SECTION 3
UPPER MOUNT INSTALLATION PROCEDURES
This section contains procedures for installing the upper mount
hardware. This hardware includes the rotating frame,
azimuth/elevation drives, hub, and work platform of the
16-/18-Meter Earth Station Antenna. The installation of the lower
mount is contained in Section 2 and the installation of the reflector,
spars, subreflector, and feed is contained in Section 4. General
safety precautions and procedures for the entire installation are
described in Section 2 and should be reviewed before proceeding
with these procedures.
GENERAL
Perform the following procedure to install the azimuth drive
anchor. This should be accomplished prior to installing the
rotating frame (azimuth frame and alignment assembly).
AZIMUTH DRIVE
ANCHOR
INSTALLATION
1. Determine center of optimum azimuth sector to locate azimuth drive
anchor (item 2 in Figure 3-1). See Figure 3-1, Sheet 2.
2. Install azimuth drive anchor to azimuth frame and alignment
assembly (item 4) using 2 azimuth anchor spacer plates (item 25), 2
azimuth anchor pins (item 3), 12 hex head bolts (item 102), and 12
flat washers (item 107).
Perform the following procedure to install the rotating frame.
ROTATING FRAME
INSTALLATION
1. Determine center of optimum azimuth sector to locate azimuth frame
and alignment assembly. See Figure 3-1, Sheet 2. The center of
azimuth travel in the sector should be as closely aligned to the test
satellite position as possible.
2. Remove necessary bolts for installing azimuth frame and alignment
assembly. (See Figure 3-2 and 3-3 for the assembly drawings for
azimuth frame and alignment assembly.)
WARNING
__________________________________________
The azimuth frame and alignment
assembly
weighs 18,000 lbs (8,165 kg). Use extreme care
when hoisting the assembly into position.
