BBSS Put in Can

Randy, Ibrahim

Randy and I put the BBSS in the can today, as shown by pictures.

Following LLO's advice from their experiences in alog 79950, we were able to use the aluma lift to can the BBSS. What we did in order:

1. Strip locked-mass BBSS of all cables, check for looseness, bring alum-a-lift into position to lift BBSS from lifitng bars

2. Undo dog clamps to let lift take suspension load, ensure suspension is secured on the lift. Move BBSS out of test stand - as LLO said, very small clearance.

3. Prepare temporary platform for lift fork adjustment

4. Set BBSS on temporary platform - this part was successful but needed extra blocks to avoid interference with Y-bracks on the Lower Structure.

5. Adjust forks to be allow for canning without bottoming out, relift.

6. Put into wiped-down can and check for looseness. Rewipe, check for particulate and ensure secure fit

7. Close doors.

See pictures below.

Ibrahim, Randy

Randy and I opened the can to:

  • Take out BRDs - were left in but best to remove during the move to OSB and craning since they're somewhat fragile and can swing.
  • Insert D2300392 Transport Pads under Dummy - for safety during big move
  • Insert brackets to secure attachment between transport plate (attached to Lower Structure) and can.

See pictures below for each and another overall image.

We then buttoned the BBSS and tightened all screws. It is now ready for transport.
