8 8.2.2 Primary signal person to ground floor garage Lead rigger to M-floor Lookouts/guides to ground floor garage Secondary signal person to the main floor by crane hatch Safety watch to the ground floor garage Note: Observe protocols for signaling and handoff of control for multifloor lifts as described in Cranes SOP, 1000-AD Rotate the dome and move the dome crane trolley to position the 5Ton crane hook over the 4-pt lifting beam, the 4-pt beam can be seen in Figure 2 JHA: SL All personnel should have hard hats on while crane is in motion. Figure 2: 4-pt lifting beam for DESI Spectrograph 8.4 Begin lowering the 5Ton dome crane hook towards the M floor. 8.5 Position and lower hook until it is within reach of M16 hoist ring located on the center-top of the 4-pt lifting beam; move the rolling cart as needed to center the 4-pt lifting beam directly under the hook 8.6 Lead rigger secure the hook to the 4-pt lifting beam M16 hoist ring using the 18 ton shackle and Master link 8.7 Once secure raise the 4-pt lifting beam off its cart and rotate dome such that 4- pt beam is South of dead center of the hatch JHA: CB, CO SL Watch for pinch points as you start to raise the lifting beam. With a suspended load people should not be working underneath load. 8.8 Begin lowering the 4-pt beam to the ground floor, passing through the hatch on the second floor, lead rigger to go down to ground floor at this point 8.9 Lower the hook until the M16 hoist rings on the underside of the 4-pt lifting bean are near eye-level to personnel on the ground floor 2100-AD Docx Page 8 of 16

9 8.10 Rig a 2 ton shackle to each of the M16 hoist rings on the underside of the lifting beam and rig a web sling in vertical configuration to each of the four shackles JHA: CB - Watch for pinch points Lift 4-pt beam such that the bottom of the web slings are approximately 5 feet off the ground, trolley out to go North and put lifting beam above spectrograph Figure 3: DESI Spectrograph, ready for lifting 8.12 Lower lifting beam, with guides at all four corners, until bottom of web slings are approximately 2 ft off the ground JHA: SA Make sure when lowering that 4pt beam does not strike spectrograph, radio communication from primary signaler to crane operator is required. Keep slings from striking the spectrograph Plastic zip ties are used to mark the orientation of the 4pt lifting beam to the Spectrograph. Align the zip ties on the lifting beam M16 hoist ring to the zip ties on the spectrograph M12 hoist ring, as shown in Figure 4 Note: Proper alignment places the lifting fixture central pick point above the Spectrograph CG. Do not proceed until lifting beam alignment is verified and lifting beam is properly centered over the Spectrograph AD Docx Page 9 of 16

10 Figure 4: 4pt Beam Alignment 8.14 Rig web slings to M12 hoist rings on the DESI Spectrograph using the 2 ton shackles 8.15 Remove the 16 screws that attach the DESI Spectrograph to the wire rope isolators, as instructed on page 12 of WS PRO-004-B: Unpacking, Packing and Inspection Procedure of DESI Spectrograph (DESI-3801) 8.16 Slowly raise the hook until web slings begin to become taut, but not fully loaded JHA: CB-watch for pinch points 8.17 Pause, check rigging, and adjust as needed. Lower hook slightly if necessary to adjust. The assembly should appear as it does in Figure AD Docx Page 10 of 16

11 Figure 5: Rigged DESI Spectrograph for lift from Ground floor to M-floor 8.18 Slowly raise the crane hook until the load is floating and continue raising slowly until the DESI Spectrograph is well clear of the Inner Crate base 8.19 Leave Inner Crate in place in case the process must be reversed 8.20 When the DESI Spectrograph remains stable and is not swinging, lift the crane hook at normal speed (starting slowly, and increasing speed incrementally) until the DESI Spectrograph has passed safely through the main floor hatch. JHA: SL Suspended load, make sure no personnel under load, signaler must maintain view of load JHA: CO Make sure load cannot be caught on anything while being raised. Be aware of surroundings Observe the SOP protocols below for hand-off of control from the primary signaler on the ground floor, to the secondary signaler on the main floor Once the DESI Spectrograph has cleared the 3 rd floor all ground-floor personnel EXCEPT the primary signaler should immediately return to the M floor, by the Coude Room After the DESI Spectrograph is safely clear of the main floor hatch and handrails, continue raising and begin rotating the dome so as to position the DESI Spectrograph over the cart near the Coude Room entrance on the M floor, see Figure AD Docx Page 11 of 16

12 Figure 6: Spectrograph set-down location 8.23 Under direction of secondary signaler, lower the DESI Spectrograph until the bottom surfaces of the landing pads are 2 off the cart landing surface, re-position the cart as necessary, see Figure 7. JHA: SL Suspended load, make sure no personnel under load, signaler must maintain view of load NOTE: lookouts/guides may need to gently touch the base of the spectrograph to eliminate swinging while lowering AD Docx Page 12 of 16

13 Figure 7: DESI Spectrograph handling cart 8.24 Under the direction of the secondary signaler, lower the Spectrograph while guides/lookouts check cart alignment and adjust as needed. Prior to set-down lock cart wheels. JHA- CO, SA Be aware of people and objects in the area Begin slowly lowering the dome crane hook at speed 1 so that the DESI Spectrograph makes a soft landing on the cart Once the Spectrograph is fully settled on the cart, lower the crane hook until there is enough slack in the web slings to remove the shackles rigging the slings to the M12 hoist rings Note: Do not leave the removed shackles on the slings, but store them in a safe place that is out of the way, preferably on a rolling cart 8.27 Raise the hook such that the slings cannot catch on the Spectrograph, then move the Spectrograph into the Coude Room for storage using the handling cart 8.28 Lower the hook and remove the remaining rigging and store with the 4-pt beam on the rolling cart 9.0 Procedure Review This procedure must be reviewed if changes are made to the DESI Spectrograph or the 4- point lifting beam that might affect this procedure Records 10.1 JHA Signature Sheet 10.2 Personnel training records 10.3 Rigging 10.4 Critical Lift 2100-AD Docx Page 13 of 16
