  • Plan – just back in
  • Constraints

– Roll-up door is 16’ wide – Usable area of dock is ~12’ X 58’ – Tail end of trailer must be unobstructed - if we use a roll-tite trailer, it must roll towards the cab – If significant on-trailer work is needed, we may want a short trailer so that the roll- up door can be closed if weather is bad

  • Plan

– Rig HWR under crane – Take slack out of slings – Free HWR from trailer – Lift

  • Constraints

– Structure to be cleared on trailer cannot exceed 10.5’ cave height – Not much room to work around the trailer – 20T crane capacity

  • Hoist points on HWR lid
  • Simple 4-sling rigging arrangement
  • Same rigging to be used at ANL

  • Compatible spreader bar is available
  • Trade-off: Spreader bar offers better geometry (lower

profile, lower sling angles), but requires handling over HWR Alternate Rigging layout

  • Plan

– Crane over south cave wall – Tag lines to control rotation – Land on blocks in PIP2IT cave, downstream of final position – Idea is to provide good access all the way around the module

  • Constraints

– 10.5’ south cave wall height

  • Plan

– Work specified by ANL, not covered in this presentation

  • Constraints

– May not have continuous crane coverage due to schedule interactions with CMTS1 work (LCLS2)

  • Plan

– Lift and translate upstream in PIP2IT cave – Land on cribbing within 25mm of nominal position

  • Constraints

– Less stringent vertical constraints than other craning operations – Typically, we are able to set with ~10mm accuracy at CMTS

SLIDE 18
  • Plan

– With HWR sitting rigidly on cribbing, interface adjustment struts – Use adjustment struts to transfer load – Remove cribbing – Rough align HWR

  • Constraints – cribbing needs to avoid couplers
