Procedure for Shipping Telescope to Arizona;
Containers Required
I. Containers for the Main Telescope
We required the following shipping pallets to ship the whole telescope
to Arizona. We shipped the telescope in the second week of June, 2000,
using essentially these containers.
- Pallet for base: This is an 8x8 foot pallet
with plywood cover. It will contain the following items, many of which are seen
in this loaded view:
- Telescope base and attachment ring for central pivot
- Levelling jacks for the base.
- Insulating material for base.
- Stay bars for altitude.
- Oil distribution line.
- Box with ducts for air lines.
- Fan and external duct.
- Counterweights for tilt axis.
- Tensioning frame for tilt axis.
- Jig for lifting primry mirror.
- Guides for primry mirror.
- Pallet for fork: This is a steel weldment
from ORNL. The fork is placed on the pallet on its side with the central pivot
and brush seals attached. The azimuth bearing and central pivot are protected
by plywood covers. Some parts for the fork (namely the air-filter frames and
access-hole covers) must be shipped separately in a cardboard box.
- Telescope tube (mirror cell): This is an
8x8-foot pallet without cover. The mirror cell is bolted to the pallet with two
1/2-inch threaded rods through existing holes. The tilt axles and attachment points
for the drive sector are protected by plywood shields. The instrument stand is
shipped screwed onto the cell, along with the spare (test) guiding head that goes
on it. The 50-lb counterweights for lateral support are bolted onto the pallet
inside the cell. Back covers for the cell are shipped in place on the cell, held
in place with spare clamps.
- Top end: This is shipped on its assembly fixture,
which is provided with two wooden skids to get it up off the floor for lifting
with a forklift.
- Drive sector and struts: These are contained
in a special box with plywood cover.
- Drive tractors: Three drive tractors, along
with their attachment flexures and support pieces, are shipped in a special box
with a plywood cover.
- Extra moderately sized, heavy parts: These
are shipped in a special box with a plywood cover. They include (a) the azimuth
drive attachments, (b) azimuth hold-downs, and (c) altitude-drive attachment.
- Primary mirror and cover: Use special box
provided by Torus Optics.
- Mirror support levers: Put in a special plywood
box with the levers resting in special wooden cradles to keep them from stressing
the pivot bearings. A loaded view of this box is
shown here.
- Sundry heavy parts: Drive tensioning hardware;
lateral support levers and their attachments; lateral hard points; counterweights for
the tilt tractor; bolts and screws not shipped in other boxes. They go in a
special plywood box.
- Oil pump: Ship in special box with covers.
- Base skirt: These parts go in a special box
made of 1/4-inch plywood.
- Drive electronics: Boxes to house the drive
electronics and computer go in yet another special plywood box.
- Special stand, ladders, air conditioner, spare screws,
misc parts for setting up, special tools in large plastic chest: Take stand apart,
screw together, lash the two ladders and the boxes for other parts on top, and
put on truck as a unit.
- General tools. Take in smaller tool chest in box with cap for top end.
II. Containers for the Miscellaneous Parts to Follow
Some smaller parts were not ready to ship with the main telescope. Specifically,
the secondary mirror was in Iowa for refiguring, the secondary-mirror cell required
tests of its motions in the lab, and the instrument head required further
mechanical/electrical integration in the lab before testing in the telescope,
as well as integration into the spectrograph.
These other parts not yet allocated to boxes are the following:
- Secondary mirror: Ship the mirror in the box
provided by Torus Optics.
- Secondary-mirror cell: This cell requires
a special box to hold it and its stand.
- Instrument head. Ship in another special
box designed to hold it and its stand.
- Drivers for secondary mirror: Try to fit into the box for the mirror
cell, if possible. Otherwise, take in a cardboard box with the lifting
fixture.
III. Containers for the Shipping the Spectrograph
The spectrograph will weigh approximately 2500 lbs., much of which is an optical bench.
We will take it to the site in a small moving van. As of June, 2000, plans for boxing
the various parts are incomplete.
