4 1.0 Purpose This document describes the procedure to lift the DESI spectrograph from the IHF to the truck bed that transports the Spectrograph to the Mayall, and the procedure to lift the Spectrograph off the truck once it reaches the Mayall Telescope. 2.0 Applicability and Starting Conditions Applies to DESI spectrograph forklifting for transport of the spectrograph from the IHF to the Mayall Telescope 2.1 State of the DESI Spectrograph prior to start: DESI Spectrograph shall be packaged and protected inside its inner crate and positioned inside the Outer Crate at the IHF, with front and top covers of Outer Crate removed and base modifications completed (refer to beginning of Section 8.0 for item weights) 2.2 State of the Linde E18C forklift Forklift shall be stored and fully prepped for the move at the IHF 2.3 State of the Linde H40T forklift Forklift shall be stored and fully prepped for the move at the Mayall 3.0 Scope and Analyses This document covers all the steps required to lift the DESI Spectrograph onto the flat-bed truck at the IHF and off the flat-bed truck at the Mayall Telescope 4.0 Definitions 4.1 Outer Crate: Outer shipping crate for the DESI Spectrograph, houses the Inner Crate 4.2 Inner Crate: Inner shipping crate for the DESI Spectrograph; this is re-used so please take care when handling it. 4.3 Winlight: Manufacturer of the DESI Spectrograph 5.0 Training 5.1 Forklift operator training and current certification for operator of Linde E18C and H40T forklifts 6.0 Safety Job Hazard Analysis (JHA) and remediation actions are included in the procedure in red.

6 Table 2: Required Equipment Equipment #/Items Referred To As Linde E18C Forklift 1 E18C Fork Forklift Extensions 2 Forklift extensions Linde H40T Forklift 1 H40T Fork 4400lb capacity pallet jack 1 pallet jack 8.0 Procedure This procedure starts with the DESI Spectrograph inside its Inner Crate, fully enclosed. DESI Spectrograph with Inner Crate - Full assembly minus the cryostats Forklift Extensions Table 3: Weight Summary for Items being lifted Description Approx. Size Weight 2053mm x 1536mm x 821mm 101mm x 1524mm N [2276 lbf] N [92.0 lbf] Task Leader to initial each step as it is completed. 8.1 Verify the DESI Outer Crate has had its front and top removed, along with any insulating foam that may be in the way. Note: Please take care with Outer Crate materials as this crate must be sent back to Winlight to be re-used for future Spectrograph shipments, see Figure AD Docx Page 6 of 18

8 8.3 Deploy personnel as follows: Forklift driver to Linde E18C One signal person, with two lookouts Safety watch to monitor space and personnel 8.4 Install forklift extensions and drive forklift up to crate and position forks under inner crate Note: The Inner Crate is slightly recessed inside the Outer Crate, which will not allow the load to be fully positioned against the backstop of the forklift. This requires an initial re-positioning using the forklift where the Inner Crate is lifted just enough to move across the base of the Outer Crate until there is enough clearance for the forks to fully engage under the load, see Figure 3 Figure 3: Inner Crate re-positioning for lift; note that this is a composite of two images, depicting the ends of the same side of the inner crate. 8.5 Insert forks under the Inner Crate as far as they can reach 8.6 Bring forks up on slowest setting until Inner Crate load is just released from the base of the Outer Crate 8.7 Backup forklift 3-4 or until the front edge of the Inner Crate first meets the foam insulation on the base JHA: CB Keep hands and fingers clear of sides while moving crate. Make sure to be wearing appropriate gloves while working with the wooden crate. 8.8 Lower Inner Crate back down until it is fully supported on the Outer Crate base, drive forklift the rest of the way in until the Inner Crate wall meets the forklift backstop. Note: the forklift extensions are 60 and the Inner Crate is 70 deep, so the forks will not contact the backside of the Outer Crate. 8.9 Gently lift the Inner Crate and pull it clear of the Outer Crate, see Figure AD Docx Page 8 of 18

9 Figure 4: Inner Crate clear of the Outer Crate 8.10 Pause and check the forklift and load, make sure everything looks balanced for placement onto flatbed JHA: CB, CW, SL Suspended load, use caution around forklift. Make sure area is clear of people and objects that could be in the way. Use caution while transitioning the load from the building to the flatbed Raise garage door and make single point turn to drive forklift onto loading bay, see Figure Note: Watch for transition between building and loading bay, drive slowly 2100-AD Docx Page 9 of 18

10 Figure 5: Forklift turn to place crate on truck 8.12 Load Inner Crate onto the flatbed near cab of the truck, lower softly onto bed, see red box in Figure 5 JHA: CB, CW,SA Make sure forks are correct height to not strike truck bed, most likely the loading bay is lower than the truck bed. Use caution while transitioning load from the building on to the flatbed Pull forklift back and make sure forks are clear of the Inner Crate before raising forks or making turns 8.14 Strap crate down to bed 8.15 Store Linde E18C forklift for future lifts 8.16 DESI Spectrograph is driven from the IHF to the Mayall following the route outlined in red in Figure 6 JHA: CB, CW While walking alongside truck, take care to not come in contact with the truck and maintain safe distance. Be aware of your surroundings Note: DESI Spectrograph shall not be moved in inclement weather (or if ambient is below 0 C), this includes any weather conditions that would forbid dome crane use at the Mayall Note: Prior to move, recon and inspect the whole route for an obstacles that could hinder the move Note: Kitt Peak traffic controls shall be used where necessary to ensure safe load transport as well as safety to visitors 2100-AD Docx Page 10 of 18

11 Figure 6: Flatbed truck route for DESI Spectrograph move from IHF to Mayall 8.17 Deploy personnel as follows: Forklift driver to Linde H40T One signal person with two lookouts Safety watch to monitor space and personnel 8.18 Truck is pulled up to the ground floor garage door at the Mayall 8.19 Linde H40T forklift is sufficiently fueled ready to move Inner Crate 8.20 Drive Linde H40T to truck and position forks under the DESI Spectrograph Inner Crate, make sure forks fully engage under the load, see Figure 7 JHA: SA Make sure forks are correct height to not strike truck bed or crate AD Docx Page 11 of 18

12 Figure 7: Linde H40T forklift with forks under Inner Crate 8.21 Pause, check forklift and load, and adjust as needed 8.22 Slowly raise the forklift until the base of the Inner Crate clears the truck bed by 1 to 2 JHA: CB, CW, SL Suspended load, use caution around forklift. Make sure area is clear of people and objects before moving load from flat-bed to the garage. Use caution while transitioning load from the building on to the flatbed Back-up forklift from truck, make sure there is sufficient clearance under the garage door, see Figure Lower the forks until they are a few inches above the ground for the remaining maneuvers AD Docx Page 12 of 18

13 Figure 8: Linde H40T lifts Inner Crate and backs up away from the truck 8.25 Make a single point turn to center the Inner Crate under the hatch, as seen in Figure Note: Take care to avoid rails for primary mirror; forklift should be centered between rails AD Docx Page 13 of 18

14 Figure 9: Linde H40T move to position the DESI Spectrograph near the dome hatch 8.26 Slowly lower Inner Crate for soft landing centered under the dome hatch, back forklift away, do not raise forks or turn until clear of crate JHA: CO, SA Be aware of surroundings as you back away from the load. 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 AD Docx Page 14 of 18
