We live in a ‘flat world’ and equipment is sold around the globe like your daily shopping trip to Walmart. This, of course, includes cranes manufactured on all continents not only in North America. Such cranes come equipped with rope constructions which are not your father’s type. High Performance, high strength non-rotating types, many of them with exotic core configurations, some with plastic extruded cores, some highly compacted, others swage compacted, or both, and some are so called ‘Double-Parallel’ types for super strong applications.
If that would not be enough many of these ropes come equipped with end terminations which are completely different from your ‘tried-and-true flemish eye splice’.
So, what do you do when your customer wants a 23 mm, high strength, non rotating rope with a thimble splice on one end and you only have socket and flemish eye swaging dies and a traditional scissor style- or a 4-poster type swager ?
Worse, if your customer comes to your shop and dumps a pile of boom pendants in from of your test bed, all done with loop back splices, and asks for re-certification and proof testing. Are you sure you understand what this all is ? Can you make an educated analysis to determine if the aluminum swages were done to any approved standard ? Do you know how to identify a proper EN 13411 loop back splice from a ‘home made’ one ? And do you know what to do when the rope used is a bridge strand type ?
If NOT, you better show up for this presentation. To be clear: If YOU are responsible for such tests and procedures DO NOT send your accountant or sales rep …. they likely would not understand what this is all about.
It is not the first time I present this topic; the first time was at the AWRF Conference in Washington DC in April of 2003, more than 10 years ago. At that time many though I was completely off scale and only a few understood the importance.
For the 3rd (third !) time now I will present this topic again in Los Angeles. I will focus on the ‘how-to’ procedures and will introduce and interpret, in detail, the ONLY approved standard there is for such aluminum loop back splices which is the European Standard EN 13411. You can sniff and disagree however bear in mind that, here in the USA and Canada, we DO NOT even have ANY recognized ASME or ASTM standards on ANY wire rope termination. So we better start listening.
I will also invite the so called ‘System Providers’, that are the companies which have developed and tested such loop-back splices, to be present and to answer any and all questions you may have on this topic.
