Wire rope sling
Tips for making a steel cable sling with a pressing clamp.
Tools required:
Press sleeves
Steel cable
Pressing clamp
Steel cable cutter
Gloves and safety goggles if required
Make sure the cable is clean.
Leave the purchased cable on the reel. Before we make the loop on the cable, we first check whether the cable has been cut tightly. When cutting, it is important that the cable is straight, round and without protrusions. A special steel cable cutter has a round jaw and ensures that the cable remains round after cutting.
Tip: If you cannot cut the cable properly, use adhesive tape around the cable. Then cut the cable in the middle of the tape. This is particularly useful for thinner steel wire rope.
Which cable will you use to make the loop?
Galvanized: Galvanized is the most common. Galvanised steel wire rope is inexpensive and easy to process. The galvanised cable has a galvanised layer so it will not rust quickly. The crimping clamp that is most often used with this cable is the aluminium crimping clamp.
Plasticised: In addition to galvanised cable, it is also possible to use plasticised or coated cable. These are easy to handle because the outside is coated. An aluminium press sleeve can also be used for this cable. The outer dimensions should be taken into account.
Stainless steel: Stainless steel wire rope is the most weather-resistant and visually appealing cable. Stainless steel is harder than galvanised steel and is therefore more difficult to process. The copper or stainless steel crimping clamp is the best solution for this cable.
Size determination:
With crimping sleeves the diameter of the cable is always used. This can sometimes be confusing because the cable can go in twice. For example: You have 3mm steel cable, which also requires a 3mm crimping sleeve.
Making the loop
Thread the cable through the crimping sleeve. If you want several sleeves on 1 loop, you can slide the extra ones on. When they are in place, the cable can be put back into the crimping sleeve.
It is now possible to place a sleeving. This protects the cable and makes the whole stronger, ensuring that the forces are distributed.
Use a pressing tool.
When clamping 1 to 2 mm, use the pressing tool ST001, which is easy to use with one hand. When the clamp is fully pressed, the pliers open automatically.
When clamping cables of 2 to 5mm use Crimping Pliers 18500TN. Place the wire clamp or ferrule vertically in the jaws of the pliers. The jaw that best encloses the crimping clip is the appropriate one for making the press. Then you can pull the handles fully together. And the press is made.
Frequently asked questions
Question: I cannot get the steel cable in. What do I do now?
Answer: First insert the cable through the press sleeve. Pull the cable through a bit. Then put the cable back in again.
Question: Can't I just use aluminium wire clamps for stainless steel?
Answer: The press will do just fine. But if it hangs outside a little longer, and this is accelerated by salt water and extreme weather conditions. This gives a reaction to the aluminium. This weakens your press.
Question: What size ferrule or wire clamp should I use?
Answer: You can use the same size crimping sleeve as your steel wire rope. So with 3 mm steel cable, you also use 3 mm ferrules.
Question: What size wire clamp must I use with plasticized?
You can press through the plastic/PVC. You then choose the same size as the outer casing. So with 3/4 steel cable you choose wire clips of 4mm.
Question: If I buy steel wire in plastic coated PVC 3/4 mm, do I have to strip the wire first and then use 3 mm steel wire clamps?
