Lapse Video of Telescope Integration
A two minute video showing the telescope integration process that
took two days to complete.
A 14,000 pound specially engineered lifting
tool was attached to the telescope (lower right corner, above
the aircraft wing) and expertly lifted alternately and in tandem
by a 210 ton crane and a 75 ton crane. This lift proceeded
over a two day period, much of the time controlled and progessing
only a fraction of an inch at a time, until the entire 34,000
lbs load cleared the main sill beam of the aircraft, was lowered
into the aircraft cavity, moved forward and attached in place
to the forward bulkhead of the aircraft. Clearances of this load
at entry into the aircraft were at several points less than 4
inches and the attachment points where the load mated to the
bulkhead had been precisely engineered to accept the bolt-up
exactly as planned. After attachment of the telescope to
the bulkhead, the second crane was moved into position and attached
to the lifting device.
Over the following two hours, loads were
transferred alternately in 200 to 500 lbs increments to the second
crane,
insuring a gradual transfer of the 19,800 lbs SUA weight to the
aircraft bulkhead. Additionally, this weight transfer process
insured the 14,000 lbs lifting device could be lifted back out
of the cavity with a center of gravity and no induced kick-loading
from the telescope weight. The process worked as planned
and the lifting device was safely and accurately removed from
the cavity, thus successfully completing installation of the
telescope.
