have a double purpose, as a cradle and a
shield.
I called it sarcophagus, because the FCAL
will stay inside the cradle all the time.

FCAL on Cradle
FCAL Cradle
- The existing cradle can be used with the crane to insert the new FCAL.
24
- The Installation of the new FCAL will be made in
reverse order.
- The new FCAL will install with the existing
cradle.
- To connect the new connectors some tooling is
necessary!!!???
- A lifting table possible to be design (using
mechanical jacking screws), in stead of buying a
scissor table.
- The time to remove the old FCAL and install the
new one, about 6 weeks on each side.
