I needed to lift part of a mill today and I wasn’t comfortable with the inch and a quarter shackles I had. The mill column had a weight written on it that was 5k above the inch and a quarter Crosby shackle rating that I had and I wasn’t sure if the counterweight was included in the weight scrawled on the side of the machine. After some discussion with one of my engineers, I decided to get some larger shackles.
I drove over to VanPort Wire Rope and Rigging and asked what they had for 17 ton shackles. Import units emblazoned with a China label were $38.00 and domestic made in USA were $148.00 . . . I decided that picking a 15+ ton load was worth a few hundred dollars and got a pair of the domestic units. They had thicker section shackles, higher quality machined threads and better galvanized finish. For roughly 4x the price it was some consolation to have better looking units with the made in USA forged into the body.
Anyone have comparable experience with the import vs domestic shackles?

In the end, a no drama pick and set. Tomorrow the X-axis ways get set and then we hang the Z and Y axes. Glad to finally have time to start putting this thing together.
