Initial Conditions

  • Instrument in LCO cleanroom on legs

Preparations

  • If operating, shut down MagAO-X.

    • Make sure to leave stages/wheels in positions that are safe for transportation

    • Complete procedure in the telescope removal procedure

  • Prepare Legs for Move

    • Turn off table legs (table air power off, PEPS II rocker switch off) and remove air connection from wall

    • Lie under table and remove all three (#1,2,& 3) geophones from bottom of table

    • Place coiled up geophones and cables into basket

    • Unplug PEPS II power from side of rack

    • Remove the taped down exhaust line from the clean room floor

  • Remove all cables

    • See detailed procedure for removing 2K DM cables

  • Electronics Rack

    • Ensure that roll-out shelves are restrained

    • If not installed, install side panels

    • Close and lock doors

    • Tape keys down

  • Instrument

    • Remove eyepiece

    • Place freezer baggie over top periscope mirror so it does not fall on pyramid

    • Turn off blower, and remove hose

    • Tape over any exposed holes (from cables, etc)

    • Secure any loose cables

    • Shrink wrap the instrument

    • Install solar blanked over shrink wrap

  • Cart and Rigging

    • Verify all cart hardware is in-hand

    • Verify two wire harnesses are in hand

    • Partially assemble cart, leaving one long side off

    • Store cart out of the way so table can roll into unpacking area

  • Dome

    • The NASE platform shoud be clear and ready for MagAO-X installation

    • The dome jib crane should be set to “3 hairs” speed

  • XKID

    • If XKID is pre-cooling on the platform:

      • move the electronics to the dome floor

      • move the dewar to the corner of the platform

      • ensure cables are routed to minimize interference

Rig Onto Cart

  • Lower table legs onto the casters by turning the 16 leveling bolts, and remove the 12 metal pads

  • Roll the instrument out of the cleanroom

    NOTE: At least 4 people required, 2 to push, 2 to hold the cleanroom sides open

    CAUTION: only push on the legs, not the table itself

  • Continue rolling the instrument through the garage door into the unpacking area

  • Move the cart, currently with 3 sides, around the legs

    CAUTION: be careful to not bump the legs with the cart

  • Attach the 4th side of the cart

  • Ensure that the 8 large bolts on the cart are snug but not tight

  • Attach the lifting wire-harness to each side of the cart. The hooks should point outward.

  • Attach the load spreader with straight extensions to the crane, using a crane scale

    ../_images/load_spreader_attach.jpg

    The load spreader attached to the crane for lifting the cart

  • Place the load spreader in the center position (the cart is symmetric)

  • Lift the load spreader, and position it over the instrument

  • Being careful to not bump the instrument, lower the load spreader and attach the lifting harness D rings. Use 4x shackles to extend the length to reach the cart on the floor.

    ../_images/cart_lift_extensions.jpg

    Lifting harnesses attached with shackle extensions

  • Position a person at each corner of the cart

    CAUTION: Do not allow the cart to bump the legs or the table uncontrolled

  • Slowly lift the cart (320 lbs) until it is touching the bottom of the table.

    ../_images/cart_lift_tofrom_table.jpg

    The cart being lifted to the bottom of the table. Note the direction of the hooks.

  • Install the 4 bolts. Loosen bolts on the cart as needed.

  • Once the cart is bolted to the table bottom, while 320 lbs is still on the crane, tighten all cart bolts. Do not over-tighten, make 1/4 turn after the washers are no longer free. This is to avoid excessive stress on the table.

  • Install the triangle stabilizing ropes between the crane hook and the lifting fixture IAW the below figure. Tighten, but do not cause them to pick the load.

    ../_images/stabilizers.jpg

    The triangle stabilizing ropes should be tight, but not become the lifting point for the load.

    CAUTION: be sure that the load spread does not hit the cart when being repositioned.

  • Reposition the load spreader center to the instrument + cart position marked on it.

  • Ensure that there is room to move the legs out from under the table, opening the garage door into the cleanroom if necessary.

  • Position a person at each corner of the cart to stabilize it during the lift.

  • Position two people to remove the legs from under the table

  • Begin SLOWLY lifting the table off the legs. Once table is fully supported by the crane, the scale will read around 2000 lbs (as of March 2024).

  • Go up 0.5inch then stop and inspect the platters. Use a long flathead screwdriver to very gently pry any stuck platters off bottom of table.

  • Move the legs out from under the table.

    ../_images/cart_lift_legs_ready.jpg

    The cart and instrument ready to be set down on the wheels, with legs out of the way.

  • Set the cart down on its wheels.

  • Re-check the cart bolts. Tighten any that are loose to 1/4 turn past when the washers stop moving.

Transport MagAO-X To Clay

  • Move MagAO-X onto the lift gate (using plates over the gap)

    ../_images/inst_onto_pentalift.jpg

    MagAO-X moved onto the pentalift. Note the metal plates across the gap.

  • Raise the lift-gate to the height of the flatbed truck
