[Dsg-rich] Fwd: Eye bolts

[Marc McMullen]

Hi Doug, 

For the RICH stiffening frame design, INFN is requesting some swivel eye bolts (hoist rings) which should at least be rated for 1500Kg. They will need 4 to send to the fab shop for load testing in mid June. Do you have something they could use? If so could you give me the part number so they can adjust the design to the manufacturers dimensions for the hoist rings. 



Thanks,

George, 
you are right and I ask you an help regarding to manage Kg vs Pounds. 

We have to test the tool at 1500 Kg and so we suppose that 3/4" with a rating of 500 Kg each are OK. 
We need at least n.3 of them but to avoid "surprise" our tool can be hang also on four points and so it would be 
better to have the availability of 4 swivel eyebolt. 
Bob Miller said us that this kind of swivel eyebolt are available but must be checked the needed dimension. 

Thanks for the help

I have some questions on this. 

How many hoist rings do you really need for this fixture? Did I really count 7 on the diagram? 

What size hoist rings do you really need for this? M24 are rated at 9250lbs each, do they need to be so big?

Dario, 



I wasn’t sure are we providing the Swivel M24 X 40 Eyebolts? Their pretty expensive and if you already had them I don’t want to buy anymore of them. The ones I found were almost 200$ a piece, so I want to make sure you need them before I budget them in. 



Thank You,
