1.0 Purpose This document describes the procedure to lift the DESI spectrograph and Inner Crate out of the Outer Crate and position the Inner Crate for unpacking and eventual Spectrograph transport to the M-floor.+

2.0 Applicability and Starting Conditions

Applies to DESI Spectrograph forklifting for removal of the Spectrograph + Inner Crate from the Outer Crate on the Mayall ground floor:

2.1 State of the DESI Spectrograph prior to start: 2.1.1 DESI Spectrograph shall be packaged and protected inside its Inner Crate and

Outer Crate at the Mayall 2.1.2 Front and top covers of Outer Crate removed, with crossbar, brackets and ratchet

straps removed, front cover should face the Mayall garage door (See DESI-3801 for unpackaging instructions).

2.2 State of the Linde H40T forklift: 2.2.1 Forklift shall be 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, while inside the Inner Crate, from the Outer Crate for eventual transport to the Mayall M-floor

4.0 Definitions

Task Leader to initial each step as it is completed.

7.1 ____Unpack Outer Crate per the Winlight Procedure, as documented in the Appendix of this document, also refer to DESI-3801 7.1.1 Remove cover using 3-ton crane and 4-leg bridle 7.1.2 Remove front panel by hand 7.1.3 Remove lateral beam (no screws, lifts out) 7.1.4 Remove ratchet strap 7.1.5 Remove metal brackets 7.2 ____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 1.

7.3 ____DESI Outer Crate is positioned on the Mayall garage floor as shown in Figure 2

8.0 ____Deploy personnel as follows: 8.1.1 Forklift driver to Linde H40T

8.1.2 One signal person, with two lookouts (lookout may be signal person) 8.1.3 Safety watch to monitor space and personnel

9.0 Drive forklift up to crate and position forks under inner crate as seen in Figure 3.

Figure 3: Forklift under Inner Crate

9.1.1 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 slightly to allow shifting across the base of the Outer Crate until there is enough clearance for the forks to fully engage under the load, see Figure 4

Figure 4: Inner Crate re-positioning for lift

10.0 Insert forks under the Inner Crate as far as they can reach 11.0 Bring forks up on slowest setting until Inner Crate load is just released from the base of

the Outer Crate 12.0 Backup forklift 3”-4” or until the front edge of the Inner Crate first meets the foam

insulation on the base 12.1.1 Note: Station lookouts on both sides to watch for clearance and damage to

Outer Crate

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.

13.0 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 forks are 72” and the Inner Crate is 70” deep, so the forks will protrude beyond the backside of it by ~2”. Spotters are necessary to watch so as the forks don’t damage the outer crate.

14.0 Gently lift the Inner Crate and pull it clear of the Outer Crate 15.0 Pause and check the forklift and load, back Inner Crate away from Outer Crate as

shown in Figure 5 JHA: SL – Suspended load, use caution around forklift. Make sure area is clear of people and objects that could be in the way.

Figure 5: Linde H40T lifts Inner Crate and backs up away from the truck

16.0 Backup the forklift straight back from the crate, completely out of the garage 16.1 ____Move Outer Crate with pallet jack as far as possible into the clean tent

16.2 ____Bring forklift back into garage and drive Inner Crate to target zone, under the hatch opening.

Figure 8: DESI Spectrograph under the dome hatch

17.0 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.

18.0 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.
