However, there are several configurations for lifting the detector, so they may use as few as 3. The fab shop needs them to pick a size for the hoist ring mounts, and I would rather overrate (bigger hoist ring) using something Hall B has plenty of than just taking the approximate load weight and dividing. I'll swing by the hall today and see whats on hand.

>> 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.

>> 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.
