Splicing FAQ

Quick tutorials with tips, tricks and answers to frequently asked questions – perfect for learners who love to read a manual.

Ferrules

How do I swage an aluminum ferrule according to EN 13411-3?

Please take a look at our splicing instructions for the ferrules ZEN 13411-3 (cylindrical) and ZEN 13411-3 Type C (conical).

Which wire ropes are suitable for turn-back terminations acc. to EN 13411-3?

Single layer, rotation resistant and parallel-closed stranded ropes conforming to EN 12385-4, stranded ropes conforming to EN 12385-5, spiral strand ropes conforming to EN 12385-10 and cable-laid ropes as specified in EN 13414-3. The maximum rope grade specified in the standard is 1960 N/mm². The types of rope lay shall be Ordinary or Lang lay.

Why is the inspection hole of my ZEN 13411-3 Type C ferrule closed after swaging?

Most likely, the ferrule is positioned too far into the conical part of the swaging dies. Please note our splicing instructions.

Which ferrule size is suitable for my rope?

The correct allocation of rope and ferrule depends on the ferrule type and wire rope details. Please take a look at our splicing charts that you can find on the product pages of our ferrules.

Is an aluminium ferrule suitable for a stainless steel wire rope?

NO! The aluminium ferrule would dissolve over time due to galvanic corrosion. Please use stainless steel or copper ferrules.

Can I use the same swaging dies for aluminium/copper and steel/stainless steel ferrules?

NO! Swaging dies for aluminium and copper ferrules have cutting edges for the excess material. These cuttting edges would be damaged if you use them for steel or stainless steel. Furthermore, these swaging dies have a different degree of hardness. Besides this general rule, you need special swaging dies for some of our ferrules due to a special diameter or shape after swaging.

Swaging Machines

Which are the advantages of a 1-column press?
The C-shape improves the accessability and this leads to a faster production cycle.
Which are the benefits of a down-stroke pressing machine?
Thanks to the fact that the piston comes from above, the workpiece remains in position during the swaging process and the seals are protected against dirt. In addition to that, the working height of our 2000t/4000t swagers is reduced and that makes ground works or a platform around the machine unneccessary.
When does a swaging machine have to be serviced? Whom can I contact?
Swaging presses operate with high hydraulic pressure. Depending on the use of the machine, we recommend an annual inspection. Please contact us.
Why does my swaging press not reach the maximum pressing force?
This indicates a loss of oil pressure and may have various causes. Please contact us.

Test Beds

What can I test on a SAHM SPLICE test bed?
These test beds are specially designed for non-destructive and destructive testing of wire ropes, fiber ropes, webbing slings, chains, shackles and other lifting devices etc. according to EN 12385 and EN 2307.
Which test types are available as a standard?
Various manual and automated test programs are available, including: Standard strength test, Strength testing with load holding, Destruction test according to EN12385 and EN 2307 (fiber cables), Cyclic life tests
Is there a load limit for destruction tests on SAHM SPLICE test beds?
No, our tensile testing machines can perform break tests up to 100% of their capacity.
Can the results be saved / printed?
Yes! The measurement data of the test are stored and can be processed as raw data in the EXCEL format at any time via a network or USB interface. The test report is automatically output in PDF format and is optionally available in German or English (other languages on request).
How often does my test bed have to be calibrated and who does it?
In accordance with EN ISO 7500-1, the machine should be calibrated every 12 months at the latest or when a major repair took place. We offer worldwide calibration service up to 6MN. Please contact us.
Does SAHM SPLICE also provide service and maintenance?
Yes, besides the annual calibration, we can adjust and maintain your machine as desired. In addition, our tensile testing machines have remote maintenance access.
Is it possible to equip my old test bed with a new control system?
Yes, SAHM SPLICE has modernized many tensile testing machines. Please contact us.

Cutting & Annealing Machines

Why do the annealing machines 1224/1225/1226 have two hand wheels?
The reason for this is the wire rope construction. Depending on the direction of the rope, you should use the left or right wheel, in order to reach the best possible result.
How do I increase the life time of my annealing machine?
By keeping the machine and especially the clamping jaws and other contact surfaces clean. In addition you should lubricate our machines 1224/1225/1226 with grease daily. Please follow the instructions of our operator’s manual.

Tools & Accessories

How can I increase the life time of my swaging dies?
Make sure that the dies are properly aligned and clean. Grease the swaging bores before each swaging process and do not use more pressure than necessary.
How do I know that I need new swaging dies?
The indications are:
  • Ferrule diameter after swaging is too large or too small
  • Ferrule is stuck in the swaging dies after swaging
  • The cutting edges are bent
  • The swaging dies show cracks
Why shouldn’t I use damaged swaging dies?
Defective swaging dies can lead to injuries and insufficient swaging results.
Can I use the same swaging dies for aluminium/copper and steel/stainless steel ferrules?

NO! Swaging dies for aluminium and copper ferrules have cutting edges for the excess material. These cuttting edges would be damaged if you use them for steel or stainless steel. Furthermore, these swaging dies have a different degree of hardness. Besides this general rule, you need special swaging dies for some of our ferrules due to a special diameter or shape after swaging.

Can I swage and mark the ferrules in one step with your marking system?
No. The marking of the aluminium ferrule needs less pressure. If you do it in one step or with full pressure, you would reduce the life time of the marking plates.
