A turnback involves turning a piece of wire back onto itself and clamping it down with a sleeve or clips. A flemished eye involves taking the wire apart turning the wire back on itself and weaving it back together. A flemish eye is more reliable if a sleeve fails or you have no sleeve at all.
Hey, great video, thanks. I did want to add as an Ironworker i prefer the hand splice because of the render on the choke more then it getting snagged under the load (though that's a factor). When we send a piece up we're usually only using one choker and it's critical that the piece is straight up and down (no "roll") and typically the knuckle of a mechanical splice will either land right on the flange creating an opportunity for it to jump one way or the other or it'll catch under the flange putting extra weight on that knuckle. Which probably isn't good. My question though is, is there a good rule of thumb for how much capacity you lose with a hand spice compared to the mechanical?
So, I'm not sure exactly what you are asking, so I have two answers for you depending on what you meant. If you are saying you hand-splice a sling and then put a carbon sleeve over the body of the splice, then NO. You don’t want to do that. We have already performed the “splice by opening up the s strands and 3 strands + core and performed the splice back onto themselves, forming the eye. We then have small tails on the Mechanically spliced sling that get tucked around the neck, and the carbon steel sleeve is pulled over them and hammered into place prior to putting them into the swagger. If you are asking if you can have a sling with a hand-splice taper and conceal eye on one end and a mechanical splice eye on the other, then YES. That is being used quite heavily with ironworkers to have the mechanical splice eye in the hook of the crane (the same end that has the tag on it to protect the tag from damage), and the hand-splice end is being used to choke the load and does not have a carbon steel sleeve on it to obstruct the slings from pulling out from under the load easily. So recap - Do not put a carbon steel sleeve on a hand-spliced taper and conceal-eyed sling. But you can have different style eyes on the ends of one sling.
Great video very educational Thanks
Glad it was helpful! Thanks for watching!
Excellent training material. Mazzella provides considerable technical info on rigging practices and all is excellent.
Thanks for watching! Glad you found it useful!
How do you tell the difference between a flemished eye and turn back eye with fittings?
You should be able to see the tail end folded back when using a turnback.
A turnback involves turning a piece of wire back onto itself and clamping it down with a sleeve or clips.
A flemished eye involves taking the wire apart turning the wire back on itself and weaving it back together.
A flemish eye is more reliable if a sleeve fails or you have no sleeve at all.
Excellent

How about hand splice plus carbon steel? is this advisable to use for lifting?what is the most advisable to use to lifting?

Thank you for good explanation@@LiftingandRigging
Do you do a vudeo on wire rope lubes?
