Took out the NAB suspension.
- Opened the aluminum pack which covered the NAB suspension in the wooden box (only one-side opened) on the "jambo" cargo.
- Detached some screws which fixed one of the wooden foot beams to the wooden box; the wooden foot beams were for fixing the assembly frame of the NAB suspension structure.
- Pulled up the NAB suspension slightly over the wooden box with a portable gantry crane (Sumner S785103), which was brought from NAOJ. Two slings and four eyebolts were used (one sling for two eyebolts).
- Moved the cargo to open space under the hanged NAB suspension.
- Pulled down the NAB suspension with the assembly frame on the floor; before that, we somehow moved whole the NAB + the crane toward the IYA clean booth from the arm side so that the front wheels of the NAB assembly frame can overcome the difference of floor level in front of the booth entrance.
- Then push the NAB into the IYA clean booth.
Did the first check of the delivered NAB
- Unwrap the final plastic sheet around the NAB suspension in the clean booth.
