably is press fit within first orifice 14. It is noted that chamfered recess 22 receives countersunk head 24 as shown in FIG. 1, thereby resulting in flush surface 32. Opposite first saddle 10 is second saddle 34. Second saddle 34 is shown with second bolt 36 affixed thereto. Second bolt 36 is preferably press fit within first orifice 38 formed in second saddle 34. Additionally, second orifice 40 is provided in second saddle 34.

Second saddle 34 is provided with rope engaging surface 42 on one side and base 44 on an opposite side. Similar to first saddle 10, second saddle 34 also has a chamfered recess for receiving a countersunk head of second bolt 36. Second bolt 36 includes a threaded end 46 and splines or ribs, similar to first bolt 12. The union of the chamfered recess of second saddle 34 and the corresponding countersunk head of second bolt 36 result in flush surface 48 on base 44 of second saddle 34.

Threaded end 26 of first bolt 12 passes through second orifice 40 of second saddle 34 and engages first nut 50. Similarly, threaded end 46 of second bolt 36 passes through second orifice 16 of first saddle 10 for engaging second nut 52. First nut 50 biases against base 44 of second saddle 34 and second nut 52 biases against base 20 of first saddle 10. Therefore, rope engaging surface 18 of first saddle 10 is positioned opposite rope engaging surface 42 of second saddle 34. Rope engaging surfaces 18 and 42 are designed to engage a wire or other type of rope therebetween to secure the rope therein.

By utilizing the wire rope clip of the invention, first nut 50 and second nut 52 can be installed in such a way as to enable an operator to swing a wrench in a full arc for fast installation.

First saddle 10 is positioned such that rope engaging surface 18 engages a wire rope and positions second saddle 34 such that threaded end 26 of first bolt 12 passes through second orifice 40 of second saddle 34. Additionally, second saddle 34 is positioned such that rope engaging surface 42 also engages a wire rope. First nut 50 is then threaded over threaded end 26 of first bolt 12 and second nut 52 is threaded onto threaded end 46 of second bolt 36. In this manner, two pieces of wire rope may be securely clamped by the wire rope clip of the present invention.

The wire rope clips may be utilized on turnback loops formed from a single piece of cable or to splice two pieces of wire rope together. It is to be understood that the wire rope clips may also be utilized for other applications where traditional wire rope clips have been utilized.
